Selected Answer: C
it is most definitely option C. gemini.google.com explains it well below: "C. Potential back doors to the firewall software Here's why this is the most critical weakness: Direct Compromise: Backdoors provide attackers with unauthorized access to the firewall itself. This allows them to bypass the firewall's security controls entirely, rendering it ineffective. - Control of the Guardian: With control over the firewall, attackers can: - Modify rules to allow unauthorized access. - Monitor network traffic for sensitive information. - Launch attacks from within the network, appearing as legitimate internal traffic. Backdoors within firewall software pose the most significant threat as they directly compromise the integrity and security of the entire perimeter defense mechanism."
