To reduce the risk of future security breaches related to outdated firewall configurations
D. SSH key rotation: Regularly rotating SSH keys is a good practice for maintaining secure access to systems, including firewalls. However, the primary concern here seems to be the lack of updates to the firewall rules and configurations. Therefore, more broadly, this issue highlights the need for regular reviews and updates of firewall rules and configurations to ensure they are aligned with current security best practices and threats.
A. Video surveillance: While important for physical security, it does not directly address the issue of outdated firewall configurations.
B. Biometric controls: This also pertains to physical security and access control rather than network security or firewall management.
C. Password encryption: While critical for protecting credentials, it does not directly affect firewall configuration management or updates.
