Master the Isaca CISA Exam: Essential Study Tips and Strategies

 In the development of a new financial application, the IS auditor’s first involvement should be in the feasibility study. A feasibility study is a preliminary analysis that evaluates the technical, operational, economic, and legal aspects of a proposed project or system. A feasibility study helps determine whether the project or system is viable, feasible, and desirable for the organization and its stakeholders.

The IS auditor’s role in the feasibility study is to provide an independent and objective assessment of the project or system’s risks, benefits, costs, and impacts. The IS auditor should also ensure that the feasibility study follows a structured and systematic approach, considers all relevant factors and alternatives, and complies with the organization’s policies and standards. The IS auditor should also verify that the feasibility study is documented and communicated to the appropriate decision-makers.

The IS auditor’s involvement in the feasibility study is important because it can help:

Identify and mitigate potential risks and issues that could affect the project or system’s success

Evaluate and justify the project or system’s alignment with the organization’s strategy, goals, and value proposition

Estimate and optimize the project or system’s resources, budget, schedule, and quality

Assess and enhance the project or system’s security, reliability, performance, and usability

Ensure that the project or system meets the expectations and requirements of the users and other stakeholders

The other three options are not the first involvement of the IS auditor in the development of a new financial application, although they may be part of the subsequent stages of the development process. Control design is the process of defining and implementing controls that ensure the security, integrity, availability, and efficiency of the system. Application design is the process of specifying the functional and technical features of the system. System test is the process of verifying that the system meets the specifications and requirements.

Therefore, feasibility study is the best answer.

 The technology that has the smallest maximum range for data transmission between devices is near-field communication (NFC). NFC is a short-range wireless technology that enables two devices to communicate when they are in close proximity, usually within a few centimeters. NFC is commonly used for contactless payments, smart cards, and device pairing. According to the Bluetooth® Technology Website1, the effective range of NFC is less than a meter, while the other technologies have much longer ranges. Wi-Fi can reach up to 100 meters indoors and 300 meters outdoors2. Bluetooth can reach up to 800 feet with Bluetooth 5.0 specification3. Long-term evolution (LTE) can reach up to several kilometers depending on the cell tower and the device4.

A firewall between internal network segments improves security and reduces risk by inspecting all traffic flowing between network segments and applying security policies. This will prevent unauthorized or malicious access, data leakage, or network attacks from compromising the network resources or data. Logging all packets passing through network segments may provide audit trails and evidence, but not prevent or mitigate security incidents. Monitoring and reporting on sessions between network participants may help to identify anomalous or suspicious activities, but not block or filter them. Ensuring all connecting systems have appropriate security controls enabled may enhance the overall network security posture, but not isolate or segregate different network segments. References: Info Technology & Systems Resources | COBIT, Risk, Governance … - ISACA, section “Book COBIT 2019 Design Guide: Designing an Information and Technology Governance Solution | Digital | English”

The answer A is correct because the greatest concern for an IS auditor when a data owner assigns an incorrect classification level to data is that controls to adequately safeguard the data may not be applied. Data classification is the process of categorizing data assets based on their information sensitivity and business impact. Data classification helps organizations to identify, protect, and manage their data according to their value and risk. Data owners are the individuals or entities who have the authority and responsibility to define, classify, and control the access and use of their data.

Data classification typically involves assigning labels or tags to data assets, such as public, internal, confidential, or restricted. These labels indicate the level of protection and handling required for the data. Based on the data classification, organizations can implement appropriate controls to safeguard the data, such as encryption, access control lists, audit logs, backup policies, etc. These controls help to prevent unauthorized access, disclosure, modification, or loss of data, and to ensure compliance with relevant laws and regulations.

If a data owner assigns an incorrect classification level to data, it can result in either underprotection or overprotection of the data. Underprotection means that the data is classified at a lower level than it should be, which exposes it to higher risks of compromise or breach. For example, if a data owner classifies personal health information (PHI) as public instead of confidential, it may allow anyone to access or share the data without proper authorization or consent. This can violate the privacy rights of the data subjects and the compliance requirements of regulations such as HIPAA (Health Insurance Portability and Accountability Act). Overprotection means that the data is classified at a higher level than it should be, which limits its availability or usability. For example, if a data owner classifies marketing materials as restricted instead of public, it may prevent potential customers or partners from accessing or viewing the data. This can reduce the business value and opportunities of the data.

Therefore, an IS auditor should be concerned about the accuracy and consistency of data classification by data owners, as it affects the security and efficiency of data management. An IS auditor should review the policies and procedures for data classification, verify that the data owners have adequate knowledge and skills to classify their data, and test that the data classification labels match with the actual sensitivity and impact of the data.

The answer D is correct because the greatest concern for an IS auditor with the situation of business owners being removed from the project initiation phase is that the requirements may be incomplete. The project initiation phase is the first step in starting a new project, where the project’s purpose, scope, objectives, and deliverables are defined and documented. The project initiation phase also involves identifying and engaging the key stakeholders who have an interest or influence in the project, such as sponsors, customers, users, or business owners.

Business owners are the individuals or entities who have the authority and responsibility to define the business needs and expectations for the project. They are also the primary beneficiaries of the project outcomes and benefits. Business owners play a crucial role in the project initiation phase, as they provide valuable input and feedback on the requirements and specifications of the project. Requirements are the statements that describe what the project should accomplish or deliver to meet the business needs and expectations. Requirements are essential for guiding the project planning, execution, monitoring, and closure phases.

If business owners are removed from the project initiation phase, it can result in incomplete or inaccurate requirements, which can have negative impacts on the project’s quality, scope, time, cost, and risk. Some of the possible consequences of incomplete requirements are:

Misalignment: The project may not align with the business strategy, vision, or goals, which can reduce its value or relevance.

Confusion: The project team may not have a clear understanding of what the project should achieve or deliver, which can affect their performance or productivity.

Rework: The project may need to undergo frequent changes or revisions to accommodate new or modified requirements, which can increase the time and cost of the project.

Dissatisfaction: The project may not meet the expectations or satisfaction of the business owners or other stakeholders, which can affect their acceptance or support of the project.

