Top Tips for Passing the Isaca CISM Exam on Your First Try

The primary objective of performing a vulnerability assessment following a business system update is to review the effectiveness of controls. A vulnerability assessment is a systematic review of security weaknesses in an information system. It evaluates if the system is susceptible to any known vulnerabilities, assigns severity levels to those vulnerabilities, and recommends remediation or mitigation, if and whenever needed1. A business system update is a process of modifying or enhancing an information system to improve its functionality, performance, security, or compatibility. A business system update may introduce new features, fix bugs, patch vulnerabilities, or comply with new standards or regulations2. Performing a vulnerability assessment following a business system update is important because it helps to:

•Review the effectiveness of controls that are implemented to protect the information sys-tem from threats and risks

•Identify any new or residual vulnerabilities that may have been introduced or exposed by the update

•Evaluate the impact and likelihood of potential incidents that may exploit the vulnerabili-ties

•Prioritize and implement appropriate actions to address the vulnerabilities

•Verify and validate the security posture and compliance of the updated information sys-tem

Therefore, the primary objective of performing a vulnerability assessment following a business system update is to review the effectiveness of controls that are designed to ensure the confidentiality, integrity, and availability of the information system and its data. The other options are not the primary objectives of performing a vulnerability as-sessment following a business system update. Determining operational losses is not an objective, but rather a possible consequence of not performing a vulnerability as-sessment or not addressing the identified vulnerabilities. Improving the change control process is not an objective, but rather a possible outcome of performing a vulnerability assessment and incorporating its results and recommendations into the change man-agement cycle. Updating the threat landscape is not an objective, but rather a prereq-uisite for performing a vulnerability assessment that requires using up-to-date sources of threat intelligence and vulnerability information.

Process owners are the people who are responsible for the design, execution, and improvement of the business processes that support the organization’s objectives and operations. Process owners have the greatest importance in the development of an information security strategy, as they provide the input and feedback on the business requirements, expectations, and priorities that the information security strategy should address and support. Process owners also help to identify and assess the risks and impacts that the business processes face, and to define and implement the security controls and measures that can mitigate or reduce them. Process owners also facilitate the alignment and integration of the information security strategy with the business strategy, as well as the communication and collaboration among the various stakeholders and functions involved in the information security program. End users, security architects, and corporate auditors are all important stakeholders in the information security program, but they do not have the greatest importance in the development of an information security strategy. End users are the people who use the information systems and services that the information security program protects and enables. End users provide the input and feedback on the usability, functionality, and performance of the information systems and services, as well as the security awareness and behavior that they exhibit. Security architects are the people who design and implement the security architecture that supports the information security strategy. Security architects provide the input and feedback on the technical requirements, capabilities, and solutions that the information security strategy should leverage and optimize. Corporate auditors are the people who evaluate and verify the compliance and effectiveness of the information security program. Corporate auditors provide the input and feedback on the standards, regulations, and best practices that the information security strategy should follow and adhere to. Therefore, process owners have the greatest importance in the development of an information security strategy, as they provide the input and feedback on the business requirements, expectations, and priorities that the information security strategy should address and support. References = CISM Review Manual 2023, page 31 1; CISM Practice Quiz 2

Email software packages that provide native encryption of messages use proprietary algorithms and formats that are not compatible with other email software packages. This means that the encryption cannot interoperate across product domains, and the recipients of encrypted messages must use the same email software package as the sender to decrypt and read the messages. This limits the usability and scalability of native encryption, and may also pose security risks if the encryption algorithms or formats are not well-tested or widely accepted. A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains1234. References = CISM Review Manual 15th Edition, page 206. The Top 10 Email Encryption Solutions In 2023 - Expert Insights2, The Best Email Encryption Services for 2023 | PCMag3, The Top 12 Email Encryption Services for 2023 - Right Inbox4.

A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains. This means that emails sent from one product cannot be read by another product, as the encryption keys used are not compatible. This can be a problem when sending emails to people who use different software packages, as the encrypted emails cannot be read.

