Set up secure audit logging
About secure audit logging
When audit logging is enabled, all sign in 
activity and configuration changes on the 
video system are recorded.
Use the Security > Audit > Logging > 
Mode setting to enable audit logging. 
Audit logging is disabled by default. 
In ExternalSecure audit logging mode 
the video system sends encrypted audit 
logs to an external audit server (syslog 
server), which identity must be verified by 
a signed certificate.
The signature of the audit server is 
verified using the same CA list as other 
servers/clients.
If the audit server authentication fails, no 
audit logs are sent to the external server.
1.  Open the Security category.
2.  Find the Audit > Server 
settings, and enter the 
Address of the audit server. 
If you set PortAssignment to 
Manual, you must also enter 
a Port number for the audit 
server. 
Click Save for the changes 
to take effect.
3.  Set Audit > Logging > Mode 
to ExternalSecure. 
Click Save for the change to 
take effect.
Sign in to the web interface, navigate to Setup > Configuration. The certificate authority (CA) that verifies the certificate 
of the audit server must be in the video system’s list of 
trusted certificate authorities. Otherwise, logs will not be 
sent to the external server.
Refer to the ► Manage the list of trusted certificate 
authorities (CAs) chapter how to update the list.
