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 to the security log file without affecting the current
log output rules.
Saving security logs to the security log file
After you enable the saving of the security logs to the security log file:
• The system first outputs security logs to the security log file buffer.
• The system saves the logs from the security log file buffer to the security log file at a specified
interval (a user authorized the security-audit role can can also manually save security logs to
the security log file).
• After the security logs are saved, the buffer is cleared immediately.
The device supports only one security log file. To avoid security log loss, you can set an alarm
threshold for the security log file usage. When the alarm threshold is reached, the system outputs a
message to inform the administrator. The administrator can log in to the device with the
security-audit user role and back up the security log file to prevent the loss of important data.
