Virtualization in the CIP Environment: Preparing for Compliance After FERC Order No. 919

The increasing use of virtualization across operational technology environments has transformed how organizations deploy and manage critical infrastructure. Until recently, however, the CIP Reliability Standards largely reflected a physical, device-based approach centered on traditional security perimeter, and did not not fully account for virtualized architectures.

Key Takeaways

• FERC Order No. 919 modernizes the CIP Reliability Standards framework by recognizing virtualized technologies and enabling greater flexibility in how entities design and secure CIP environments.
• While virtualization offers significant operational, security, and cost benefits, it also introduces new compliance considerations involving asset identification, access controls, configuration management, and supply chain oversight.
• Utilities and other registered entities planning to use virtualization in their CIP environments should begin preparing now by evaluating governance frameworks, vendor relationships, and implementation strategies before the new standards become enforceable.

FERC Order No. 919 marks a significant step toward modernizing that framework. By approving revisions to multiple CIP Reliability Standards and related glossary definitions, the order provides registered entities with greater flexibility to implement virtualized technologies while maintaining compliance obligations designed to protect the Bulk Electric System. Although the revised standards will not become enforceable for several years, organizations interested in deploying virtualized technologies in their CIP environments should begin evaluating the opportunities and implementation challenges now, in part because the documentation used to implement and prove CIP compliance with virtual technologies will differ significantly from current practice.

Modernizing the CIP Framework for Virtualization

Virtualization allows multiple operating systems and applications to operate independently on shared physical hardware, reducing reliance on dedicated devices while improving scalability, resilience, and operational flexibility. Although these technologies have become commonplace across enterprise IT environments, earlier CIP standards were built around identifiable physical Cyber Assets, creating practical challenges for organizations seeking to virtualize operational technology environments.

Rather than creating a standalone virtualization standard, the approved changes embed virtualization concepts across the existing CIP framework. The changes introduce new terminology and concepts designed to recognize virtualized infrastructure while preserving the underlying cybersecurity objectives of the CIP standards.

Among the most significant developments are new definitions for Virtual Cyber Assets and Shared Cyber Infrastructure, together with revisions to concepts such as Electronic Security Perimeters and Electronic Access Points. These changes shift the framework from one focused primarily on physical devices to one that better accommodates logical architectures and shared computing environments.

The revised standards also recognize that virtualized environments operate differently than traditional physical infrastructure. Virtual machines may be created, migrated, cloned, rebuilt, or removed dynamically, requiring compliance programs that focus less on individual hardware components (i.e. no longer having a single physical asset that provides a single OT/IT function) and more on overall system architecture and security outcomes.

New Compliance Considerations for Virtualized Environments

Although the revised standards provide greater flexibility, they also introduce new compliance responsibilities that extend across multiple areas of the CIP program.

Among the most significant considerations are:

• Asset identification: Registered entities will need to identify, classify, and track Virtual Cyber Assets and Shared Cyber Infrastructure alongside traditional Cyber Assets.
• Security management: Access controls, configuration management, patching, monitoring, and incident response programs must account for virtualized environments and management interfaces.
• Supply chain oversight: Vendor-supported virtualization platforms and cloud-based services may expand supply chain risk management obligations.

Several standards are particularly affected by these changes, with the most operationally significant changes arising under CIP-007 and CIP-010. For example:

• CIP-004: Personnel risk assessments, training, and access management requirements now extend to individuals responsible for administering Shared Cyber Infrastructure or other components of virtualized environments.
• CIP-005: Electronic Security Perimeter concepts have been updated to recognize logical boundaries and policy enforcement points, reflecting modern network architectures.
• CIP-007: System security management concepts expanded to include the virtualization layer.
• CIP-010: Configuration management requirements also evolve beyond static physical device baselines to accommodate dynamic virtual environments.
• CIP-013: Supply chain risk management requirements now more clearly account for vendor-supported Shared Cyber Infrastructure and virtualization platforms.

These changes recognize that virtualized infrastructure can improve security when implemented effectively. Technologies such as microsegmentation, policy-based access controls, and zero trust architectures may enhance protection of Bulk Electric System assets while improving operational flexibility.

At the same time, virtualization introduces new risks that organizations will need to manage carefully. Shared infrastructure can increase the consequences of configuration errors, while virtual environments may complicate asset inventories, security monitoring, and forensic investigations. Hypervisors, management platforms, and shared computing resources also become critical components (and potential vulnerabilities) requiring appropriate protection.

The revised standards also replace certain existing "technically feasible" provisions with a new “per-system capability” mechanism. While this provides additional where a system cannot perform a required action due to system limitations, entities relying on the mechanism will need to maintain sufficient documentation demonstrating the limitation and what alternative mitigation measures have been implemented—including the efficacy of the security achieved through those alternative measures.

Vendor Governance and Implementation Planning

The transition toward virtualized environments also places greater emphasis on vendor governance and contractual risk management.

Many virtualization platforms rely on third-party providers for infrastructure, software, cloud services, remote support, or managed operations. As organizations expand their use of these technologies, contractual arrangements become an increasingly important component of CIP compliance.

Organizations should consider whether vendor agreements adequately address:

• Compliance support and audit documentation;
• Access management and personnel controls;
• Incident response coordination;
• Supply chain security obligations;
• Data protection and information handling; and
• Appropriate allocation of liability for both regulatory compliance and consequential operational incidents.

These issues are particularly important because the use of virtualized technologies may introduce new operational and security risks, including risks tied to vendor access, shared infrastructure, system visibility, and incident response dependencies. Registered entities must balance those risks through careful contract management, while recognizing that they remain responsible for demonstrating compliance even where operational functions are performed by third parties. Registered entities should therefore ensure their vendor engagements provide sufficient visibility into cybersecurity controls, operational redundancies, and supporting documentation to facilitate regulatory audits and ongoing compliance activities.  For example, information and supporting documentation may be needed from vendors on an expedited basis (such as overnight) during on-site audits and vendor SMEs may be needed to explain how vendor-side controls are managed.  Because a failure to demonstrate compliance will often result in a finding of non-compliance, entities subject to the CIP standards relying on vendors for any aspects of compliance should ensure the necessary regulatory cooperative provisions are included in their service agreements. 

Implementation planning should also extend to regulator engagement, particularly where organizations are considering novel approaches that will affect existing compliance programs. Early planning may also help identify documentation, governance, and operational controls needed to demonstrate compliance once virtualized systems become operational.

Independent cybersecurity assessments and recognized security certifications may also provide useful evidence supporting broader governance and risk management efforts, although they do not replace compliance with the CIP Reliability Standards themselves.

Looking Ahead

FERC Order No. 919 reflects the continued evolution of the CIP Reliability Standards alongside advances in operational technology. By recognizing virtualization within the existing compliance framework, the revised standards provide registered entities with greater flexibility to adopt technologies that may improve operational resilience, efficiency, and cybersecurity.

The transition, however, will require more than simply deploying new technology. Organizations should evaluate how virtualization affects asset inventories, governance structures, vendor relationships, documentation practices, and compliance programs well before the revised standards become enforceable.

For utilities and other registered entities, virtualization presents an opportunity to modernize critical infrastructure while strengthening cybersecurity. Organizations that begin planning early and integrate technical, operational, and compliance considerations into implementation strategies will be better positioned to realize those benefits while maintaining alignment with the evolving CIP framework.