Failure: The project may not deliver the expected outcomes or benefits, which can affect its success or viability.

Therefore, an IS auditor should be concerned about the involvement and participation of business owners in the project initiation phase, as it affects the completeness and quality of requirements. An IS auditor should review the policies and procedures for stakeholder identification and engagement, verify that the business owners have adequate knowledge and skills to define their requirements, and test that the requirements are well-defined, documented, approved, and communicated.

The auditor’s best course of action after discovering instances where employees shared license keys to critical pieces of business software is to verify whether the licensing agreement allows shared use. A licensing agreement is a contract between the software provider and the user that defines the terms and conditions of using the software, including the number, type, and scope of licenses granted. Some licensing agreements may allow shared use of license keys among multiple users or devices, while others may prohibit or restrict such use. By verifying the licensing agreement, the auditor can determine whether the employees violated the contract or not, and whether there are any legal or financial risks or implications for the organization.

The other options are not as appropriate as option D, as they may not address the root cause of the issue or provide a comprehensive solution. Recommending the utilization of software licensing monitoring tools may help prevent or detect future instances of license key sharing, but it does not resolve the current situation or ensure compliance with the licensing agreement. Recommending the purchase of additional software license keys may be unnecessary or wasteful if the licensing agreement already allows shared use or if there are unused licenses available. Validating user need for shared software licenses may help identify the reasons or motivations behind license key sharing, but it does not justify or excuse such behavior if it violates the licensing agreement.

Full disk encryption (FDE) is a means of protecting information by encrypting all of the data on a disk, including temporary files, programs, and system files1. FDE is best suited for addressing the risk scenario of physical theft of media on which information is stored, as it prevents unauthorized access to the data even if the device is lost or stolen2. FDE does not prevent data leakage as a result of employees leaving to work for competitors, as they may still have access to the data while using the device or copy the data to another device before leaving. FDE does not prevent noncompliance fines related to storage of regulated information, as it does not ensure that the data is stored in accordance with the applicable laws and regulations. FDE does not prevent unauthorized logical access to information through an application interface, as it does not control the access rights and permissions of users and applications. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 2402 Planning, “The IS audit and assurance professional should identify and assess risk relevant to the area under review.” 3 One of the risk factors to consider is “the sensitivity of information processed, stored or transmitted by the system” 3. FDE is one of the possible controls to mitigate the risk of unauthorized disclosure of sensitive information due to physical theft of media.

 The most important thing to assess when conducting a business impact analysis (BIA) is the completeness of critical asset inventory. This is because the critical asset inventory is the basis for identifying and prioritizing the business processes, functions, and resources that are essential for the continuity of operations. The critical asset inventory should include both tangible and intangible assets, such as hardware, software, data, personnel, facilities, contracts, and reputation. The critical asset inventory should also be updated regularly to reflect any changes in the business environment or needs. References:

CISA Review Manual (Digital Version), Chapter 5, Section 5.41

CISA Online Review Course, Domain 3, Module 3, Lesson 12

 The primary reason to perform a risk assessment is to determine the current risk profile of the organization, which is the level of risk exposure and the likelihood and impact of potential threats. This will help the organization to identify and prioritize the risks that need to be addressed and to align the risk management strategy with the business objectives. A risk assessment may also help to achieve compliance, support the BIA, and allocate budget, but these are not the primary reasons. References: ISACA Glossary of Terms, section “risk assessment”

The most important responsibility of user departments associated with program changes is approving changes before implementation. This is because user departments are the primary stakeholders and beneficiaries of the program changes, and they need to ensure that the changes meet their requirements, expectations, and objectives. User departments also need to approve the changes before implementation to avoid unauthorized, unnecessary, or erroneous changes that could affect the functionality, performance, or security of the program.

Providing unit test data is a responsibility of user departments associated with program changes, but it is not the most important one. Unit test data is used to verify that the individual components of the program work as expected after the changes. However, unit test data alone cannot guarantee that the program as a whole works correctly, or that the changes are aligned with the user departments’ needs.

Analyzing change requests is a responsibility of user departments associated with program changes, but it is not the most important one. Analyzing change requests is the process of evaluating the feasibility, necessity, and impact of the proposed changes. However, analyzing change requests does not ensure that the changes are implemented correctly, or that they are acceptable to the user departments.

Updating documentation to reflect latest changes is a responsibility of user departments associated with program changes, but it is not the most important one. Updating documentation is the process of maintaining accurate and complete records of the program’s specifications, features, and functions after the changes. However, updating documentation does not ensure that the changes are effective, or that they are approved by the user departments.

A maturity model for a technology organization is a tool that measures the progress and capability of the IT function in relation to its goals, processes, and practices. A maturity model can help identify gaps and areas for improvement, as well as benchmark the IT function against industry standards or best practices. One of the key aspects of a maturity model is the definition and clarity of roles and responsibilities for the IT function and its stakeholders. A roles and responsibility matrix, such as a RACI matrix, is a document that clarifies who is responsible, accountable, consulted, and informed for each task or deliverable in a project or process. A roles and responsibility matrix can help avoid confusion, duplication, or omission of work, as well as ensure accountability and communication among the IT function and its customers, partners, and suppliers. Therefore, an IS auditor should focus on reviewing the roles and responsibility matrix when evaluating the maturity model for a technology organization.

