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

The strongest justification for granting an exception to the security policy that disables access to USB storage devices on laptops and desktops is that the benefit is greater than the potential risk. A security policy is a document that defines the goals, objec-tives, principles, roles, responsibilities, and requirements for protecting information and systems in an organization. A security policy should be based on a risk assessment that identifies and evaluates the threats and vulnerabilities that affect the organiza-tion’s assets, as well as the potential impact and likelihood of incidents. A security pol-icy should also be aligned with the organization’s business objectives and risk appe-tite1. However, there may be situations where a security policy cannot be fully enforced or complied with due to technical, operational, or business reasons. In such cases, an exception to the policy may be requested and granted by an authorized person or body, such as a security manager or a policy committee. An exception to a security policy should be justified by a clear and compelling reason that outweighs the risk of non-compliance. An exception to a security policy should also be documented, approved, monitored, reviewed, and revoked as necessary2. The strongest justification for grant-ing an exception to the security policy that disables access to USB storage devices on laptops and desktops is that the benefit is greater than the potential risk. USB storage devices are portable devices that can store large amounts of data and can be easily connected to laptops and desktops via USB ports. They can provide several benefits for users and organizations, such as:

•Enhancing data mobility and accessibility

•Improving data backup and recovery

•Supporting data sharing and collaboration

•Enabling data encryption and authentication

However, USB storage devices also pose significant security risks for users and organi-zations, such as:

•Introducing malware or viruses to laptops and desktops

•Exposing sensitive data to unauthorized access or disclosure

•Losing or stealing data due to device loss or theft

•Violating security policies or regulations

Therefore, an exception to the security policy that disables access to USB storage de-vices on laptops and desktops should only be granted if the benefit of using them is greater than the potential risk of compromising them. For example, if a user needs to transfer a large amount of data from one laptop to another in a remote location where there is no network connection available, and the data is encrypted and protected by a strong password on the USB device, then the benefit of using the USB device may be greater than the risk of losing or exposing it. The other options are not the strongest justifications for granting an exception to the security policy that disables access to USB storage devices on laptops and desktops. Enabling USB storage devices based on user roles is not a justification, but rather a possible way of implementing a more gran-ular or flexible security policy that allows different levels of access for different types of users3. Users accepting the risk of noncompliance is not a justification, but rather a requirement for requesting an exception to a security policy that acknowledges their responsibility and accountability for any consequences of noncompliance4. Accessing being restricted to read-only is not a justification, but rather a possible control that can reduce the risk of introducing malware or viruses from USB devices to laptops and desktops5.

Data classification is the sole responsibility of the client organization when adopting a Software as a Service (SaaS) model. Data classification is the process of categorizing data based on its sensitivity, value and criticality to the organization. Data classification helps to determine the appropriate level of protection, access control and retention for different types of data. Data classification is an essential part of data governance and risk management, as it enables the organization to comply with legal and regulatory requirements, protect its intellectual property and reputation, and optimize its data storage and usage costs.

In a SaaS model, the client organization has the least control and responsibility over the cloud infrastructure, platform and application, as these are fully managed by the cloud service provider (CSP). The client organization only has control and responsibility over its own data and users. Therefore, the client organization is responsible for defining and implementing data classification policies and procedures, and ensuring that its data is properly labeled and handled according to its classification level. The client organization is also responsible for educating its users about the importance of data classification and the best practices for data security and privacy.

The other options are not the sole responsibility of the client organization in a SaaS model, as they are either shared with or delegated to the CSP. Host patching, penetration testing and infrastructure hardening are all related to the security and maintenance of the cloud infrastructure and platform, which are the responsibility of the CSP in a SaaS model. The CSP is expected to provide regular updates, patches and fixes to the host operating system, network and application components, and to conduct periodic security assessments and audits to identify and remediate any vulnerabilities or weaknesses in the cloud environment. The client organization may have some responsibility to monitor and verify the CSP’s performance and compliance with the service level agreement (SLA) and the cloud security standards and regulations, but it does not have direct control or access to the cloud infrastructure and platform. References =

 The primary purpose of business continuity and disaster recovery plans is to ensure that the organization can resume its critical business functions within the stated recovery time objectives (RTOs) after a disruptive event. RTOs are based on the business needs and the impact analysis of each function or process. Therefore, meeting the business needs is the best indicator that the plans are effective. Regulatory requirements, internal compliance requirements, and risk management objectives are important factors that influence the development and testing of the plans, but they are not the ultimate measure of their effectiveness. References = CISM Certified Information Security Manager Study Guide, Chapter 9: Business Continuity and Disaster Recovery, page 3071; CISM Foundations: Module 4 Course, Part Two: Business Continuity and Disaster Recovery Plans2; Imperva, Business Continuity & Disaster Recovery Planning (BCP & DRP)3

