Cybersecurity governance maturity

Cybersecurity governance maturity (C2M2-01) requires you to formally define who owns cybersecurity capability maturity, who approves targets, and how progress is governed, measured, and reported. To operationalize it quickly, assign executive accountability, establish a maturity scoring owner, set recurring governance checkpoints, and retain board/leadership-ready evidence that decisions were made and followed. ¹

Key takeaways:

• Name accountable owners for cybersecurity maturity outcomes, not just security operations. ¹
• Establish governance checkpoints that review maturity scores, gaps, and remediation decisions on a recurring cadence. ¹
• Keep audit-ready artifacts: scope, RACI, minutes, scorecards, and decision logs that show accountability in action. ¹

C2M2 governance maturity is a “show your work” requirement: you need a defined governance model and clear accountability for cybersecurity capability maturity, and you need evidence that the model operates. The fastest way to fail this requirement is to treat maturity scoring as a one-time assessment owned by a single security analyst with no executive sponsorship, no decision rights, and no record of how maturity results changed priorities.

For a CCO, GRC lead, or security governance owner, the practical goal is straightforward: set decision rights around maturity targets (what “good” looks like), resource decisions (what gets funded), and exception handling (what risks you accept). Then create a repeatable operating rhythm that ties maturity results to action items, owners, and due dates.

This page translates the C2M2-01 requirement into implementable steps you can execute in an enterprise IT environment, an OT environment, or a mixed critical infrastructure context. It also lists the artifacts examiners, internal auditors, and customer due diligence teams typically request when they ask, “Who owns cybersecurity maturity here, and how do you know it’s improving?” ¹

Regulatory text

Excerpt (C2M2-01): “Define governance and accountability for cybersecurity capability maturity.” ¹

Operator interpretation: You must (1) define a governance structure for cybersecurity capability maturity within the scope you assessed, and (2) assign accountability for both the maturity scoring and the decisions that follow from it. Governance has to be more than a chart; it should create decision rights, an escalation path, and a recurring mechanism to review maturity results and drive remediation. ¹

What an operator must do to satisfy the text:

• Define who is accountable for maturity outcomes (executive ownership) and who is responsible for running the maturity process (program ownership). ¹
• Define how maturity is measured, reviewed, approved, and updated (governance checkpoints). ¹
• Maintain evidence that governance operates: meetings occur, scores are reviewed, decisions are recorded, and actions are tracked to closure. ¹

Plain-English requirement (what this means)

You need a documented and functioning governance model that makes cybersecurity maturity a managed program with owners, approvals, and follow-through. If someone asks why your maturity score is what it is, or why you accepted a gap, you can point to named decision-makers and dated decisions, not tribal knowledge.

Who it applies to (entity + operational context)

This applies when your organization has adopted C2M2 for a defined scope and is assessing cybersecurity capability maturity within that scope. ¹

Typical in-scope contexts:

• Critical infrastructure operators and energy sector organizations using C2M2 as a maturity model. ¹
• A scoped business unit (e.g., generation, transmission, corporate IT), a function (e.g., identity, incident response), or an OT environment where maturity is assessed and improved. ¹

Practical scoping note: governance maturity should match the scope boundary. If you score maturity for OT but only govern improvements through an IT steering committee with no OT leadership, your governance will look misaligned during audit.

What you actually need to do (step-by-step)

Step 1: Define the maturity program scope and authority

• Document the assessed scope (systems, environment, org units) and who has authority to set targets and approve remediation within that scope.
• State what maturity model outputs you produce (e.g., domain scores, gap register, improvement roadmap) and who consumes them.

Deliverable: “C2M2 Maturity Governance Charter” (1–3 pages) describing scope, authority, and outputs. ¹

Step 2: Assign accountability (RACI that matches real decision rights)

You need two layers of ownership:

• Accountable executive: owns the outcome and accepts residual risk for maturity gaps in scope.
• Program owner: runs the maturity scoring process, coordinates evidence collection, and maintains the improvement backlog.

