CIP-003 R2 applies to which entities specifically?

CIP-003 R2 specifically applies to entities that possess low impact Bulk Electric System (BES) Cyber Systems. This requirement is part of the NERC Critical Infrastructure Protection standards, which aim to secure critical infrastructure from various cyber threats. Under CIP-003 R2, these entities are mandated to implement security management controls to protect their cyber systems and reduce vulnerabilities.

Understanding the focus on low impact BES Cyber Systems is essential, as these systems, while classified as low impact, still require protective measures to ensure the overall reliability and security of the bulk electric system. This highlights the regulatory emphasis on comprehensive cybersecurity measures across all levels of impact, including those deemed low.

The other options do not correctly represent the scope of CIP-003 R2. Regulated entities with high impact systems, transmission system operators, and backup power generation facilities are associated with different CIP requirements that correspond to their specific roles or the impacts of their systems, but they do not fall under the purview of CIP-003 R2. Thus, the focus on low impact BES Cyber Systems makes the correct choice clear.