A standard operating procedure (SOP) is a document that describes the steps and instructions for performing a routine or repetitive task or process. SOPs are important for ensuring consistency, quality, and compliance in the IT function, but they are not directly related to the maturity model. A service level agreement (SLA) is a contract that defines the expectations and obligations between an IT service provider and its customers. SLAs are important for ensuring customer satisfaction, performance measurement, and dispute resolution in the IT function, but they are not directly related to the maturity model. A business resiliency plan is a document that outlines how an IT function will continue to operate or recover from a disruption or disaster. Business resiliency is important for ensuring availability, reliability, and security in the IT function, but it is not directly related to the maturity model. References: 1: Maturity Models for IT & Technology | Splunk 2: Responsibility assignment matrix - Wikipedia 3: Roles and Responsibilities Matrix - SDLCforms

The best control to minimize the risk of unauthorized access to lost company-owned mobile devices is device encryption. Device encryption is a process that transforms data on a device into an unreadable format using a cryptographic key. Device encryption protects the data stored on the device from being accessed by unauthorized parties, even if they bypass the password or PIN protection. Device encryption can also prevent data leakage if the device is disposed of or recycled without proper data sanitization. Password or PIN protection is a basic control that prevents unauthorized access to the device by requiring a secret code or pattern to unlock it. However, password or PIN protection can be easily compromised by brute force attacks, shoulder surfing, or social engineering. Device tracking software is a tool that allows the device owner or administrator to locate, lock, or wipe the device remotely in case of loss or theft. However, device tracking software depends on the device’s network connectivity and GPS functionality, which may not be available or reliable in some situations. Periodic backup is a process that copies the data from the device to another storage location for recovery purposes. Periodic backup can help restore the data in case of loss or damage of the device, but it does not prevent unauthorized access to the data on the device itself. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.4: Mobile Devices

 The best option to support the organization’s objectives of protecting data confidentiality while transporting data is encryption. Encryption is a process of transforming data into an unreadable form using a secret key or algorithm, so that only authorized parties can access the original data. Encryption protects the confidentiality of data in transit by preventing unauthorized interception, modification, or disclosure of the data. Encryption can also help comply with data privacy and security regulations, such as the GDPR and HIPAA.

The other options are not as effective as encryption in protecting data confidentiality while transporting data. Cryptographic hashes are mathematical functions that generate a fixed-length output from an input, but they do not encrypt the data. Hashes are used to verify the integrity and authenticity of data, but they do not prevent unauthorized access to the data. Virtual local area network (VLAN) is a logical grouping of network devices that share the same broadcast domain, but they do not encrypt the data. VLANs can improve network performance and security by isolating traffic, but they do not protect the data from being intercepted or modified by external attackers. Dedicated lines are physical connections that provide exclusive access to a network or service, but they do not encrypt the data. Dedicated lines can offer higher bandwidth and reliability, but they do not guarantee the confidentiality of the data from being compromised by physical tampering or eavesdropping.

The most important thing for an IS auditor to validate when auditing network device management is that all devices have current security patches assessed. This is because security patches are essential for fixing known vulnerabilities and preventing unauthorized access, data breaches, or denial-of-service attacks on the network devices. If the network devices are not patched regularly, they may expose the network to various cyber threats and compromise the confidentiality, integrity, and availability of the network services and data12.

Devices cannot be accessed through service accounts is not the most important thing to validate because service accounts are typically used for automated tasks or processes that require privileged access to network devices. Service accounts can be secured by using strong passwords, limiting their permissions, and monitoring their activities. However, service accounts alone do not protect the network devices from external or internal attacks that exploit unpatched vulnerabilities3.

Backup policies include device configuration files is not the most important thing to validate because backup policies are mainly used for restoring the network devices in case of failure, disaster, or corruption. Backup policies can help with recovering the network functionality and data, but they do not prevent the network devices from being compromised or attacked in the first place. Backup policies should be complemented by security policies that ensure the network devices are patched and protected4.

All devices are located within a protected network segment is not the most important thing to validate because network segmentation is a technique that divides the network into smaller subnets or zones based on different criteria, such as function, security level, or access control. Network segmentation can help isolate and contain the impact of a potential attack on a network device, but it does not prevent the attack from happening. Network segmentation should be combined with security patching and other security measures to ensure the network devices are secure.

A backlog consumption report is a report that shows the amount of work that has been completed and the amount of work that remains to be done in a project. It is a useful tool for measuring the progress and performance of a web-based customer service application development project, as it can indicate whether the project is on track, ahead or behind schedule, and how much effort is required to finish the project. A backlog consumption report can also help identify any issues or risks that may affect the project delivery. Critical path analysis reports, developer status reports and change management logs are also helpful for evaluating a project, but they are not as helpful as a backlog consumption report, as they do not provide a clear picture of the overall project status and completion rate. References:

 A primary responsibility of an IT steering committee is prioritizing IT projects in accordance with business requirements, as this ensures that IT resources are allocated to support the strategic objectives and needs of the organization. Reviewing periodic IT risk assessments, validating and monitoring the skill sets of IT department staff, and establishing IT budgets for the business are important activities, but they are not the primary responsibility of an IT steering committee. They may be delegated to other IT governance bodies or functions within the organization. References: CISA Review Manual (Digital Version), Chapter 1: Information Systems Auditing Process, Section 1.2: IT Governance

The concept of materiality is most important for an IS auditor to apply when planning an audit engagement, because it helps the auditor to determine the scope, objectives, procedures and resources of the audit. Materiality is the degree to which an omission or misstatement of information could affect the users’ decisions or the achievement of the audit objectives. By applying the concept of materiality, the auditor can focus on the most significant and relevant areas of the audit and avoid wasting time and effort on trivial or immaterial matters. The other options are not as important as planning an audit engagement, because they are either based on or affected by the materiality assessment done during the planning phase. References:

ISACA, CISA Review Manual, 27th Edition, chapter 1, section 1.31

ISACA, IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 12022

The lack of system documentation should be of most concern to an IS auditor reviewing the information systems acquisition, development, and implementation process. This is because system documentation is a vital source of information that describes the system’s purpose, functionality, design, architecture, testing, deployment, operation, and maintenance. System documentation helps the IS auditor to understand and evaluate the system’s quality, performance, security, compliance, and alignment with the business requirements and objectives. Without system documentation, the IS auditor may not be able to perform a thorough and effective audit of the system, as well as identify any issues or risks that may affect the system’s reliability or integrity12.

