What is the requirement for interactive remote access sessions according to CIP-005?

The requirement for interactive remote access sessions according to CIP-005 is to utilize encryption that ensures the security of data in transit. This encryption is essential for protecting the integrity and confidentiality of sensitive information as it travels over potentially untrusted networks. While it is important to have a robust security plan in place that may include multifactor authentication and physical access controls, CIP-005 specifically emphasizes the necessity of encryption for remote sessions to mitigate risks associated with unauthorized access or interception.

In this context, while multi-factor authentication enhances security significantly, it does not directly address the encryption of the communication channel used during remote access. A documented visitor control program and maintenance of physical access control systems relate more to physical security measures, which are important but outside the direct scope of remote access requirements as defined in this standard. The focus of CIP-005 on encryption during interactive remote access sessions underscores the importance of safeguarding critical systems from cyber threats.
