What should be included in Periodic Reviews of BES Cyber Assets?

In the context of Periodic Reviews of Bulk Electric System (BES) Cyber Assets, it is essential to conduct a review even if no BES Cyber Assets were previously identified. This practice is fundamental to ensure that the organization remains compliant with NERC Critical Infrastructure Protection (CIP) standards. Periodic reviews should examine the entire environment to identify any changes or new developments that may impact the security posture or lead to new assets being classified as BES Cyber Assets.

Conducting a review regardless of prior identifications ensures that organizations are proactive about cybersecurity risks and allows them to identify potential vulnerabilities or new assets that may not have been considered previously. This approach underscores the importance of continuous monitoring and reassessment, which are critical for maintaining a robust cybersecurity framework. Being vigilant about this process helps organizations stay ahead of potential threats and ensures compliance with regulatory requirements.

Other options, such as focusing solely on new technological advancements or customer feedback, do not encompass the comprehensive nature of an effective review process. Regular market analysis, while useful for many aspects of strategic planning, may not specifically address the immediate needs of assessing the cybersecurity of BES Cyber Assets. Therefore, reviewing even in the absence of previously identified assets is the most comprehensive and compliant approach.