 Single sign-on (SSO) is a technology that allows users to access multiple applications or services with one set of credentials, such as a username and password. The primary advantage of SSO is that it increases the efficiency of access management, as it reduces the need for users to remember and enter multiple passwords for different applications or services. SSO also simplifies the user experience, as they can log in once and access multiple resources without having to switch between different windows or tabs. SSO can also improve the security of related applications, as it reduces the risk of password compromise or phishing attacks. However, SSO does not strengthen user passwords or support multiple authentication mechanisms by itself. It is a complementary technology that enhances the security and convenience of access management. References = CISM Review Manual, 16th Edition, page 991

The primary advantage of single sign-on (SSO) is that it increases the efficiency of access management. With SSO, users only need to remember one set of credentials to access all of their applications, rather than having to remember multiple usernames and passwords for each application. This simplifies the user experience and helps to reduce the amount of time spent managing access to multiple applications. Additionally, SSO can also increase the security of related applications, as users are not sharing the same credentials across multiple applications, and it can also support multiple authentication mechanisms, such as biometric authentication.

A risk owner is a person or entity that is responsible for ensuring that risk is managed effectively. One of the primary responsibilities of a risk owner is to implement controls that will help mitigate or manage the risk. While risk assessments, determining the organization's risk appetite, and monitoring control effectiveness are all important aspects of managing risk, it is the responsibility of the risk owner to take the necessary actions to manage the risk.

= The best way to enable the integration of information security governance into corporate governance is to establish an information security steering committee with business representation. An information security steering committee is a group of senior executives and managers from different business units and functions who are responsible for overseeing, directing, and supporting the information security program and strategy of the organization. An information security steering committee with business representation can enable the integration of information security governance into corporate governance by providing the following benefits12:

Align the information security objectives and priorities with the business objectives and priorities, and ensure that the information security program and strategy support and enable the achievement of the organizational goals and performance.

Communicate and promote the value and importance of information security to the board of directors, senior management, and other stakeholders, and ensure that information security is considered and incorporated in the decision making and planning processes of the organization.

Provide guidance and direction to the information security manager and the information security team, and ensure that they have the necessary authority, resources, and support to implement and maintain the information security program and strategy effectively and efficiently.

Monitor and evaluate the performance and outcomes of the information security program and strategy, and ensure that they are aligned with the expectations and requirements of the organization and its stakeholders, as well as the relevant laws, regulations, standards, and best practices.

Identify and address the issues, challenges, and opportunities related to information security, and ensure that the information security program and strategy are continuously improved and updated to reflect the changes and developments in the internal and external environment.

The other options are not the best way to enable the integration of information security governance into corporate governance, as they are less comprehensive, effective, or influential than establishing an information security steering committee with business representation. Well-documented information security policies and standards are important components of the information security program and strategy, but they are not sufficient to enable the integration of information security governance into corporate governance, as they may not reflect or align with the business needs, priorities, or expectations, and they may not be communicated, implemented, or enforced properly or consistently across the organization. Clear lines of authority across the organization are important factors for the information security governance structure, but they are not sufficient to enable the integration of information security governance into corporate governance, as they may not ensure the involvement, participation, or support of the senior executives, managers, and other stakeholders who are responsible for or affected by information security. Senior management approval of the information security strategy is an important outcome of the information security governance process, but it is not sufficient to enable the integration of information security governance into corporate governance, as it may not ensure the alignment, communication, or monitoring of the information security strategy with the business strategy, and it may not ensure the accountability, responsibility, or authority of the information security manager and the information security team12. References = CISM Domain 1: Information Security Governance (ISG) [2022 update], Information Security Governance for CISM® | Pluralsight, Aligning Information Security with Business Strategy - ISACA, Aligning Information Security with Business Objectives - ISACA