 A detailed incident notification process is most important to include in an incident response plan to ensure incidents are responded to by the appropriate individuals. The incident notification process defines the roles and responsibilities of the incident response team members, the escalation procedures, the communication channels, the reporting requirements, and the stakeholders to be informed. The incident notification process helps to ensure that the right people are involved in the incident response, that the incident is handled in a timely and efficient manner, and that the relevant information is shared with the appropriate parties. Skills required for the incident response team, a list of external resources to assist with incidents, and service level agreements (SLAs) are also important elements of an incident response plan, but they are not as critical as the incident notification process. Skills required for the incident response team describe the competencies and qualifications of the team members, but they do not specify who should be notified or involved in the incident response. A list of external resources to assist with incidents provides a directory of external parties that can provide support or expertise in the incident response, but it does not define the criteria or process for engaging them. Service level agreements (SLAs) define the expectations and obligations of the service providers and the service recipients in the incident response, but they do not detail the steps or procedures for notifying or escalating incidents. References = CISM Review Manual, 16th Edition, pages 191-1921; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 662

 Managed security solutions are services provided by external vendors that offer security expertise, resources, and tools to help organizations protect their information assets and systems. A primary benefit of managed security solutions is that they allow organizations to focus on their core business operations, while delegating the security tasks to the service provider. This can improve the efficiency and effectiveness of the organization, as well as reduce the complexity and cost of managing security internally. Managed security solutions can also provide a wider range of capabilities, easier implementation across an organization, and lower cost of operations, but these are not the primary benefits, as they may vary depending on the quality and scope of the service provider. References = CISM Review Manual, 16th Edition, ISACA, 2020, p. 841; CISM Online Review Course, Domain 3: Information Security Program Development and Management, Module 3: Information Security Program Management, ISACA2

According to the Certified Information Security Manager (CISM) Study Manual, risk owners are responsible for managing a risk, including taking corrective action to reduce the risk to an acceptable level. When implementing controls, it is essential to obtain input from risk owners to ensure that the controls are effective in managing the risk to an acceptable level.

By obtaining input from risk owners, the organization can ensure that the controls are tailored to the specific risks and are effective in reducing the risk to an acceptable level. This can help to minimize the impact of the risk on the organization and reduce the potential for financial or reputational damage.

 The main reason for having senior management review and approve an information security strategic plan is to ensure that the plan aligns with the corporate governance of the organization. Corporate governance is the set of responsibilities and practices exercised by the board and executive management to provide strategic direction, ensure objectives are achieved, manage risks appropriately and verify that the organization’s resources are used responsibly1. An information security strategic plan is a document that defines the vision, mission, goals, objectives, scope and approach for the information security program of the organization2. The plan should be aligned with the organization’s business strategy, risk appetite, culture, values and objectives3. By reviewing and approving the plan, senior management demonstrates their commitment and support for the information security program, ensures its alignment with the corporate governance, and provides the necessary resources and authority for its implementation4. References = 1: CISM Review Manual 15th Edition, ISACA, 2017, page 172: CISM Review Manual 15th Edition, ISACA, 2017, page 253: CISM Review Manual 15th Edition, ISACA, 2017, page 264: CISM Review Manual 15th Edition, ISACA, 2017, page 27.

Senior management review and approval of an information security strategic plan is important to ensure that the plan is aligned with the organization's overall corporate governance objectives. It is also important to ensure that the plan takes into account any legal and regulatory requirements, as well as the resources and staff needed to properly implement the plan.

An anomaly-based intrusion detection system (IDS) operates by gathering data on normal network behavior and using it as a baseline for measuring abnormal activity. This is important because it allows the IDS to detect any activity that is outside of the normal range of usage for the network, which can help to identify potential malicious activity or security threats. Additionally, the IDS will monitor for any changes in the baseline behavior and alert the administrator if any irregularities are detected. By contrast, signature-based IDSs operate by gathering attack pattern signatures from historical data and comparing them against incoming traffic in order to identify malicious activity.

 A business-aligned information security program is one that supports the organization’s business objectives and aligns the information security strategy with the business functions. A business impact analysis (BIA) is a process that identifies the critical business processes, assets, and functions of an organization, and assesses their potential impact in the event of a disruption or loss. A BIA helps to prioritize the information security requirements and controls that are needed to protect the organization’s critical assets and functions from various threats and risks. Therefore, a BIA is one of the most useful sources when planning a business-aligned information security program. References = CISM Review Manual 15th Edition, page 254; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 229.The most useful source when planning a business-aligned information security program is a Business Impact Analysis (BIA). A BIA is a process of identifying and evaluating the potential effects of disruptions to an organization's operations, and helps to identify the security controls and measures that should be implemented to reduce the impact of those disruptions. The BIA should include an assessment of the organization's information security posture, including its security policies, risk register, and enterprise architecture. With this information, organizations can develop an information security program that is aligned to the organization's business objectives.

