Security Audit Logging Mode
Determine where to record or transmit the audit logs. When using the External or
ExternalSecure modes, you also must enter the address and port number for the audit server in
the Security Audit Server Address and Security Audit Server Port settings.
NOTE: Restart the system for any change to this setting to take effect.
Requires user role: AUDIT
Value space: <Off/Internal/External/ExternalSecure>
Off: No audit logging is performed.
Internal: The system records the audit logs to internal logs, and rotates logs when they are
full.
External: The system sends the audit logs to an external audit server (syslog server). The
audit server must support TCP.
ExternalSecure: The system sends encrypted audit logs to an external audit server (syslog
server) that is verified by a certificate in the Audit CA list. The Audit CA list file must be
uploaded to the codec using the web interface. The common_name parameter of a
certificate in the CA list must match the IP address of the audit server.
Security Audit Logging Mode: Off
Example:
Security Audit Server Address
Enter the IP address of the audit server. Only valid IPv4 or IPv6 address formats are accepted.

Security Audit Server Port
Enter the port of the audit server that the system shall send its audit logs to. The default port
is 514. This setting is only relevant when Security Audit Logging Mode is set to External or
ExternalSecure.

Security Audit OnError Action
Determine what happens when the connection to the audit server is lost. This setting is only
relevant when Security Audit Logging Mode is set to ExternalSecure.
NOTE: Restart the system for any change to this setting to take effect.
Requires user role: AUDIT
Value space: <Halt/Ignore>
Halt: If a halt condition is detected the system is rebooted and only the auditor is allowed
to operate the unit until the halt condition has passed. When the halt condition has passed
the audit logs are re-spooled to the audit server. Halt conditions are: A network breach
(no physical link), no audit server running (or wrong audit server address or port), TLS
authentication failed (if in use), local backup (re-spooling) log full.
Ignore: The system will continue its normal operation, and rotate internal logs when full.
When the connection is restored it will again send its audit logs to the audit server.
Security Audit OnError Action: Ignore
