1. Review Firewall Rules:
This involves reviewing the rules and configurations of the firewall system to ensure they are up-to-date and consistent with industry best practices.
2. Check System Logs:
Examining system logs helps detect any unauthorized access attempts or malicious activities that could have been prevented by proper configuration.
3. Analyze Network Activity:
Monitoring network traffic can identify any suspicious activity, such as data exfiltration, which would be a sign of compromised security.
4. Validate External Connections:
Verifying all external connections ensures that only authorized parties can gain access to the system and its data.
5. Update Software Patches and Firmware:
Installing the latest system updates helps ensure that the firewall is running the most secure version of its software.
6. Monitor Account Usage:
Regularly monitoring user accounts for any suspicious activity can help detect and prevent unauthorized access attempts.
7. Scan for Vulnerabilities:
By scanning for security vulnerabilities, companies can better understand how their firewalls might be exploited by malicious actors in the future.
8. Test Firewall Rules:
It's important to regularly test firewall rules to confirm they are configured correctly and provide the desired levels of protection against threats.
