Which type of detection relies on a specific security policy to flag violations?

Policy-based detection is grounded in predefined security policies that outline acceptable behaviors and practices within a network or system. This type of detection examines events and issues alerts when any action deviates from these established rules, effectively flagging violations based on the criteria set by the organization’s security policies.

This approach is particularly useful as it allows organizations to tailor their security measures to their specific needs, industry standards, and regulatory requirements. By relying on a security policy, policy-based detection can provide clear guidance on what constitutes a violation, which makes it easier for security teams to respond quickly and appropriately to potential threats.

In contrast, other detection types have different methodologies; for example, signature-based detection focuses on known threats and malware signatures, anomaly-based detection searches for deviations from established baselines of normal behavior, and traffic-based detection analyzes data packets without necessarily corresponding to a specific policy. Each has its benefits and drawbacks, but policy-based detection directly relates to the adherence to organizational standards, making it distinct and relevant in maintaining compliance and security.
