Security Roles and Responsibilities

“Security roles and responsibilities” fails in predictable ways: the policy is vague (“IT is responsible for security”), it doesn’t cover contractors or business users, or it exists but nobody can show a reliable acknowledgment trail. PCI DSS 4.0.1 makes this an explicit requirement: you need defined roles and responsibilities for all personnel, plus evidence that personnel are aware of and acknowledge their responsibilities (PCI DSS v4.0.1 Requirement 12.1.3).

For a Compliance Officer, CCO, or GRC lead, the fastest path is to treat this as a governance control with operational hooks. The policy is the authority source, but the “system of record” is usually (1) an HR identity feed or roster, (2) a role-based responsibility matrix (RACI-style), and (3) an attestation workflow tied to onboarding and a recurring cycle. Your goal is to make it hard for anyone with access to the cardholder data environment (CDE), or who can affect it, to avoid receiving, understanding, and acknowledging the responsibilities that apply to them.

This page gives requirement-level implementation guidance, evidence expectations, and audit pitfalls so you can implement quickly and defend it cleanly in a PCI assessment.

Regulatory text

Requirement (verbatim): “The information security policy clearly defines information security roles and responsibilities for all personnel, and all personnel are aware of and acknowledge their information security responsibilities.” (PCI DSS v4.0.1 Requirement 12.1.3)

What an operator must do:

1. Define roles and responsibilities in the policy in a way that is unambiguous and testable. “Clearly defines” means a reader can determine who does what without guessing.
2. Cover all personnel (employees, contractors, temps, interns, and other workforce members) who can affect the security of the CDE or connected systems.
3. Create an awareness + acknowledgment mechanism that produces evidence. Acknowledgment is typically an attestation (electronic or signed) that is attributable to an individual and time-bound.
4. Maintain it as a living control: when roles change, responsibilities change, or teams reorganize, the policy and mapping must stay current and approved.

Plain-English interpretation

This requirement is about accountability. You must be able to point to a written policy that assigns security duties to specific roles across the organization, then show that every person knows what they are responsible for and has acknowledged those responsibilities (PCI DSS v4.0.1 Requirement 12.1.3).

If your organization has “security owned by one team,” you will still fail if other roles have security-relevant actions (access provisioning, change approvals, incident reporting, handling payment data, managing third parties) but those duties aren’t spelled out and acknowledged.

Who it applies to

Entities: Merchants, service providers, and payment processors that store, process, or transmit account data, plus service providers whose people/processes/systems can affect CDE security (PCI DSS v4.0.1 Requirement 12.1.3; PCI DSS v4.0.1).

Operational context (practical scoping):

• Anyone with logical or physical access to CDE systems, networks, logs, consoles, backups, or security tooling.
• Anyone who can change systems connected to the CDE (engineering, DevOps, network, SRE, database).
• Functions that influence security outcomes (HR onboarding/offboarding, procurement/third-party management, legal/compliance, customer support handling payment-related workflows).
• Third-party personnel if they operate systems or processes that can affect the CDE; your contracts and onboarding processes should address awareness and acknowledgment expectations for them in a workable way.

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

1) Build a role inventory tied to real access

• Pull an authoritative list of roles from HR and IT: departments, job families, and privileged access groups.
• Identify roles that touch payment flows, CDE systems, or security tooling.
• Don’t rely on titles alone. Map to functions (e.g., “Linux admin with production access”) because titles vary.

Output: “In-scope personnel roles list” with an owner and last-updated date.

2) Draft a responsibilities matrix (RACI-style)

Create a table that is easy to test. Keep it short enough that people read it.

Minimum columns most teams need:

• Role
• Security responsibilities (bulleted, specific verbs)
• Systems/processes impacted (CDE, log management, access control, incident response, change management)
• Required training/reading
• Acknowledgment required (yes/no, method)

Examples of role responsibilities that assessors expect to see described somewhere:

• All personnel: report suspicious activity, follow acceptable use, protect credentials, handle account data properly.
• Managers: ensure staff complete training and attestations; approve access based on job need.
• Access administrators: provision/deprovision within defined SLAs; enforce least privilege; document approvals.
• Developers: follow secure coding standards; remediate findings; do not store prohibited data.
• Security team: define standards; monitor; investigate; run incident response.
• Third-party management/procurement: ensure third parties meet security requirements for any service that can affect CDE security.

