CM-1: Policy and Procedures

Quick-reference card

What this control requires

CM-01 requires organizations to develop, document, and disseminate a configuration management (CM) policy and the procedures that enforce it. The policy must cover purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities, and compliance expectations. It also needs to align with every applicable law, executive order, directive, regulation, and standard your organization operates under.

Without documented CM policy and procedures, your team has no shared baseline for how systems should be configured, who approves changes, or how deviations get handled. The control also requires a designated official to own the policy and procedures lifecycle, ensuring both documents get reviewed and updated at a defined frequency and whenever triggering events occur. Those events include assessment findings, security incidents, or changes to the regulatory landscape. You can find the full NIST SP 800-53 framework index for additional context on how CM-01 fits into the broader control catalog.

In practice, CM-01 is the foundational control for the entire configuration management family. Every other CM control depends on the policy and procedures CM-01 establishes. Simply restating control language doesn’t satisfy the requirement. Your policy must reflect actual organizational decisions about scope, authority, and process.

Why it matters

Most audit findings in configuration management trace back to missing, outdated, or generic policy documents that don’t reflect how the organization actually operates. CM-01 sits at the governance layer, which means a gap here cascades into every downstream CM control your assessor evaluates.

Failing to maintain CM policy and procedures doesn’t just create a single finding. It signals to auditors and assessors that your organization lacks the governance structure to manage system configurations consistently, and it calls into question every technical CM control you claim to have in place.

Specifically, your organization’s risk management strategy directly shapes what your CM policy should contain. Security and privacy programs should collaborate on policy development rather than maintaining parallel documents. Organization-level policies are generally preferable because they reduce redundancy and conflicting guidance across mission areas and individual systems.

Where this gap matters most is in third-party relationships, vendors without documented CM policies can’t demonstrate that their configuration practices are repeatable, auditable, or aligned with your contractual requirements. A thorough compliance checklist helps you verify these governance fundamentals before assessing technical controls.

The following threat vectors become relevant when CM policy and procedures are weak or absent:

• Unauthorized configuration changes go undetected because no policy defines change approval workflows or monitoring requirements
• Inconsistent system baselines emerge across environments because procedures don’t specify how configurations should be documented and enforced
• Regulatory non-compliance surfaces when policies fail to incorporate changes to applicable laws, directives, or standards
• Accountability gaps form where no designated official owns the CM lifecycle, allowing policy drift and unreviewed procedures
• Audit failure escalates when assessors identify a CM-01 gap and expand their scope to question all related CM controls

How to implement

Organizations typically struggle with CM-01 not because writing policy is technically difficult, but because they treat it as a checkbox exercise. Generic policy templates copied from the internet rarely reflect your actual configuration management practices, organizational structure, or risk environment.

For your organization

Start by identifying the designated official who will own your CM policy and procedures. This person doesn’t need to write every word, but they must have the authority and accountability to approve, disseminate, and enforce the documents.

The result of that designation is a policy that must address each assessment objective explicitly. Cover purpose, scope, roles, responsibilities, management commitment, coordination among entities, and compliance requirements. Tailor these sections to your actual organizational structure rather than using abstract language that could apply to any company.

Specifically, each procedure should map to a CM control in the CM control family. Procedures should describe how policies and controls are implemented and can target specific roles or organizational functions. A configuration analyst needs different procedural guidance than a system owner or authorizing official.

In practice, you also need to define your review cycle and triggering events. Most organizations review CM policy annually, but you should also update following assessment or audit findings, security incidents, and changes to applicable laws or regulations. Document these triggers in the policy itself so the review cadence is self-reinforcing.

Specifically, your CM policy should align with your organization’s risk management strategy. The policy should reference your risk tolerance, prioritization approach, and any configuration management best practices your teams follow.

Common mistakes to avoid:

• Restating NIST control language verbatim instead of documenting actual organizational decisions
• Failing to name specific roles and assign clear responsibilities
• Writing procedures that describe what to do but not who does it, when, or how outcomes are verified
• Skipping the dissemination step, leaving approved policy sitting in a document repository no one can find
• Treating CM policy as a standalone document when it should reference or integrate with your broader security and privacy program policies

For your vendors

When evaluating a vendor’s CM-01 compliance, you’re assessing whether they have the governance foundation to manage configurations consistently. Without documented policy and procedures, any technical CM evidence they provide lacks institutional backing.

Specifically, request the vendor’s current configuration management policy and verify it addresses purpose, scope, roles, responsibilities, management commitment, coordination, and compliance with applicable regulations. Check that the policy names a designated official responsible for its maintenance.

In practice, you should also ask for the documented review and update history. A policy last reviewed three years ago, or one with no revision history at all, suggests the vendor treats governance documentation as a one-time exercise. Confirm that triggering events for updates are defined and have been acted upon when relevant events occurred.

In practice, that evaluation also means requesting the vendor’s CM procedures and validating that they go beyond generic descriptions. Procedures should specify how configuration changes are proposed, approved, implemented, and verified within the vendor’s environment. They should also describe how the vendor coordinates CM activities across teams or business units.

Beyond the CM policy itself, review whether it aligns with the vendor’s broader security and privacy program documentation. Policies that contradict each other or exist in isolation are a sign of fragmented governance.

Red flags to watch for:

• No named policy owner or designated official
• Policy documents with no revision history, review dates, or version control
• Procedures that restate control requirements without describing actual implementation steps
• CM policy that doesn’t reference applicable laws, regulations, or contractual obligations
• Separate, conflicting security and privacy policies with no coordination between them

Frequently asked questions

What is NIST SP 800-53 CM-01?

CM-01 requires organizations to develop, document, and disseminate a configuration management policy and supporting procedures that cover purpose, scope, roles, responsibilities, and compliance alignment. The policy establishes the governance foundation for every other control in the CM family. A designated official must own both the policy and procedures, reviewing and updating them at a defined frequency and in response to triggering events such as audit findings or regulatory changes.

What happens if CM-01 is not implemented?

Without a documented CM policy and designated policy owner, your organization can’t demonstrate governance over configuration management activities to auditors or assessors. This gap typically escalates beyond a single finding because assessors view CM-01 as the foundation for all other CM controls. In practice, missing CM procedures mean configuration changes lack defined approval workflows, review cadences go undocumented, and accountability for CM activities remains unassigned.

How do you audit CM-01?

Auditing CM-01 starts with verifying that a documented configuration management policy exists, names a designated official, and addresses all required elements including purpose, scope, roles, management commitment, coordination, and regulatory alignment. Assessors then review the policy’s revision history to confirm it has been updated at the defined frequency and in response to triggering events like security incidents or changes to applicable laws. They also examine CM procedures to verify they describe actual implementation steps mapped to specific CM controls rather than restating control requirements verbatim.

What should a configuration management policy include?

A configuration management policy should define the purpose and scope of CM activities, assign specific roles and responsibilities, document management commitment, establish coordination requirements across organizational entities, and demonstrate compliance with applicable laws, directives, and standards. The policy must also specify a review and update cadence tied to both a recurring schedule and event-driven triggers. Effective CM policies go beyond generic statements by reflecting the organization’s actual risk management strategy and naming the official accountable for maintaining both the policy and its supporting procedures.