Data owners are not trained on the use of data conversion tools is not the most concerning issue, although it may indicate a lack of user readiness or competence for the system implementation. Data conversion tools are software applications that help users to transform data from one format or structure to another, such as from legacy systems to new systems. Data owners are users who have the responsibility and authority to manage and control the data within their domain. Data owners should be trained on how to use data conversion tools to ensure that the data is accurately and securely transferred to the new system, as well as to avoid any data loss, corruption, or inconsistency. However, data owners are not the only users who need training for the system implementation, and data conversion tools are not the only tools that need training34.

A post-implementation lessons-learned exercise was not conducted is not the most concerning issue, although it may indicate a lack of continuous improvement or learning culture for the system development and implementation process. A post-implementation lessons-learned exercise is a meeting or a session that takes place after the completion of a system implementation project, where the project team and stakeholders discuss and document the successes and failures of the project, as well as identify any best practices or areas for improvement for future projects. A post-implementation lessons-learned exercise can help to enhance the project management skills, knowledge, and performance of the project team and stakeholders, as well as to avoid repeating the same mistakes or problems in future projects56.

System deployment is routinely performed by contractors is not the most concerning issue, although it may pose some challenges or risks for the system implementation process. System deployment is the final stage of the system development life cycle (SDLC), where the system is installed and configured on the target environment and made available for use by end-users. System deployment can be performed by internal staff or external contractors, depending on the availability, expertise, and cost of resources. System deployment by contractors may offer some benefits such as faster delivery, lower cost, or higher quality than internal staff. However, system deployment by contractors may also introduce some risks such as loss of control, dependency, or security breaches over the system implementation process

The answer D is correct because the most important thing to determine when conducting an audit of an organization’s data privacy practices is whether the systems inventory containing personal data is maintained. A systems inventory is a list of all the systems, applications, databases, and devices that store, process, or transmit personal data within the organization. Maintaining a systems inventory is essential for data privacy because it helps the organization to identify, classify, and protect the personal data it holds, as well as to comply with the relevant privacy laws and regulations. A systems inventory also enables the organization to perform data protection impact assessments (DPIAs), data breach notifications, data subject access requests, and data retention and disposal policies.

The other options are not as important as option D. Whether a disciplinary process is established for data privacy violations (option A) is a policy issue that may deter or sanction the employees who violate the data privacy rules, but it does not directly affect the data privacy practices of the organization. Whether strong encryption algorithms are deployed for personal data protection (option B) is a technical issue that may enhance the security and confidentiality of the personal data, but it does not address the other aspects of data privacy, such as accuracy, consent, and purpose limitation. Whether privacy technologies are implemented for personal data protection (option C) is also a technical issue that may support the data privacy practices of the organization, but it does not guarantee that the organization follows the best practices or complies with the applicable laws and regulations.

A balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The other options are not the primary uses of a balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy.

An IS auditor’s primary concern would be whether the recovery site devices can handle the storage requirements. The storage requirements are determined by the amount and type of data that needs to be backed up and restored in case of a disaster at the primary data center. The recovery site devices should have enough capacity, performance, reliability, and compatibility to meet these requirements.

If the recovery site devices cannot handle the storage requirements, then there is a risk that some data may not be backed up properly or may not be available for recovery when needed. This could result in data loss, corruption, or inconsistency, which could affect the business continuity and integrity of the organization.

Therefore, an IS auditor should verify that:

The recovery site devices have sufficient storage space to accommodate all the data that needs to be backed up from the primary data center.

The recovery site devices have adequate bandwidth and speed to transfer and access data efficiently and effectively.

The recovery site devices have appropriate security features and controls to protect data from unauthorized access or modification.

The recovery site devices are compatible with the primary data center devices in terms of hardware, software, format, and protocol.

An audit universe is a comprehensive list of all the auditable entities, processes, and activities within an organization. It helps the IS auditor to identify the scope, objectives, and priorities of the audit plan, as well as the resources and methodologies required to conduct the audits. An audit universe can also help the IS auditor to ensure that all the key risks, controls, and regulations are covered by the audit plan, and that there are no gaps or overlaps in the audit coverage.

The first activity that the IS auditor should perform when preparing a plan for audits to be carried out over a specified period is to determine the audit universe. This involves defining the criteria and methods for identifying and categorizing the auditable units, such as by business function, process, system, location, or risk level. The IS auditor should also consult with the management and other stakeholders to obtain their input and expectations for the audit plan. The IS auditor should then document and validate the audit universe, and update it regularly to reflect any changes in the organization’s structure, operations, or environment.

The other three activities are also important for preparing an audit plan, but they should be performed after determining the audit universe. Allocating audit resources involves assigning staff, time, budget, and tools to each audit based on their complexity, priority, and availability. Prioritizing risks involves assessing the likelihood and impact of each risk associated with each auditable unit, and ranking them according to their significance and urgency. Reviewing prior audit reports involves analyzing the findings, recommendations, and actions from previous audits related to each auditable unit, and evaluating their current status and relevance.

Therefore, determining the audit universe is the best answer.

 Recounting the transaction records to ensure no records are missing provides assurance that the best transactions were recovered successfully from a snapshot copy. This is because recounting the transaction records can verify that the number of records in the restored database matches the number of records in the snapshot copy, which represents the state of the database before the deletion occurred. Recounting the transaction records can also detect any data corruption or inconsistency that may have occurred during the restore process1.

Reviewing transaction recovery logs to ensure no errors were recorded is not the best answer, because transaction recovery logs may not capture all the details or issues that may affect the data quality or integrity. Transaction recovery logs are mainly used to monitor and troubleshoot the restore process, but they may not reflect the actual content or accuracy of the restored data2.

Rerunning the process on a backup machine to verify the results are the same is not the best answer, because rerunning the process may introduce additional errors or inconsistencies that may affect the data quality or integrity. Rerunning the process may also consume more time and resources than necessary, and it may not guarantee that the results are identical to the original data3.

