Log Maintenance

Inspect and maintain your log files on a regular schedule. Use these methods to secure log files:

• Enable logging and send system logs to a dedicated secure log host.

• Configure logging to include accurate time information, using Network Time Protocol (NTP) and timestamps.

• Perform regularly scheduled scans of network device logs for unusual network activity or access.

• Review logs for possible incidents and archive them in accordance with a security policy.

• Periodically retire log files when they exceed a reasonable size. Maintain copies of the retired files for possible future reference or statistical analysis.
