Control / Question

Establish OT/ICS specific cybersecurity policies (operational). Enterprise or IT policies are common, but they often do not address the safety, availability, regulatory, technical, and incident-response requirements of OT systems.

C2M2 PROGRAM-1a (MIL1) NIST CSF 2.0 GV.PO NIST SP 800-53 PM-1 NIST SP 800-82r3 §3.3.1
DOE C2M2 v2.1

PROGRAM-1a — Cybersecurity Program Strategy

Section 6.10, Cybersecurity Program Management (PROGRAM), Objective 1

Relevant requirement: The organization has a cybersecurity program strategy, which may be developed and managed in an ad hoc manner.

Supports the baseline expectation that cybersecurity is governed as a formal program, not a set of disconnected IT activities.

GV.PO — Policy

Appendix A, CSF Core, GOVERN Function

Relevant requirement: Organizational cybersecurity policy is established, communicated, and enforced; policy is reviewed and updated as requirements, threats, technology, and mission change.

Use this to test whether policy is operational, communicated, enforced, and periodically maintained for the OT/ICS context.

PM-1 — Information Security Program Plan

Program Management control family

Relevant requirement: Develop, disseminate, review, update, and protect an organization-wide information security program plan that identifies roles, responsibilities, management commitment, coordination, and compliance.

Use this as the formal control-plan basis for management commitment, policy coverage, and assigned responsibilities.

§3.3.1 — Establish OT Cybersecurity Governance

Section 3.3, Development and Deployment of an OT Cybersecurity Program

Relevant requirement: OT governance should include policies, procedures, and processes for managing regulatory, legal, risk, environmental, and operational requirements, with assigned responsibilities and accountability.

This is the OT-specific anchor: it explicitly addresses OT governance, regulatory/legal obligations, operational requirements, roles, and accountability.