Comparing transaction values against external statements to verify accuracy is not the best answer, because external statements may not be available or reliable for all transactions. External statements are documents or reports that provide information about transactions from a third-party source, such as a bank, a vendor, or a customer. However, external statements may not cover all transactions, or they may have different formats, standards, or timeliness than the internal data

The best way to detect unauthorized copies of licensed software on systems is to conduct periodic software scanning. Software scanning is a process of using specialized tools or programs to scan the systems and identify the software installed, the license status, the usage, and the compliance with the software policies and agreements. Software scanning can help to detect any unauthorized, unlicensed, or illegal copies of software on the systems, as well as any discrepancies or violations of the software licenses. Software scanning can also help to optimize the software inventory, reduce the software costs, and improve the security and performance of the systems12.

Some examples of software scanning tools are:

Microsoft Software Inventory Analyzer (MSIA): A free tool that scans Windows-based computers and servers and generates reports on the Microsoft products installed, such as operating systems, applications, and updates3.

Belarc Advisor: A free tool that scans Windows-based computers and generates reports on the hardware and software installed, including license keys, versions, usage, and security status4.

Lansweeper: A paid tool that scans Windows, Linux, Mac, and other network devices and generates reports on the hardware and software inventory, license compliance, configuration, and vulnerabilities5.

To conduct periodic software scanning, you need to:

Choose a suitable software scanning tool that meets your needs and budget.

Define the scope and frequency of the software scanning, such as which systems to scan, how often to scan, and what information to collect.

Configure and run the software scanning tool according to the instructions and settings.

Review and analyze the software scanning reports and identify any unauthorized copies of licensed software on the systems.

Take appropriate actions to remove or regularize the unauthorized copies of licensed software on the systems.

Document and report the results and findings of the software scanning.

The best source of information for examining the classification of new data is the risk assessment results, because they provide an objective and consistent basis for determining the value, sensitivity, and criticality of the data, as well as the potential impact of unauthorized disclosure, modification, or loss of the data12. The risk assessment results can help to define the appropriate classification levels and criteria for the data, such as public, internal, confidential, or restricted12. Input by data custodians, security policy requirements, and current level of protection are not the best sources of information for examining the classification of new data, because they may not reflect the actual risk exposure or business needs of the data. References: 1: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.2 2: CISA Online Review Course, Module 5, Lesson 4

 The primary purpose of obtaining a baseline image during an operating system audit is to identify atypical running processes. A baseline image is a snapshot of the normal state and configuration of an operating system, including the processes that are expected to run on it. By comparing the current state of the operating system with the baseline image, an IS auditor can detect any deviations or anomalies that may indicate unauthorized or malicious activity, such as malware infection, privilege escalation, or data exfiltration. A baseline image can also help an IS auditor to assess the performance and efficiency of the operating system, as well as its compliance with security standards and policies.

Verifying antivirus definitions (option B) is not the primary purpose of obtaining a baseline image, although it may be a part of the baseline configuration. Antivirus definitions are the files that contain the signatures and rules for detecting and removing malware. An IS auditor may verify that the antivirus definitions are up to date and consistent across the operating system, but this does not require obtaining a baseline image.

Identifying local administrator account access (option C) is not the primary purpose of obtaining a baseline image, although it may be a part of the baseline configuration. Local administrator accounts are user accounts that have full control over the operating system and its resources. An IS auditor may identify and review the local administrator accounts to ensure that they are properly secured and authorized, but this does not require obtaining a baseline image.

Verifying the integrity of operating system backups (option D) is not the primary purpose of obtaining a baseline image, although it may be a part of the backup process. Operating system backups are copies of the operating system data and settings that can be used to restore the system in case of failure or disaster. An IS auditor may verify that the operating system backups are complete, accurate, and accessible, but this does not require obtaining a baseline image.

 The finding that should be of greatest concern to an IS auditor reviewing data conversion and migration during the implementation of a new application system is that unauthorized data modifications occurred during conversion. Data conversion and migration is a process that involves transferring data from one system to another, ensuring its accuracy, completeness, integrity, and usability. Unauthorized data modifications during conversion can result in data loss, corruption, inconsistency, or duplication, which can affect the functionality, performance, reliability, and security of the new system. Unauthorized data modifications can also have serious business implications, such as affecting decision making, reporting, compliance, customer service, and revenue. The IS auditor should verify that adequate controls are in place to prevent, detect, and correct unauthorized data modifications during conversion, such as access control, data validation, reconciliation, audit trail, and backup and recovery. The other findings (A, B and D) are less concerning, as they can be mitigated by documenting the change management process, restoring the backups of the old system and data from offline storage, or automating the data conversion process. References: CISA Review Manual (Digital Version), Chapter 3: Information Systems Acquisition, Development & Implementation, Section 3.4: System Implementation

 The auditor should first escalate to audit management to discuss the audit plan. This is because the audit plan should be based on a risk assessment and aligned with the organization’s objectives and strategies. The auditor should not accept the CIO’s request without proper justification and approval from the audit management, who are responsible for ensuring the audit plan’s quality and independence. The auditor should also communicate the potential risks and implications of not conducting IS audits in the upcoming year, such as missing new or emerging threats, vulnerabilities, or compliance issues. References:

Following a breach, the maximum amount of time before customers must be notified that their personal information may have been compromised depends on the industry regulations that apply to the organization. Different industries and jurisdictions may have different legal and regulatory requirements for breach notification, such as the General Data Protection Regulation (GDPR) in the European Union, the Health Insurance Portability and Accountability Act (HIPAA) in the United States, or the Personal Information Protection and Electronic Documents Act (PIPEDA) in Canada. Industry standards, incident response plans, and information security policies are not as authoritative as industry regulations in determining the breach notification time frame. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

Function point analysis (FPA) is the best methodology to use for estimating the complexity of developing a large business application. FPA is a technique that measures the functionality of a software system based on the user requirements and the business processes that the system supports. FPA assigns a numerical value to each function or feature of the system, based on its type, complexity, and relative size. The total number of function points represents the size and complexity of the system, which can be used to estimate the development effort, cost, and time.

FPA has several advantages over other estimation methods, such as:

It is independent of the technology, programming language, or development methodology used for the system. Therefore, it can be applied consistently across different platforms and environments.

It is based on the user perspective and the business value of the system, rather than the technical details or implementation aspects. Therefore, it can be performed early in the project life cycle, before the design or coding phases.

