Overview

The SBC Core supports multiple event log types. The two most applicable SBC security-related event log types are the Security and Audit logs.

  • Security logs include IP Policer alarms and failed login attempts.
  • Audit logs include login and logout information, plus any configuration changes executed.
Note

JITC requires the audit (.AUD) and security (.SEC) logs to be cryptographically protected. Since both logs are required to be hashed, this functionality is extended to support the hashing of all Event Logs on the SBC.

Note

The audit log generates all output at the Info level and is unalterable.


The Filter Level for the audit event type is always set to Info-level logging and cannot be altered. Ribbon recommends setting the Filter Level for the security event type to Info-level logging for maximum security visibility.
