V16.3 Security Events

This section defines requirements for logging security-relevant events within the application. Capturing these events is critical for detecting suspicious behavior, supporting investigations, and fulfilling compliance obligations.

This section outlines the types of events that should be logged but does not attempt to provide exhaustive detail. Each application has unique risk factors and operational context.

Note that while ASVS includes logging of security events in scope, alerting and correlation (e.g., SIEM rules or monitoring infrastructure) are considered out of scope and are handled by operational and monitoring systems.
