Answer : B

The greatest benefit of information asset classification is providing a basis for imple-menting a need-to-know policy. Information asset classification is a process of catego-rizing information based on its level of sensitivity and importance, and applying appro-priate security controls based on the level of risk associated with that information1. A need-to-know policy is a principle that states that access to information should be granted only to those individuals who require it to perform their official duties or tasks2. The purpose of a need-to-know policy is to limit the exposure of sensitive information to unauthorized or unnecessary parties, and to reduce the risk of data breaches, leaks, or misuse. Information asset classification provides a basis for implementing a need-to-know policy by:

*Defining the value and protection requirements of different types of information

*Labeling the information with the appropriate classification level, such as public, internal, confidential, secret, or top secret

*Establishing the roles and responsibilities of information owners, custodians, and users

*Enforcing access controls and encryption for the information

*Documenting the security policies and procedures for the information

By providing a basis for implementing a need-to-know policy, information asset classi-fication can help organizations to protect their sensitive information, comply with rele-vant laws and regulations, and achieve their business objectives. The other options are not the greatest benefits of information asset classification. Helping to determine the recovery point objective (RPO) is not a benefit, but rather a consequence of applying security controls based on the classification level. RPO is the acceptable amount of data loss in case of a disruption3. Supporting segregation of duties is not a benefit, but rather a prerequisite for implementing a need-to-know policy. Segregation of duties is a principle that states that no single individual should have control over two or more phases of a business process or transaction that are susceptible to errors or fraud4. De-fining resource ownership is not a benefit, but rather a component of information asset classification. Resource ownership is the assignment of accountability and authority for an information asset to an individual or a group5.

Answer : D

The best way to support effective communication during information security incidents is to have predetermined service level agreements (SLAs) because they define the expectations and responsibilities of the parties involved in the incident response process, and specify the communication channels, methods, and frequency for reporting and updating on the incident status and resolution. Frequent incident response training sessions are not very effective because they do not address the communication needs or challenges during an actual incident. Centralized control monitoring capabilities are not very effective because they do not address the communication needs or challenges during an actual incident. Responsibilities defined within role descriptions are not very effective because they do not address the communication needs or challenges during an actual incident.

Answer : A

Initiating incident response is the first course of action for an information security manager when an employee reports the loss of a personal mobile device containing corporate information. This will help to contain the incident, assess the impact, and take appropriate measures to prevent or mitigate further damage. According to ISACA, incident management is one of the key processes for information security governance. Initiating a device reset, disabling remote access, and conducting a risk assessment are possible subsequent actions, but they should be part of the incident response plan.

Answer : B

Escalate to senior management, because this could help the information security manager to inform the decision-makers of the situation, explain the implications and trade-offs, and seek their guidance and approval for the next steps2. However, this answer is not certain, and you might need to consider other factors as well.

Answer : D

The greatest risk comes from not performing risk classification on the findings. Without classification, the organization cannot prioritize remediation efforts, allocate resources effectively, or understand the business impact of the vulnerabilities.

'Risk classification helps determine the priority for mitigating vulnerabilities and enables risk-informed decisions.''

--- CISM Review Manual 15th Edition, Chapter 2: Risk Assessment and Analysis*

Even if some findings are unfixed or reclassified, the lack of any classification process undermines the whole risk management effort.

Answer : D

An intrusion detection system (IDS) is a software or hardware device that monitors network traffic and detects unauthorized or malicious activities, such as attacks, intrusions, or breaches. An IDS can provide valuable evidence for an information security team to investigate an alleged breach of an organization's network, as it can capture and analyze the network traffic in real time or after the fact. An IDS can help to identify the source, type, scope, and impact of the breach, as well as to generate alerts and reports for further investigation.

File integrity monitoring software (FIM), security information and event management (SIEM) tool, and antivirus software are not single sources of evidence for an information security team to review. FIM software monitors files and directories on a network or system and detects changes or modifications that may indicate unauthorized access or tampering. SIEM tool collects and correlates data from various sources, such as logs, events, alerts, incidents, and threats, and provides a unified view of the security posture of an organization. Antivirus software scans files and programs on a network or system and detects malware infections that may compromise the security or functionality of the system.

However, these tools are not sufficient by themselves to provide conclusive evidence for an information security team to investigate an alleged breach of an organization's network. They may provide some clues or indicators of compromise (IOCs), but they may also generate false positives or negatives due to various factors, such as configuration errors, user behavior, benign activities, or evasion techniques. Therefore, an information security team should use multiple sources of evidence from different tools and methods to verify the validity and reliability of the findings.
