Which type of detection relies on a specific declaration of security policy?

The type of detection that relies on a specific declaration of a security policy is policy-based detection. This method involves defining a clear set of rules and standards that outline what is acceptable within a network or system. The detection system then monitors activities and compares them against these established policies to identify any violations or deviations.

In the context of security, policy-based detection is essential because it combines the organization's unique security requirements with automated monitoring. If an action, user behavior, or system event does not align with the defined policy, it can trigger an alert or response, indicating a potential security issue.

This detection approach effectively enforces compliance and governance by ensuring that all activities adhere to the pre-established guidelines. It provides a framework for consistent monitoring and incident response, making it a valuable tool in maintaining security within an organization.

Other detection methods, such as signature-based or anomaly-based detection, do not rely directly on predefined policies. Signature-based detection focuses on known patterns of malicious activity, while anomaly-based detection looks for deviations from normal behavior rather than adhering strictly to a policy. Behavior-based detection is also more focused on identifying unusual patterns rather than working from a set policy.
