Cybersecurity Audit Changed Cybersecurity-Audit-Certificate Questions

The main objective of an intrusion detection system (IDS) policy is to establish the criteria for what constitutes an intrusion event and the reporting requirements once such an event is detected. This includes defining what activities are considered anomalies, ensuring that security breaches are identified, and specifying how and to whom these incidents should be reported. The policy sets the foundation for how intrusions are detected, assessed, and managed within an organization’s network infrastructure1.

References: ISACA’s resources on cybersecurity highlight the importance of having a clear IDS policy that outlines the detection and response procedures for security incidents. Such a policy is crucial for the effective monitoring and management of potential security breaches, ensuring that they are promptly identified and addressed1.

An example of an attack attribute of an advanced persistent threat (APT) that is designed to remove data from systems and networks is an exfiltration attack vector. An exfiltration attack vector is a method or channel that an APT uses to transfer data from a compromised system or network to an external location. Examples of exfiltration attack vectors include email, FTP, DNS, HTTP, or covert channels.

The role of risk management is to provide an oversight function, ensuring that the business management’s decisions align with the organization’s risk appetite and strategy. If the risk management function were to overrule business management decisions, it could compromise its objectivity. This could lead to a conflict of interest and diminish the function’s ability to provide unbiased oversight and measurement of business activities.

References: The ISACA resources suggest that risk management should be a separate function that aids in the objective assessment and management of risks without directly intervening in business decisions12. This separation is crucial to maintain the integrity of the risk management process and to ensure that it can effectively monitor and measure business activities from an independent standpoint.
