What is required under CIP-005 R1.2 for External Routable Connectivity?

Under CIP-005 R1.2, the requirement focuses on managing and controlling External Routable Connectivity for systems within the scope of the standard. This standard specifically emphasizes that external connectivity should be channeled through identified Electronic Access Points.

By routing external traffic through identified Electronic Access Points, organizations can establish controlled access points that allow for monitoring, logging, and enforcement of security policies. It helps in reducing the attack surface by ensuring that all external communications pass through vetted and monitored locations, which plays a crucial role in maintaining the security posture of the critical infrastructure.

This requirement is part of a broader strategy to manage risk associated with external network connections and to ensure that any incoming or outgoing communication is subject to appropriate scrutiny and controls, thereby mitigating potential vulnerabilities.

The other options, while relevant in various contexts of cybersecurity or specific security policies, do not pertain to the specific requirements outlined in CIP-005 R1.2 regarding external connectivity management.