 Performing a risk assessment is the best approach to determine how to protect newly acquired data assets prior to integration, as it will help to identify the threats, vulnerabilities, impacts, and likelihoods of the data assets, and to prioritize the appropriate risk treatment options. Including security requirements in the contract is a good practice, but it may not be sufficient to address the specific risks of the data assets. Assessing security controls and reviewing data architecture are also important steps, but they should be done after performing a risk assessment, as they will depend on the risk level and the risk app

The best approach to determine how to protect newly acquired data assets prior to integration is to perform a risk assessment. A risk assessment will identify the various threats and vulnerabilities associated with the data assets and help the organization develop an appropriate security strategy. This risk assessment should include an assessment of the security controls in place to protect the data, a review of the data architecture, and a review of any contractual requirements related to security.

The primary benefit of establishing a clear definition of a security incident is that it helps to develop effective escalation and response procedures. A security incident is an event or an attempt that disrupts or threatens the normal operations, security, or privacy of an organization’s information or systems1. A clear definition of a security in-cident helps to:

•Distinguish between normal and abnormal events, and between security-relevant and non-security-relevant events

•Determine the severity and impact of an incident, and the appropriate level of response

•Assign roles and responsibilities for incident detection, reporting, analysis, containment, eradication, recovery, and post-incident activities

•Establish criteria and thresholds for escalating incidents to higher authorities or external parties

•Define the communication channels and protocols for incident notification and coordina-tion

•Document the incident response process and procedures in a formal plan

According to NIST, a clear definition of a security incident is one of the key compo-nents of an effective incident response capability2. The other options are not the prima-ry benefits of establishing a clear definition of a security incident. Communicating the incident response process to stakeholders is important, but it is not the main purpose of defining a security incident. Adequately staffing and training incident response teams is essential, but it depends on other factors besides defining a security inci-dent. Making tabletop testing more effective is a possible outcome, but not a direct benefit of defining a security incident. References: 2: NIST SP 800-61 Rev. 2 Computer Security Incident Handling Guide 1: NIST Glossary - Security Incident : What is a securi-ty incident? - TechTarget : 10 types of security incidents and how to handle them - TechTarget : 45 CFR § 164.304 - Definitions - Electronic Code of Federal Regulations

The BEST indication that an organization has a mature information security culture is when its staff consistently consider risk in making decisions. When an organization's staff understands the risks associated with their actions and are empowered to make risk-informed decisions, it indicates that the organization has a mature information security culture.

According to the Certified Information Security Manager (CISM) Study Manual, "A mature information security culture exists when the people within the organization understand and appreciate the risks associated with information and technology and when they take steps to manage those risks on a daily basis."

While information security training, documented information security policies, and regular interaction between the chief information security officer (CISO) and the board are all important components of a mature information security culture, they are not sufficient on their own. It is only when staff consistently consider risk in making decisions that an organization's information security culture can be considered mature.

Assessing the consequences of noncompliance is the next step that should be done after determining that there are a significant number of exceptions to a newly released industry-required security standard. The information security manager should evaluate the potential impact and exposure of the organization due to the noncompliance with the security standard. The assessment should consider the legal, regulatory, contractual, and reputational implications of the noncompliance, as well as the likelihood and severity of the incidents or penalties that may result from the noncompliance. The assessment should also compare the cost and benefit of complying with the security standard versus accepting the risk of noncompliance. The assessment should provide the basis for making informed and rational decisions about how to address the noncompliance issue and prioritize the actions and resources needed to achieve compliance. Documenting risk acceptances, revising the organization’s security policy, and conducting an information security audit are all possible actions that may be taken to address the noncompliance issue, but they are not the next steps that should be done. These actions should be performed after assessing the consequences of noncompliance, and based on the results and recommendations of the assessment. Documenting risk acceptances may be appropriate if the organization decides to accept the risk of noncompliance, and if the risk is within the risk appetite and tolerance of the organization. Revising the organization’s security policy may be necessary if the organization decides to comply with the security standard, and if the policy needs to be updated to reflect the new requirements and expectations. Conducting an information security audit may be useful if the organization wants to verify the level of compliance and identify the gaps and weaknesses in the security controls and processes. Therefore, assessing the consequences of noncompliance is the next step that should be done after determining that there are a significant number of exceptions to a newly released industry-required security standard, as it helps the information security manager to understand the risk and impact of the noncompliance and to make informed and rational decisions about how to address it. References = CISM Review Manual 2023, page 43 1; CISM Practice Quiz 2

During the initiation phase of the system development life cycle (SDLC) for a software project, information security activities should address security objectives, which are derived from the business objectives and the risk assessment. Security objectives define the desired level of protection for the system and its data, and guide the selection of security controls in later phases. Baseline security controls are predefined sets of security requirements that apply to common types of systems or environments. Benchmarking security metrics is a process of comparing the performance of security processes or controls against a standard or best practice. Cost-benefit analyses are used to evaluate the feasibility and effectiveness of security controls, and are usually performed in the acquisition/development phase or the implementation phase of the SDLC. References = CISM Review Manual, 16th Edition, page 1021; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 772

The explanation given is: “A BIA is a process that identifies and evaluates the potential effects of natural and man-made events on business operations. It helps to understand how critical systems are interrelated and what their dependencies are. A BIA also helps to determine the RTOs for each system. The other options are not directly related to understanding the relationships between critical systems.”
