The Operational Technology Cybersecurity Coalition (OTCC) has formally petitioned the Cybersecurity and Infrastructure Security Agency (CISA) to establish mandatory, binding security requirements for operational technology (OT) across the Federal Civilian Executive Branch. This call to action, articulated in a report released on October 6, highlights a growing consensus among security experts that the current lack of standardized oversight for federal OT assets leaves the nation’s critical infrastructure vulnerable to significant physical and digital threats.
The coalition argues that while information technology (IT) security has seen rigorous federal standardization, the OT landscape—which controls everything from building climate systems to life-critical power grids—remains dangerously fragmented. According to the OTCC, there is currently no comprehensive directive that establishes minimum security practices for federal OT, resulting in a systemic lack of visibility for CISA regarding the true scope of risk across civilian agencies. By proposing a Binding Operational Directive (BOD), the coalition aims to bridge this gap, ensuring that OT security is treated with the same level of urgency as traditional IT systems.
The Scope of the Problem
The urgency of this proposal is underscored by the sheer scale of the federal footprint. The OTCC points out that federal agencies rely on complex OT systems within more than 8,000 facilities managed by the General Services Administration (GSA). These environments are not merely office spaces; they include high-stakes facilities such as government laboratories, hospitals, and ports of entry. In these locations, OT systems operate the fundamental building blocks of modern life: HVAC systems, electrical grids, physical access control mechanisms, water distribution, and comprehensive building automation.
A breach in these systems does not merely risk the loss of data; it risks the loss of control over physical environments. An attacker gaining access to a facility’s building automation system could potentially disrupt power, bypass security protocols, or compromise the safety of personnel within a government laboratory or hospital. Despite these high stakes, the oversight mechanisms currently in place have proven insufficient to keep pace with the evolving threat landscape.
This lack of control was further highlighted by a sobering report published by the Government Accountability Office (GAO) on September 30. The GAO’s investigation into 22 civilian agencies revealed that only seven had fully complied with Office of Management and Budget (OMB) requirements to maintain a complete inventory of their networked OT and Internet of Things (IoT) devices. These inventories were mandated to be completed by September 2024, yet the majority of agencies fell short of the deadline. Compounding the concern, the GAO noted that the OMB had not yet issued updated guidance for fiscal year 2026, creating a vacuum of accountability and direction that leaves agencies struggling to prioritize their security investments.
Defining the Path Forward: A Proposed Directive
The OTCC’s proposal for a binding directive is designed to move beyond the current ad-hoc approach to security. The coalition suggests that the directive should compel agencies to designate a specific senior official or dedicated office responsible for OT security, effectively elevating the issue to the enterprise risk management level. By integrating OT risk into the broader organizational risk strategy, agencies would be forced to acknowledge that security is not just an IT problem, but a core operational requirement.
The proposed baseline for the directive includes several foundational pillars: comprehensive asset inventory, strict network segmentation, secure remote access controls, robust configuration management, thorough incident preparedness, and verified recovery procedures. These controls are intended to serve as a minimum threshold for federal agencies, ensuring that at the very least, they have a clear understanding of what they are protecting and how they would respond to a compromise.
However, the proposal has sparked a nuanced debate regarding the limits of such a directive. John Gallagher, vice president at Viakoo, expressed support for the coalition’s initiative while noting that the current proposal remains incomplete. Gallagher argues that while an inventory is a necessary starting point, it is fundamentally insufficient without a clear plan for remediation.
"Missing from the OTCC’s goals is remediation," Gallagher warned. He emphasized that without automated patch and configuration management, agencies are likely to face a mounting backlog of vulnerabilities that will quickly overwhelm their operational teams. The reality for many agencies is that they lack the personnel to manually track and patch thousands of disparate OT devices. Without automation, the "baseline" security requirements could lead to a false sense of security while the actual vulnerabilities persist in the background.
The OTCC’s current priority list does include critical measures such as the rotation of default passwords, the implementation of multifactor authentication (MFA), network segmentation, and the maintenance of secure backups. These are essential, high-impact controls that can mitigate the most common attack vectors. Yet, the report notably omits calls for mandatory, widespread patching or firmware updates. Gallagher points out that this is a significant oversight, as attackers frequently exploit unmanaged default passwords and obsolete firmware to gain a foothold in sensitive environments.
Balancing Containment with Operational Continuity
The push for a binding directive comes as CISA continues to roll out its "CI Fortify" resilience initiative, which emphasizes the ability of organizations to continue operations through a compromise. The OTCC believes its proposed directive would complement this initiative by establishing a strong, pre-incident baseline. The goal is not just to prevent an initial breach, but to ensure that if an intrusion occurs, it cannot be leveraged to cause catastrophic physical consequences.
This focus on containment is particularly vital in the industrial sector, where the traditional IT approach of "patch early, patch often" is frequently impossible. Louis Eichenbaum, federal CTO at ColorTokens, highlights the practical reality that many industrial devices—such as legacy controllers or highly specialized medical equipment—cannot be patched immediately without causing significant operational disruption.
"Patching remains essential, but we cannot patch our way out of cyber risk," Eichenbaum stated. He argues that in environments where uptime is non-negotiable, segmentation becomes the most effective strategy to limit an attacker’s lateral movement. By compartmentalizing networks, an agency can ensure that even if an attacker gains access to one compromised controller, they are effectively contained and unable to pivot to more sensitive areas of the facility’s infrastructure.
Furthermore, the influence of a federal directive could extend far beyond the civilian government. While CISA’s binding directives are legally enforceable only for certain Federal Civilian Executive Branch agencies, they often serve as a de facto standard for the private sector. Private operators of critical infrastructure often look to federal guidelines as the "gold standard" for cybersecurity best practices.
Eichenbaum emphasized that a strong federal OT baseline would create a ripple effect throughout the economy. "It would give critical-infrastructure owners a practical model, provide vendors with clearer security expectations, and allow federal procurement to encourage secure-by-design products," he added. By leveraging the government’s immense purchasing power, a binding directive could influence the broader market, compelling vendors to prioritize security in their designs rather than treating it as an afterthought.
As CISA weighs the proposal, the conversation reflects a broader transition in the cybersecurity landscape. The shift toward recognizing OT as a primary attack surface marks a departure from the days when facility controls were considered "air-gapped" and immune to digital interference. Today, with the proliferation of smart devices and the integration of OT into enterprise networks, the distinction between IT and OT security is rapidly evaporating. The OTCC’s call for a binding directive serves as a formal acknowledgment of this new reality, signaling that the federal government must now move to codify the security of the systems that underpin the nation’s critical infrastructure. Whether the agency will adopt these recommendations in full, or refine them to include the robust remediation strategies urged by industry observers, remains a pivotal question for federal cyber policy in the coming year.