Output: Security roles and responsibilities matrix version-controlled and approved as a governed artifact.

3) Update the information security policy to “clearly define” ownership

Your policy should:

• Reference (or embed) the roles/responsibilities matrix.
• Name policy owners (security, compliance) and approval authority.
• Define how updates happen when org structure changes.
• Include language that the responsibilities apply to all personnel and require acknowledgment (PCI DSS v4.0.1 Requirement 12.1.3).

Practical drafting tip: Write responsibilities as obligations with action verbs (“must review,” “must approve,” “must report”) rather than aspirational statements.

4) Implement awareness + acknowledgment workflows

You need two channels: initial and recurring.

• Onboarding (initial awareness):

  • Assign required training and policy reading based on role.
  • Collect an acknowledgment in your HRIS, LMS, or e-sign tool.
  • Block production/CDE access until acknowledgment is completed (where feasible). If you can’t block, require a compensating manager sign-off and track exceptions.

• Recurring (ongoing acknowledgment):

  • Run periodic attestations for all personnel (and role-targeted ones for privileged roles).
  • Re-attest on major policy updates, role changes, or after incidents that reveal a gap.

Output: Attestation records that are attributable, time-stamped, and reportable by population and by exception.

5) Make it provable in day-to-day operations

Assessors and internal audit will look for signs the policy is used operationally, not stored in a folder. Wire responsibilities into:

• Ticket templates for access requests (approver accountability).
• Change management checklists (who signs off, who tests, who validates).
• Incident response runbooks (who declares, who communicates, who collects evidence).
• Performance goals for privileged roles (optional, but effective if your culture supports it).

6) Centralize evidence for the assessment package

Put everything in a single evidence folder or GRC control record:

• Current policy and prior versions
• Approval history
• Role matrix
• Training/attestation exports
• Exceptions and remediation

Daydream is often the natural place to keep this organized because you can maintain version history, map responsibilities to control owners, and store operating artifacts in one record for faster PCI readiness reviews.

Required evidence and artifacts to retain

Keep evidence that supports both design (the policy defines roles) and operation (people acknowledged and follow it):

Policy + governance

• Information security policy with roles/responsibilities section (PCI DSS v4.0.1 Requirement 12.1.3)
• Document owner, approver, approval date, and review cadence
• Version history and change log

Role definition artifacts

• Roles/responsibilities matrix (RACI-style)
• Org chart or functional ownership chart for security-relevant processes
• Access group to role mapping for privileged roles (where available)

Awareness/acknowledgment

• LMS completion reports for policy/security training
• Signed/electronic attestations with timestamps
• New hire onboarding checklist showing policy acknowledgment
• Contractor acknowledgment process (contract clause + evidence of acceptance, or comparable method)

Operational proof

• Sample access request tickets showing approvals per defined roles
• Sample change tickets showing assigned responsibilities
• Incident records showing correct escalation/ownership

Common exam/audit questions and hangups

Expect these lines of questioning in PCI testing:

• “Show me where the policy defines responsibilities for non-IT roles.”
• “How do contractors acknowledge responsibilities?”
• “How do you know everyone acknowledged, not just employees in one system?”
• “What happens when someone changes roles or transfers teams?”
• “How do you ensure managers enforce completion?”
• “Prove the policy was approved and communicated.”

Hangups that slow assessments:

• Role definitions exist, but the policy does not clearly point to them.
• Attestations exist, but you can’t tie them to a complete population (“all personnel”) reliably.
• Evidence is scattered across HR, ITSM, LMS, and shared drives with no control owner who can produce it quickly.