The disk hash value is a unique identifier that is calculated from the binary data of the disk. It is used to verify that the disk image is an exact copy of the original disk and that no changes have occurred during the acquisition or analysis process. The disk hash value is stored externally, such as on a CD-ROM or a USB drive, to prevent tampering or corruption. The disk hash value can also be used as evidence in court to prove the authenticity and reliability of the digital evidence123 References = 1: CISM Review Manual 15th Edition, ISACA, 2017, page 2532: Guide to Computer Forensics and Investigations Fourth Edition, page 4-103: Forensic disk acquisition over the network, Andrea Fortuna, 2018.The main purpose of creating and storing an external disk hash value when performing forensic data acquisition from a hard disk is to validate the integrity of the data during the analysis. This is done by comparing the original hash value of the disk to the hash value created during the acquisition process, which can be used to ensure that the data has not been tampered with or corrupted in any way. Additionally, by creating a hash value of the disk, it can be used to quickly verify the integrity of any data that is accessed from the disk in the future.

The explanation given in the manual is:

The information security manager’s knowledge of the business is the most critical factor for information security program success because it enables him or her to align security objectives with business goals and communicate effectively with senior management and other stakeholders. The other choices are important elements of an information security program but not as critical as the information security manager’s knowledge of the business.

An information security program is a set of policies, procedures, standards, guidelines, and tools that aim to protect an organization’s information assets from threats and ensure compliance with laws and regulations. An information security manager is a professional who oversees and coordinates the implementation and maintenance of an information security program. An information security manager should have a good understanding of the business environment, culture, strategy, processes, and needs of an organization to ensure that security supports its objectives.

A balanced scorecard is a tool that can be used to demonstrate the added value of an information security program by measuring and reporting on key performance indicators (KPIs) and key risk indicators (KRIs) aligned with strategic objectives. Security baselines, a gap analysis and a SWOT analysis are all useful for assessing and improving security posture, but they do not necessarily show how security contributes to business value.

 Reviewing the results of the vendor’s independent control reports is the best way to assess the risk associated with using a SaaS vendor because it provides an objective and reliable evaluation of the vendor’s security controls and practices. Independent control reports, such as SOC 2 or ISO 27001, are conducted by third-party auditors who verify the vendor’s compliance with industry standards and best practices. These reports can help the customer identify any gaps or weaknesses in the vendor’s security posture and determine the level of assurance and trust they can place on the vendor.

Verifying that information security requirements are included in the contract is a good practice, but it does not provide sufficient assurance that the vendor is actually meeting those requirements. The contract may also have limitations or exclusions that reduce the customer’s rights or remedies in case of a breach or incident.

Requesting customer references from the vendor is not a reliable way to assess the risk associated with using a SaaS vendor because the vendor may only provide positive or biased references that do not reflect the true experience or satisfaction of the customers. Customer references may also not have the same security needs or expectations as the customer who is conducting the assessment.

Requiring vendors to complete information security questionnaires is a useful way to gather information about the vendor’s security policies and procedures, but it does not provide enough evidence or verification that the vendor is actually implementing and maintaining those policies and procedures. Information security questionnaires are also subject to the vendor’s self-reporting and interpretation, which may not be accurate or consistent. References =

 The organization’s vision and mission should be the PRIMARY basis for an information security strategy, as they define the purpose and direction of the organization and its information security needs. A comprehensive gap analysis is a tool to identify the current state and desired state of information security, and the actions needed to close the gap. Information security policies are the high-level statements of management’s intent and expectations for information security, and are derived from the information security strategy. Audit and regulatory requirements are external factors that influence the information security strategy, but are not the primary basis for it. References = CISM Review Manual, 16th Edition, pages 17-181; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 782

The primary basis for an information security strategy should be the organization's vision and mission. The organization's vision and mission should be the foundation for the security strategy, and should inform and guide the security policies, procedures, and practices that are implemented. The results of a comprehensive gap analysis, information security policies, and audit and regulatory requirements should all be taken into consideration when developing the security strategy, but should not be the primary basis.