It is objective and standardized, as it follows a set of rules and guidelines defined by the International Function Point Users Group (IFPUG). Therefore, it can reduce ambiguity and improve accuracy and reliability of the estimates.

It is adaptable and scalable, as it can handle changes in the user requirements or the system scope. Therefore, it can support agile and iterative development approaches.

This means that the IT investments are aligned with the strategic goals and priorities of the organization, and that they deliver value and benefits to the business. Mapping IT investments to specific business objectives can help ensure that the IT investments are relevant, justified, and measurable, and that they support the organization’s mission and vision.

IT investments are implemented and monitored following a system development life cycle (SDLC) is an indication of effective IT project management, but not necessarily of effective IT investment management. The SDLC is a framework that guides the development and implementation of IT systems and applications, but it does not address the alignment, justification, or measurement of the IT investments.

Key performance indicators (KPIs) are defined for each business requiring IT investment is an indication of effective IT performance management, but not necessarily of effective IT investment management. KPIs are metrics that measure the outcomes and results of IT activities and processes, but they do not address the alignment, justification, or value of the IT investments.

The IT investment budget is significantly below industry benchmarks is not an indication of effective IT investment management, but rather of low IT spending. The IT investment budget should be based on the organization’s needs and capabilities, and not on external comparisons. A low IT investment budget may indicate that the organization is underinvesting in IT, which could limit its potential for growth and innovation.

Due professional care is the obligation of an IS auditor to exercise the appropriate level of skill, competence, and diligence in performing an audit. It also requires the IS auditor to comply with the relevant standards, guidelines, and ethical principles of the profession. Completing an engagement by email only may compromise due professional care, as it may limit the IS auditor’s ability to obtain sufficient and appropriate evidence, to communicate effectively with the auditee and other stakeholders, and to perform adequate quality assurance and review procedures. The other options are not as relevant as due professional care, as they relate to specific aspects of an audit, such as proficiency (the knowledge and skills of the IS auditor), sufficient evidence (the quantity and quality of the audit evidence), and reporting (the presentation and communication of the audit results). References: CISA Review Manual (Digital Version), Domain 1: The Process of Auditing Information Systems, Section 1.2 ISACA IT Audit and Assurance Standards

 The best way to help ensure new IT implementations align with enterprise architecture (EA) principles and requirements is to conduct EA reviews as part of the change advisory board (CAB). A CAB is a committee that evaluates and authorizes changes to IT services, such as new IT implementations. By conducting EA reviews as part of the CAB process, the organization can ensure that the proposed changes are consistent with the EA vision, goals, standards, and guidelines. This can help avoid potential conflicts, risks, or inefficiencies that may arise from misaligned IT implementations. Additionally, EA reviews can help identify opportunities for improvement, optimization, or innovation in the IT services.

The other options are not the best ways to help ensure new IT implementations align with EA principles and requirements. Documenting the security view as part of the EA is important, but it does not guarantee that new IT implementations will follow the security requirements or best practices. Considering stakeholder concerns when defining the EA is also essential, but it does not ensure that new IT implementations will meet the stakeholder expectations or needs. Performing mandatory post-implementation reviews of IT implementations is a good practice, but it does not prevent potential issues or problems that may arise from misaligned IT implementations.

Post-implementation testing is the process of verifying and validating the functionality, performance, and security of a system after it has been deployed to the production environment1. Post-implementation testing is important for ensuring that the system meets the user requirements and expectations, as well as the operational and business objectives. Post-implementation testing also helps to identify and resolve any defects, errors, or issues that may have occurred during the deployment process or that may have been missed during the previous testing stages2.

Therefore, the observation that post-implementation testing is not conducted for all system releases should be of greatest concern to an IS auditor performing an audit of change and release management controls for a new complex system developed by a small in-house IT team. This observation indicates that the system may have quality, reliability, or security problems that could affect the user satisfaction, system performance, or data integrity. This observation also suggests that the change and release management controls are not adequate or effective, as they do not ensure that all system releases are properly tested and validated before and after deployment.

Option A is not correct because access to change testing strategy and results is not restricted to staff outside the IT team is not a major concern for an IS auditor. While it is good practice to limit access to sensitive or confidential information, such as test data or test cases, to authorized personnel only, access to change testing strategy and results may not pose a significant risk to the system or the organization. Moreover, access to change testing strategy and results may be beneficial for some stakeholders outside the IT team, such as business users, project managers, or auditors, who may need to review or evaluate the testing process or outcomes.

Option B is not correct because some user acceptance testing (UAT) was completed by members of the IT team is not a major concern for an IS auditor. User acceptance testing is the process of verifying and validating that the system meets the user requirements and expectations by involving actual or representative users in the testing process3. While it is preferable to have independent and unbiased users perform UAT, it may not be feasible or practical for some organizations, especially those with small or limited resources. Therefore, some UAT may be completed by members of the IT team, as long as they have sufficient knowledge and experience of the user needs and expectations, and as long as they follow the UAT plan and criteria.

Option C is not correct because IT administrators have access to the production and development environment is not a major concern for an IS auditor. IT administrators are responsible for managing and maintaining the IT infrastructure, including the production and development environments4. Therefore, it is reasonable and necessary for them to have access to both environments, as long as they follow the appropriate policies and procedures for accessing, using, and securing them. Moreover, IT administrators may need to perform tasks such as backup, restore, patching, or troubleshooting in both environments.

