What is the objective of the Electronic Security Perimeter as outlined in CIP-005?

The objective of the Electronic Security Perimeter, as outlined in CIP-005, is to limit access to only authorized individuals and systems. This standard focuses on establishing a secure boundary around critical cyber assets by implementing measures that prevent unauthorized access. The Electronic Security Perimeter serves to protect sensitive information and systems from potential threats, ensuring that only those who are verified and have legitimate reasons can interact with or access these assets.

By doing so, it significantly enhances the security framework of the organization and helps mitigate risks stemming from both internal and external sources. The emphasis on restricting access underscores the vital importance of safeguarding critical infrastructure, aligning with the overall goals of the NERC CIP standards aimed at maintaining the reliability and security of the bulk electric system.
