How should Responsible Entities manage Transient Cyber Assets?

Managing Transient Cyber Assets involves the need for a flexible yet robust approach to ensure that these assets are adequately assessed and controlled to protect the grid's reliability and security. The correct choice emphasizes the importance of both continuous oversight and the ability to respond to immediate requirements.

Transient Cyber Assets, which can include devices that are connected temporarily to the system, need to be managed dynamically. Continuous management ensures ongoing monitoring for vulnerabilities and risks, which is critical for identifying potential security threats that may arise while these assets are in use. On-demand management is also necessary because it allows Responsible Entities to take immediate action based on current needs, such as responding to unexpected risks or reviewing the security posture of assets as they come online or offline.

By utilizing both Continuous and on-demand strategies, Responsible Entities can effectively address the unique challenges associated with transient assets, thereby enhancing the overall cybersecurity posture without compromising operational flexibility. This dual approach aligns with the intent of the NERC CIP standards, which emphasize the need for comprehensive risk management practices that adapt to evolving threats while maintaining the reliability of critical infrastructure.
