This paper addresses the shortcomings of existing patching requirements in the electric sector, emphasizing the frequent violations of CIP-007-6 R2 – which specifically addresses security patching – and the growing operational burden on organizations. Vulnerability remediation should be an ongoing process instead of a one-time solution, as threats continuously evolve and previously patched vulnerabilities can reappear. By transitioning to a risk-informed remediation approach, leveraging Stakeholder-Specific Vulnerability Categorization (SSVC) and the Cybersecurity Advisory Framework (CSAF) to enhance decision-making and operational security, organizations can prioritize vulnerabilities based on actual risk impact rather than relying on reactive, compliance-driven patching.

In the field of vulnerability management, remediation, workaround, and mitigation are three common terms used to describe methods of addressing a vulnerability. They are sometimes used interchangeably, but their meanings can vary slightly across different vendors and organizations. To help with understanding the subtle differences between these terms—and how they are used—here’s a breakdown of how our team defines each. 

As industries become more connected, OT cybersecurity is increasingly crucial. OT systems, which control physical processes like energy production and water treatment, are vulnerable to cyber threats due to outdated infrastructure and newer connectivity. The integration of OT with IT networks has heightened the risk, as seen in breaches like U.S. telecommunications and American Water, which caused operational disruptions and safety concerns. Securing OT systems is vital for protecting both data and the critical infrastructure that supports daily life.
