What should each Responsible Entity do regarding Transient Cyber Assets?

Each Responsible Entity must limit the usage of Transient Cyber Assets to essential business functions to ensure the security and integrity of the Critical Infrastructure. Transient Cyber Assets are typically devices that are not permanently connected to the system, and improper management can lead to increased vulnerability.

By limiting their use to only those functions that are absolutely necessary for business operations, organizations can reduce the risk of potential cyber threats. This means that any introduction of transient devices or access must be carefully controlled to prevent unauthorized access or malicious activity. Focusing on essential functions encourages a principle of least privilege, meaning individuals have only the access necessary to perform their jobs, which in turn minimizes exposure to possible threats.

In the context of cybersecurity practices, this approach aligns with established best security standards, which emphasize risk management and are supported by NERC CIP guidelines. Properly managing the introduction and use of transient assets helps ensure compliance with regulatory requirements and safeguards the reliability of the overall system.
