Managing security logs
Security logs are very important for locating and troubleshooting network problems. Generally, security
logs are output together with other logs. It is difficult to identify security logs among all logs.
To solve this problem, you can save security logs into a security log file without affecting the current log
output rules.
The configuration of this feature and the management of the security log file are separate, and the
security log file is managed by a privileged user. After logging in to the device, the administrator can
enable the saving of security logs into the security log file and configure related parameters However,
only the privileged user, known as the security log administrator, can perform operations on the security
log file. The privileged user must pass AAA local authentication and log in to the device. No other users
(including the system administrator) can perform operations on the security log file.