 Scope creep is the uncontrolled expansion of a project’s scope, which can result in delays, cost overruns, and quality issues. To mitigate the risk of scope creep, an IS auditor should look for project change management controls, which are processes and procedures for managing changes to the project’s scope, schedule, budget, and quality. Project change management controls ensure that changes are properly requested, approved, documented, communicated, and implemented. Source code version control, existence of an architecture review board, and configuration management are also important for software development, but they do not directly address the risk of scope creep. References: ISACA Frameworks: Blueprints for Success, Project Management Institute: A Guide to the Project Management Body of Knowledge

The most critical factor for the success of an information security program is management’s commitment to information security. Management’s commitment to information security means that the senior management supports, sponsors, funds, monitors and enforces the information security program within the organization. Management’s commitment to information security also demonstrates leadership, sets the tone and culture, and establishes the strategic direction and objectives for information security. User accountability for information security, alignment of information security with IT objectives, and integration of business and information security are also important factors for the success of an information security program, but they are not as critical as management’s commitment to information security, as they depend on or derive from it. References: Info Technology & Systems Resources | COBIT, Risk, Governance … - ISACA, IT Governance and Process Maturity

The greatest concern with the lack of structure for technology risk governance is C. Key decision-making entities for technology risk have not been identified. Technology risk governance is the process of establishing and maintaining the policies, roles, responsibilities, and accountabilities for managing technology risks within an organization1. Technology risk governance requires a clear organizational structure that defines who has the authority and responsibility to make decisions, set objectives, allocate resources, monitor performance, and ensure compliance for technology risk management2. Without such a structure, an organization may face the following challenges:

Lack of alignment and integration between technology and business strategies, leading to suboptimal outcomes and missed opportunities.

Lack of clarity and consistency in technology risk identification, assessment, mitigation, and reporting, leading to gaps and overlaps in risk coverage and exposure.

Lack of communication and collaboration among different stakeholders involved in technology risk management, leading to conflicts and inefficiencies.

Lack of oversight and accountability for technology risk management activities and results, leading to poor quality and reliability.

The best tool for detailed testing of a business application’s data and configuration files is an audit analytics tool. An audit analytics tool is a software that helps auditors to analyze large sets of data and identify anomalies, trends, and patterns that are relevant to the audit objectives. An audit analytics tool can also provide audit evidence and support the auditor’s professional judgment and conclusions.

Some of the benefits of using an audit analytics tool are:

It can improve the efficiency and effectiveness of the audit by reducing the time and effort required to perform manual tests and procedures.

It can enhance the quality and reliability of the audit by increasing the coverage and accuracy of the data analysis and testing.

It can enable the auditor to perform more complex and sophisticated tests and procedures that may not be possible or feasible with traditional methods.

It can help the auditor to discover new insights and risks that may not be apparent or detectable with traditional methods.

Some examples of audit analytics tools are:

IDEA: A data analysis software that allows auditors to import, analyze, and visualize data from various sources and formats. It also offers features such as sampling, stratification, gap analysis, duplicate detection, Benford’s law, and regression analysis.1

ACL: A data analysis software that helps auditors to access, analyze, and report on data from various sources and formats. It also offers features such as sampling, stratification, gap analysis, duplicate detection, Benford’s law, regression analysis, and scripting.2

TeamMate Analytics: A data analysis software that integrates with Microsoft Excel and provides auditors with a range of tools and functions to perform data analysis and testing. It also offers features such as sampling, stratification, gap analysis, duplicate detection, Benford’s law, regression analysis, and scripting.3

 Management’s commitment to information security is the most critical factor for the success of an information security program, as it sets the tone and direction for the organization’s security culture and practices. Management’s commitment is demonstrated by establishing a clear security policy, providing adequate resources, assigning roles and responsibilities, enforcing compliance, and supporting continuous improvement. The other options are important elements of an information security program, but they depend on management’s commitment to be effective. References: CISA Review Manual (Digital Version) 1, page 439.

 A transaction processing system (TPS) is a system that captures, processes, and stores data related to business transactions1. A general ledger is a system that records the financial transactions of an organization in different accounts2. An interface is a connection point between two systems that allows data exchange3. A system fix is a change or update to a system that resolves a problem or improves its functionality4.

The IS auditor should recommend to perform periodic reconciliations to validate the interface between the TPS and the general ledger is working in the future. A reconciliation is a process of comparing and verifying the data in two systems to ensure accuracy and consistency1. By performing periodic reconciliations, the IS auditor can detect and correct any errors or discrepancies in the data, such as duplicate transactions, missing transactions, or incorrect amounts. This way, the IS auditor can ensure the reliability and integrity of the financial data in both systems.

The other options are not as effective as periodic reconciliations to validate the interface. System owner sign-off for the system fix is a form of approval that indicates the system owner agrees with the change and its expected outcome4. However, this does not guarantee that the system fix will work as intended or prevent future errors. Conducting functional testing is a process of verifying that the system performs its intended functions correctly and meets its requirements4. However, this is usually done before or after the system fix is implemented, not on an ongoing basis. Improving user acceptance testing (UAT) is a process of evaluating whether the system meets the needs and expectations of the end users4. However, this is also done before or after the system fix is implemented, not on an ongoing basis. Therefore, option A is the correct answer.

Aligning IT strategy with business strategy primarily helps an organization to optimize investments in IT. This is because alignment ensures that IT resources and capabilities are aligned with the business goals and priorities, and that IT delivers value to the business in terms of efficiency, effectiveness, innovation, and competitive advantage12. By aligning IT strategy with business strategy, an organization can avoid wasting money and time on IT projects or services that do not support or contribute to the business outcomes3. Alignment also helps to identify and prioritize the most critical and valuable IT initiatives that can create or optimize business value4.

Therefore, the correct answer to your question is A. optimize investments in IT.

The primary purpose of an incident response plan is to reduce the impact of an adverse event on information assets. An incident response plan is a set of instructions and procedures that guide the organization’s actions in the event of a security breach, cyberattack, or other disruption that affects its information systems and data. An incident response plan aims to:

Detect and identify the incident as soon as possible.

Contain and isolate the incident to prevent further damage or spread.

Analyze and investigate the incident to determine its cause, scope, and impact.

Eradicate and eliminate the incident and its root causes from the affected systems and data.

Recover and restore the normal operations and functionality of the systems and data.

Learn and improve from the incident by documenting the lessons learned, best practices, and recommendations for future prevention and mitigation.

By following an incident response plan, the organization can minimize the negative consequences of an adverse event on its information assets, such as:

Loss or corruption of data or information.

Disclosure or theft of confidential or sensitive data or information.

Interruption or degradation of system or service availability or performance.

Legal or regulatory noncompliance or liability.

