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.

During the containment phase, the immediate response to an incident involves limiting its scope and magnitude, which includes preserving evidence. This is crucial for a subsequent forensic analysis and for learning lessons from the incident to prevent future occurrences.

 Heuristic-based anti-malware is designed to detect new, previously unknown viruses and exploits by looking for known suspicious behavior patterns or anomalies. Unlike signature-based anti-malware, which relies on a database of known malware signatures, heuristic analysis can identify new threats without prior knowledge of the specific malware, making it more effective against unknown malware.

References: The effectiveness of heuristic-based anti-malware is supported by cybersecurity resources that highlight its ability to catch and block new and emerging threats before they can cause harm, as well as its capability to reduce false positives by evaluating the behavior of a file or program1. Additionally, heuristic analysis is recognized for its proactive threat detection, offering protection against malware that has yet to be discovered2.