Then assign supporting roles (responsible/consulted/informed) across security, IT, OT, risk, compliance, internal audit, and key operations leaders.

Minimum RACI fields to define:

• Approve maturity targets by domain
• Approve risk acceptance / exceptions for maturity gaps
• Own maturity scoring methodology and evidence standards
• Own remediation execution (by control domain)
• Report maturity status to leadership

Deliverable: RACI matrix with named roles and alternates. ¹

Step 3: Establish governance checkpoints and maturity score ownership

C2M2-01 is easiest to evidence when you formalize checkpoints:

• A recurring review of maturity results and changes
• A decision forum to approve remediation priorities and risk acceptance
• A reporting path to senior leadership

Operational pattern that works in practice:

• A “Cybersecurity Maturity Working Group” prepares scores, evidence, and recommendations.
• A “Cybersecurity Governance Committee” approves targets, priorities, and exceptions.
• Executive/board reporting receives a summarized scorecard and top decisions.

Deliverables:

• Meeting charter for each forum (membership, quorum/decision rights, agenda template)
• Owner for the maturity scorecard and the source-of-truth repository ¹

Step 4: Define the scoring and change-control mechanics

Auditors commonly probe whether maturity scoring is consistent and repeatable.

Document:

• How scores are determined (evidence thresholds, review/approval steps)
• How disagreements are resolved (tie-breaker role, escalation)
• How often scores are refreshed (event-driven refresh is acceptable if defined)
• How changes are versioned and approved (simple change log is enough)

Deliverables:

• Scoring procedure
• Score change log with approvals
• Evidence standard (what “good evidence” looks like per domain) ¹

Step 5: Link maturity results to action (backlog + accountability)

Governance maturity is weak if it stops at scoring.

Create:

• A maturity gap register (gap, domain, severity/priority, owner, target state, dependencies)
• A remediation roadmap (sequenced initiatives)
• A risk acceptance process for gaps you will not remediate soon (who approves, rationale, review trigger)

Deliverables:

• Maturity improvement backlog in your GRC ticketing system (or equivalent)
• Risk acceptance log tied to maturity gaps ¹

Step 6: Prove operation with reporting that leadership can use

Build a scorecard that supports decisions, not vanity metrics:

• Domain-level maturity scores and trend
• Top gaps that constrain maturity improvement
• Decisions required (funding, staffing, architecture direction, third party constraints)
• Exceptions/accepted risks and review dates (if you use dates, make them internal policy-driven)

Deliverables:

• Quarterly (or governance-defined) maturity scorecard pack
• Leadership/committee minutes that record decisions and owners ¹

Required evidence and artifacts to retain (audit-ready)

Keep artifacts in a controlled repository with versioning and access control:

Artifact	What it proves	Common requestor
Governance charter (scope, authority)	Defined governance model and boundaries	Internal audit, customers
RACI with named roles	Accountability and decision rights	Regulators, auditors
Committee charters + agendas	Governance checkpoints exist	Auditors
Meeting minutes with decisions	Governance operates; decisions are traceable	Auditors, regulators
Maturity scorecards (current + prior)	Ownership of scoring, trending	Leadership, exam teams
Scoring procedure + evidence standard	Repeatability and consistency	Audit, assurance
Gap register + remediation backlog	Conversion of assessment into action	Risk committees
Risk acceptance / exception log	Accountable risk decisions	Regulators, customers

Common exam/audit questions and hangups

1. “Who is accountable for maturity improvement?” They want a named executive role and delegated program ownership, not a generic “security team.”
2. “Show me the governance cadence.” Expect requests for agendas, minutes, and decision logs that map to maturity outputs.
3. “How do you prevent score inflation?” Be ready to show evidence standards and an approval process for score changes.
4. “How does this tie to budget and prioritization?” Auditors look for decisions that move resources toward maturity gaps.
5. “What happens when the business accepts a maturity gap?” If you accept risk, show who approved it and how you revisit it.