 = An identity and access management (IAM) system is a set of processes, policies, and technologies that enable an organization to manage the identities and access rights of its users across different systems and applications1. An IAM system can help an organization to comply with the government regulation by automating the provisioning and deprovisioning of user accounts, enforcing consistent access policies, and integrating different user directories2. An IAM system can also provide audit trails and reports to demonstrate compliance with the regulation3. A multi-factor authentication (MFA) system is a method of verifying the identity of a user by requiring two or more factors, such as something the user knows, has, or is4. An MFA system can enhance the security of user authentication, but it does not address the issue of removing user privileges from different systems within three days of termination. A privileged access management (PAM) system is a solution that manages and monitors the access of privileged users, such as administrators, to critical systems and resources. A PAM system can reduce the risk of unauthorized or malicious use of privileged accounts, but it does not solve the problem of managing the access of regular users across different systems. A governance, risk, and compliance (GRC) system is a software platform that integrates the functions of governance, risk management, and compliance management. A GRC system can help an organization to align its objectives, policies, and processes with the relevant regulations, standards, and best practices, but it does not directly enable the removal of user privileges from different systems within three days of termination. References = 1: CISM Review Manual (Digital Version), page 24 2: 1 3: 2 4: CISM Review Manual (Digital Version), page 25 : CISM Review Manual (Digital Version), page 26 : CISM Review Manual (Digital Version), page 27

 The information security manager’s first course of action should be to validate the relevance of the information received from the threat intelligence service. This means verifying the source, credibility, accuracy, and timeliness of the information, as well as assessing the potential impact and likelihood of the threat for the organization. This will help the information security manager to determine the appropriate response and prioritize the actions to mitigate the threat. Conducting an information security audit, performing a gap analysis, and informing senior management are possible subsequent actions, but they are not the first course of action. An information security audit is a systematic and independent assessment of the effectiveness of the information security controls and processes. A gap analysis is a comparison of the current state of the information security program with the desired state or best practices. Informing senior management is a communication activity that should be done after validating the information and assessing the risk. References = CISM Review Manual, 16th Edition, pages 44-451; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 632

The first step the information security manager should take upon learning of the potential threat is to validate the relevance of the information. This should involve researching the threat to evaluate its potential impact on the organization and to determine the accuracy of the threat intelligence. Once the information is validated, the information security manager can then take action, such as informing senior management, conducting an information security audit, or performing a gap analysis.

Reviewing the vendor contract should be the information security manager’s first course of action when discovering an HVAC vendor has remote access to the stores to enable real-time monitoring and equipment diagnostics. The vendor contract should specify the terms and conditions of the vendor’s access to the retailer’s network, such as the scope, purpose, duration, frequency, and method of access. The vendor contract should also define the roles and responsibilities of both parties regarding security, privacy, compliance, liability, and incident response. Reviewing the vendor contract will help the information security manager to understand the contractual obligations and expectations of both parties, and to identify any gaps or issues that need to be addressed or resolved1. The other options are not the first course of action for the information security manager when discovering an HVAC vendor has remote access to the stores. Conducting a penetration test of the vendor may be a useful way to assess the vendor’s security posture and potential vulnerabilities, but it should be done with the vendor’s consent and cooperation, and after reviewing the vendor contract2. Reviewing the vendor’s technical security controls may be a necessary step to verify the vendor’s compliance with security standards and best practices, but it should be done after reviewing the vendor contract and in accordance with the agreed-upon audit procedures3. Disconnecting the real-time access may be a drastic measure that could disrupt the vendor’s service delivery and violate the vendor contract, unless there is a clear and imminent threat or breach that warrants such action.

 The primary basis for determining the value of assets should be the business cost when assets are not available. This is because the value of assets is not only determined by their acquisition or replacement cost, but also by their contribution to the organization’s business objectives and processes. The business cost when assets are not available reflects the potential impact of losing or compromising the assets on the organization’s operations, performance, reputation, and compliance. The business cost when assets are not available can be estimated by conducting a business impact analysis (BIA), which identifies the criticality, dependencies, and recovery requirements of the assets. By using the business cost when assets are not available as the primary basis for determining the value of assets, the organization can prioritize the protection and management of the assets according to their importance and risk level. References = CISM Review Manual 15th Edition, page 64, page 65.
