According to CIP-007 R3, what is the primary purpose of the requirement?

The primary purpose of CIP-007 R3 is centered on Malicious Code Prevention. This requirement emphasizes the importance of implementing mechanisms to protect against malware and other forms of malicious code that could compromise the security and integrity of operational technology systems within the electric sector.

CIP-007 R3 stipulates that entities must have procedures in place to detect and prevent the introduction of malicious code into systems that could impact critical infrastructure. This involves measures like regular updates to antivirus programs, use of scanning tools, and ensuring systems are protected against vulnerabilities that can be exploited by malicious actors.

The focus on Malicious Code Prevention is crucial in safeguarding the reliability of the electric grid and preventing potential disruptions that could arise from cyber threats. Through this requirement, NERC establishes a framework for utilities to proactively address cybersecurity risks associated with malicious software, ensuring that essential systems remain secure and functional.
