The North American Electric Reliability Corporation (NERC) addresses patching in NERC CIP 007-6 Requirement 2. Summarily, it requires Bulk Power System (BPS) Operators/Owners to identify the source or sources utilized to provide
Entiter Security related patches for Cyber Assets utilized in the operation of the Registered Entities are required to check for new patches once every thirty five calendar days. Upon identification of a new patch, entities are required to evaluate applicability of a patch and then complete mitigation or installation activities within 35 calendar days of completion of assessment of applicability.e BPS.
An initial attempt to create information security standards for the electrical power industry was created by NERC in 2003 and was known as NERC CSS (Cyber Security Standards). Subsequent to the CSS guidelines, NERC evolved and enhanced those requirements. The most widely recognized modern NERC security standard is NERC 1300, which is a modification/update of NERC 1200. The newest version of NERC 1300 is called CIP-002-3 through CIP-009-3 (CIP=Critical Infrastructure Protection). These standards are used to secure bulk electric systems although NERC has created standards within other areas. The bulk electric system standards also provide network security administration while still supporting best-practice industry processes.
