Pro Tips for Effective Firewall Monitoring
- Schedule Inspections During Low Traffic Periods: Whenever possible, conduct detailed inspections during periods of low network traffic to minimize the impact on business operations while still gathering accurate performance metrics.
- Document Configuration Changes: Maintain a detailed change log for all firewall configuration modifications, including who made the change, what was changed, when it was implemented, and why it was necessary.
- Implement the Principle of Least Privilege: Ensure that monitoring terminals and administrative access follow the principle of least privilege, with users having only the permissions necessary to perform their specific job functions.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of your firewall monitoring terminal. Adapt these steps to your specific firewall platform and security requirements.
Performance Assessment Procedure
- Login to monitoring interface with appropriate credentials
- Run system diagnostics to check CPU, memory, and disk utilization
- Review performance metrics over the past 24 hours, 7 days, and 30 days
- Identify any recurring patterns of resource exhaustion or bottlenecks
- Document baseline performance for future comparison
Rule Audit Procedure
- Export current ruleset to a secure location for analysis
- Check for deprecated, redundant, or contradictory rules
- Verify that each rule has appropriate documentation
- Confirm rule order optimization for performance
- Validate that business-critical applications have appropriate rules
Access Control Verification
- Review list of users with administrative access
- Validate that all admin users have appropriate authorization
- Test multi-factor authentication functionality
- Confirm password policy enforcement
- Verify separation of duties for critical changes
Log Analysis Procedure
- Verify logs contain all required fields (timestamp, source, action, etc.)
- Confirm logs are being successfully forwarded to SIEM
- Check log storage capacity and retention settings
- Validate that log search functionality is operational
- Test alert generation from significant log events