Frequent implementation mistakes (and how to avoid them)

• Mistake: Governance exists only on paper. Fix: require minutes and decision tracking as part of the maturity process definition. ¹
• Mistake: No single owner for the maturity score. Fix: assign score ownership explicitly and treat the scorecard as a controlled record. ¹
• Mistake: Misaligned scope. Fix: align committee membership and decision rights to the assessed environment (especially IT vs OT).
• Mistake: Scores without a remediation mechanism. Fix: every material gap needs an owner, an action path (remediate/accept/transfer), and reporting.
• Mistake: Treating third parties as out of scope by default. Fix: if third parties materially affect in-scope environments (managed security, OT vendors, SaaS), track their constraints as maturity blockers and route through governance.

Enforcement context and risk implications

No public enforcement cases were provided in the source catalog for this requirement, so you should treat “enforcement” here as indirect: governance maturity gaps commonly surface during internal control testing, audits, customer diligence, and regulator reviews as an inability to justify access decisions and risk acceptance. Poorly evidenced governance can leave inappropriate access in place and makes decisions difficult to defend under scrutiny. ¹

Practical risk framing you can use with leadership:

• Governance maturity reduces “single point of failure” risk where one team informally decides maturity posture.
• Evidence reduces dispute risk: you can show who approved targets and why exceptions were accepted. ¹

A practical 30/60/90-day execution plan

Days 0–30: Stand up ownership and the minimum governance spine

• Appoint the accountable executive and the maturity program owner.
• Write the governance charter (scope, authority, outputs).
• Publish the RACI and confirm decision rights with stakeholders.
• Create scorecard template, gap register template, and minutes template.
• Hold the first governance checkpoint meeting; capture minutes and actions. ¹

Days 31–60: Make scoring repeatable and connect it to action

• Finalize scoring procedure and evidence standards.
• Establish the maturity repository and version control rules.
• Run (or refresh) maturity scoring for the agreed scope using the evidence standard.
• Populate the maturity improvement backlog with owners and planned actions.
• Define the risk acceptance workflow for maturity gaps and start logging approvals. ¹

Days 61–90: Prove operation and management reporting

• Run the second governance checkpoint; show trend, decisions, and closure progress.
• Produce an executive-ready maturity report and align it to resource decisions.
• Perform a lightweight internal review: verify that artifacts exist and map to the requirement.
• If you use Daydream to manage controls and evidence, configure a dedicated evidence collection workflow for committee minutes, scorecards, and decision logs so audits become exportable instead of manual. ¹

Frequently Asked Questions

Do we need a board committee to meet C2M2 governance maturity?

C2M2-01 requires defined governance and accountability, not a specific committee type. If your scope and risk profile warrant board visibility, route maturity reporting through existing risk governance and keep evidence of decisions. ¹

Can security own the maturity score if IT/OT owns remediation?

Yes, if decision rights are explicit. Assign security as the score owner and assign remediation owners by domain, with a governance forum that resolves disputes and approves exceptions. ¹

How do we handle disagreements about maturity scores?

Document a scoring procedure with an escalation path and a final approver role. Keep a score change log that records what changed, why, and who approved it. ¹

What’s the minimum evidence set auditors usually ask for?

Expect the governance charter, RACI, the latest scorecard, prior scorecards (to show change), meeting minutes with decisions, and a gap register with tracked remediation. ¹

Does this requirement apply if we only ran C2M2 as a one-time assessment?

It applies once you adopt C2M2 for a defined scope and assess maturity; governance maturity then determines whether results drive accountable action. If it was a one-time exercise, you will likely lack evidence of ongoing governance checkpoints. ¹

How should third party dependencies show up in governance maturity?

Track third party constraints as explicit blockers in the gap register (e.g., managed service access, OT vendor remote access) and route risk decisions through the same governance approvals you use for internal gaps.