Financial or reputational loss or damage.

An incident response plan also helps the organization to demonstrate its due diligence and accountability in protecting its information assets and complying with its legal and contractual obligations.

The other options are not the primary purpose of an incident response plan, although they may be secondary benefits or outcomes of having one.

Increasing the effectiveness of preventive controls is not the primary purpose of an incident response plan. Preventive controls are controls that aim to prevent or deter incidents from occurring in the first place, such as firewalls, antivirus software, encryption, authentication, etc. An incident response plan is a reactive control that deals with incidents after they have occurred. However, an incident response plan may help to improve the effectiveness of preventive controls by identifying and addressing their weaknesses or gaps.

Reducing the maximum tolerable downtime (MTD) of impacted systems is not the primary purpose of an incident response plan. MTD is a measure of how long an organization can tolerate a system or service outage before it causes unacceptable harm or loss to its business operations or objectives. An incident response plan may help to reduce the MTD of impacted systems by facilitating a faster and smoother recovery process. However, reducing the MTD is not the main goal of an incident response plan, but rather a desired outcome.

Increasing awareness of impacts from adverse events to IT systems is not the primary purpose of an incident response plan. Awareness is a state of being informed or conscious of something. An incident response plan may help to increase awareness of impacts from adverse events to IT systems by providing information and communication channels for stakeholders, such as management, employees, customers, regulators, etc. However, increasing awareness is not the main objective of an incident response plan, but rather a means to achieve other objectives, such as reducing impact, ensuring compliance, or maintaining trust.

Effective governance over IT infrastructure is indicated by the ability to deliver continuous, reliable performance12. This is because good governance ensures that IT investments support business objectives and produce measurable results towards achieving their strategies2. It involves implementing management and internal controls, strengthening security, financial controls, risk mitigation, and inspection and compliance obligations3. While security awareness programs, the number of servers, and the number of security incidents can be aspects of IT governance, they are not the best indicators of its effectiveness.

When identifying which servers are no longer required, reviewing server CPU usage trends is the most helpful approach. Monitoring the CPU usage over time provides insights into how actively a server is being utilized. Servers with consistently low CPU usage may be candidates for consolidation or decommissioning. By analyzing CPU utilization patterns, IT management can make informed decisions about which servers can be retired without impacting performance or availability1.

 The IS audit manager should specifically review the detailed evidence of the successes and weaknesses of all contingency testing to substantiate the conclusions of the audit of the corporate disaster recovery test. This is because the detailed evidence can provide the audit manager with a clear and objective picture of how well the disaster recovery plan was executed, what issues or gaps were encountered, and what recommendations or actions were taken to address them. The detailed evidence can also help the audit manager to verify the accuracy, completeness, and validity of the audit findings, as well as to evaluate the adequacy and effectiveness of the disaster recovery controls.

The other options are not as specific or relevant as the detailed evidence of all contingency testing. Overviews of interviews between data center personnel and the auditor may provide some useful information, but they are not sufficient to substantiate the conclusions without supporting evidence from the actual testing. Prior audit reports involving other corporate disaster recovery audits may provide some benchmarking or comparison data, but they are not directly related to the current audit scope and objectives. Summary memos reflecting audit opinions regarding noted weaknesses may provide some high-level insights, but they are not enough to substantiate the conclusions without detailed evidence to back them up.

Admin accounts typically have the highest level of privileges and access to sensitive data. If the passwords for these accounts are not set to expire, it increases the risk of unauthorized access and potential security breaches. This is especially true if an admin’s credentials are compromised, as the attacker could have ongoing access to critical systems and data1.

The greatest concern when reviewing an IT strategic plan is B. The plan does not support relevant organizational goals. This is because an IT strategic plan should align and integrate the IT goals and objectives with the organization’s overall strategy and vision, and ensure that IT supports and enables the business processes and functions1. If the IT strategic plan does not support relevant organizational goals, it may lead to:

Suboptimal or negative outcomes and value for the organization, as IT investments and initiatives may not align with the organization’s priorities, needs, or expectations1.

Conflicts or inconsistencies between IT and business functions, as IT may not deliver the expected level of service, quality, or performance2.

Wasted or inefficient use of resources, as IT may spend time, money, or effort on projects or activities that are not relevant or beneficial for the organization2.

The best evidence to determine whether transactions have been executed by authorized employees is audit trails. Audit trails are secure records that catalog events or procedures to provide support documentation. They are used to authenticate security and operational actions, mitigate challenges, or provide proof of compliance and operational integrity2. Audit trails can track and trace the following information related to transactions:

Who initiated, approved, modified, or deleted a transaction

When a transaction occurred (date and time)

Where a transaction took place (location or device)

What type of transaction was performed (action or operation)

Why a transaction was executed (purpose or reason)

By analyzing audit trails, an IS auditor can verify whether transactions have been executed by authorized employees or not. Audit trails can also identify any unauthorized, fraudulent, or erroneous transactions that may have occurred. Audit trails can also help to resolve any disputes or discrepancies that may arise from transactions.

Stress testing is designed to evaluate a system’s performance under extreme conditions1. It is typically carried out in a test environment that closely mirrors the production environment, using production workloads1. This approach ensures that the test results accurately reflect how the system would perform under similar conditions in the production environment1. Using a test environment also prevents any disruptions or damage to the production environment during testing1.

Data classification is the process of tagging data according to its type, sensitivity, and value to the organization. Data transformation is the process of changing the structure and format of data to make it usable for analysis and visualization. Both processes are important for data security and compliance, but they also pose some challenges.

One of the challenges is to ensure that the organization’s data classification policies are preserved during the process of data transformation. This means that the data should retain its original classification level and labels after it is transformed, and that the appropriate controls and protections are applied to the transformed data.

The best way to ensure this is to implement classification labels in metadata during data creation (D). Metadata is data that describes other data, such as its source, format, content, and context. By adding classification labels to metadata, the data can be easily identified and tracked throughout its lifecycle, including during data transformation. The labels can also help enforce the proper access rights and encryption standards for the data, regardless of its state or location.
