What is a fundamental principle behind updating firewall rules with threat intelligence?

• A. To maintain legacy support for older systems.
• B. To limit user access to certain features.
• C. To strengthen defenses against new threats.
• D. To reduce operational complexity.

Answer: (C)

Updating firewall rules with threat intelligence is fundamentally designed to strengthen defenses against new threats. Threat intelligence refers to the knowledge about existing or emerging threats that can help in identifying and mitigating vulnerabilities. By incorporating this intelligence into firewall rules, organizations can proactively adapt their defenses to counteract the tactics and techniques employed by cyber adversaries. This principle is rooted in the need to remain vigilant against evolving threats, which can include malware, phishing attempts, and other types of attacks that may exploit weaknesses in a network's defenses. Essentially, as threat actors change their strategies, updating firewall rules allows for an adaptable security posture that is responsive to the latest threat landscape. The other options do not align with the primary goal of integrating threat intelligence into firewall management. Maintaining legacy support, limiting user access, or reducing operational complexity do not directly enhance the firewall's ability to protect against new and dynamic threats. Instead, they may serve different operational or administrative objectives but are not fundamental to the purpose of using threat intelligence for updating firewall rules.