Frequent implementation mistakes (and how to avoid them)

Mistake	Why it fails	Fix
“IT is responsible for security” policy language	Not “clearly defines” roles; too generic to test	Create a role matrix with specific obligations by function (PCI DSS v4.0.1 Requirement 12.1.3)
Only security team signs acknowledgment	Requirement says all personnel	Use HR roster as the population baseline and track completion exceptions
Acknowledgment is a one-time email	Hard to prove, not repeatable	Use LMS/HRIS/e-sign with time-stamped attestations and reporting
Contractors excluded	Contractors can affect CDE security	Add contractor onboarding/renewal acknowledgment requirements and retain evidence
Policy updated but no re-attestation	People may not know changed duties	Trigger re-acknowledgment on major updates and role changes

Risk implications (why assessors care)

Unclear roles create control gaps: access approvals happen without accountable approvers, incident escalation stalls, patches and configuration changes lack ownership, and third-party access drifts. In PCI terms, those gaps often surface as failures in access control, change management, logging/monitoring, and incident response testing. Requirement 12.1.3 is a governance dependency; if it’s weak, multiple downstream requirements become harder to defend (PCI DSS v4.0.1).

Practical 30/60/90-day execution plan

First 30 days (stabilize and publish)

• Assign an executive owner and a working owner for the policy and role matrix.
• Inventory roles that impact the CDE and connected systems.
• Draft the roles/responsibilities matrix and update the information security policy to reference it (PCI DSS v4.0.1 Requirement 12.1.3).
• Choose the acknowledgment mechanism (LMS/HRIS/e-sign) and define the population source of truth.

Days 31–60 (operationalize and collect evidence)

• Launch acknowledgments for all in-scope personnel; track exceptions with owner and due date.
• Implement onboarding steps to assign training and require acknowledgment before granting sensitive access.
• Run a pilot evidence pull: policy version, approvals, role matrix, attestation export, and a small sample of operational tickets.

Days 61–90 (audit hardening and continuous operation)

• Expand role mapping to cover edge cases (shared services, offshore teams, incident comms, procurement/third-party management).
• Document your “change triggers” (re-orgs, policy updates, role transfers) and what re-acknowledgment happens.
• Build an assessor-ready evidence packet in a single system of record (Daydream or equivalent), with clean version history and exports.
• Conduct an internal walkthrough: pick a random person in a privileged role and prove end-to-end that they were informed, acknowledged, and operate according to defined responsibilities.

Frequently Asked Questions

Do we need a separate policy for roles and responsibilities?

No. PCI DSS asks that the information security policy clearly defines roles and responsibilities and that personnel acknowledge them (PCI DSS v4.0.1 Requirement 12.1.3). Many teams meet this by embedding a roles section in the main policy and attaching a referenced matrix.

Does “all personnel” include contractors and temporary staff?

Yes, if they can affect the security of the CDE or connected systems. Make contractor acknowledgment part of onboarding or contract acceptance, and retain evidence that you can produce during assessment (PCI DSS v4.0.1 Requirement 12.1.3).

What counts as “acknowledge” in practice?

A time-stamped, attributable record that a person agreed to follow the policy and their role responsibilities. Common approaches are LMS attestations, HRIS acknowledgments, or an e-sign workflow (PCI DSS v4.0.1 Requirement 12.1.3).

We have a RACI in Confluence. Is that enough?

It can be, if it is controlled (version history, approvals) and clearly tied to the information security policy, plus you can show personnel awareness and acknowledgment. Assessors will test clarity and evidence, not your tooling (PCI DSS v4.0.1 Requirement 12.1.3).

How do we handle frequent reorganizations and role changes?

Define triggers: role transfer, privilege change, and major policy updates should prompt re-assignment of training and re-attestation. Keep the role matrix mapped to functions/access groups rather than job titles to reduce churn.

What will an assessor sample to test this requirement?

They typically sample the policy, the role/responsibility definitions, and a set of personnel to confirm they acknowledged responsibilities and fall into the correct role mapping. Be ready to show the population, the completion report, and exceptions with remediation notes (PCI DSS v4.0.1 Requirement 12.1.3).
