Which component must be utilized for Interactive Remote Access Management according to CIP-005 R2?

The correct choice emphasizes the necessity of having documented processes for any interactive remote access management as required by CIP-005 R2. This standard mandates that organizations must develop, implement, and maintain processes that ensure secure remote access to their Critical Cyber Assets.

Interactive Remote Access refers to methods that allow users to establish a connection to the system where they can manage devices and data from a distance. The importance of having documented processes is to ensure that access controls are clear and consistent, abiding by NERC guidelines, thus minimizing the risk of unauthorized access. These documented processes will include procedures for granting, monitoring, and revoking access rights, which are essential for maintaining the integrity and security of critical infrastructure.

The other options do not address the core requirement of the standard. Public network access could pose security risks without proper management, while physical security measures, while important, are not the focus of this requirement. Authorization from third-party vendors does involve elements of governance but does not encapsulate the need for structured procedures in the context of remote access management.
