Key Takeaways: ISO 27001 Annex A 5.2 Information Security Roles and Responsibilities

ISO 27001 Annex A 5.2 requires organizations to define and allocate information security roles and responsibilities based on their specific needs. This control ensures that everyone, from the Board of Directors to the newest employee, knows exactly what is expected of them regarding data protection. Without clearly defined roles, critical security tasks (like incident response or patch management) can easily fall through the cracks, leading to audit failures and security breaches.

  • You must clearly define who is in charge of information security. This means spelling out what each person’s job is.
  • After defining the roles, you need to assign people to them and write everything down. This makes sure everyone knows their part.
  • The main leaders in the company are responsible for making sure these roles are set up correctly and that people have what they need to do their jobs.

Core requirements for compliance include:

  • Explicit Definition: You must clearly document what each security role does. This is typically achieved through a Roles and Responsibilities Matrix or by including security duties within standard job descriptions.
  • Allocation to Competent Personnel: Roles must be assigned to individuals who have the skills and authority to perform them. In smaller organizations, it is common (and acceptable) for one person to hold multiple roles.
  • Management Oversight: Senior leadership is accountable for ensuring these roles are correctly set up and adequately resourced with the necessary tools, time, and training.
  • Avoidance of Conflict: Responsibilities should be allocated to prevent “conflict of interest.” For example, the person who implements a security change should ideally not be the only person who approves it.
  • Regular Review: Roles and responsibilities must be reviewed at least annually or whenever there is a significant change in the organization, such as a restructuring or a major technology shift.

Audit Focus: Auditors will look for “The Ownership Gap”:

  1. Staff Interviews: “Who is responsible for managing your firewall?” or “What is your specific role if a data breach occurs?”
  2. Evidence of Assignment: “Show me where your Chief Information Security Officer (CISO) role is formally documented and who has been appointed to it.”
  3. Resource Support: They will check if the people assigned to these roles have the actual time and budget to carry them out.

What is ISO 27001 Annex A 5.2?

ISO 27001 Annex A 5.2 Information Security Roles and Responsibilities is about ensuring the you have the required roles for information security and that those roles and responsibilities are documented.

It is important to have competent people in place implementing and operating the information security management system.

ISO 27001 Annex A 5.2 is an ISO 27001 control that requires an organisation to define information security roles and responsibilities and allocate those to people.

The current version of the ISO 27001 standard is ISO/IEC 27001:2022, which came out in October 2022. In this standard, the control is called “Information Security Roles and Responsibilities”

ISO 27001 Annex A 5.2 Purpose

The purpose of ISO 27001 Annex A 5.2 is to ensure that a defined, approved and understood structure is in place for the implementation and operation of the information security management system.

ISO 27001 Annex A 5.2 Control Objective

The official goal in the standard is simple: You should clearly define and give out all information security jobs and tasks based on your company’s needs.

ISO 27001 defines ISO 27001 Annex A 5.2 Roles and Responsibilities as:

Information security roles and responsibilities should be defined and allocated according to the organisation needs.

ISO 27001 Annex A 5.2 Implementation Guide

To implement this control you should have clear plans and policies. Here are some important steps:

  • work out what roles you need
  • decide on what responsibilities those roles have
  • pick people in your organisation and assign those roles and responsibilities to them
  • document it
  • publish it
  • have them acknowledged by staff
  • review them at regular intervals

How to document roles and responsibilities

You are going to need copies of the relevant standards for information security.

You then need to work through policies, research organisational best practice, and work out exactly what information security roles and responsibilities you need.

When you implement it, depending on the size of your organisation, it is not uncommon for one person to hold more than one role.

You may be thinking, if it is one person doing all the work why do I need to document so many roles?

The short answer is because the ISO 27001 standard requires it and if you are going for ISO 27001 certification then you need it.

The longer answer is that as you grow, more people will take on these roles and spread the work load.

How to identify the mandatory roles you need

You start with the list of controls from Annex A that you have chosen. Then, you will figure out what roles are needed for each of those controls.

Once you have identified all the roles, you will assign them to people in your organisation. It’s important to make sure the person you choose is able to perform the role and that their new duties won’t conflict with their current responsibilities.

Can one person hold more than one role?

If you work in a small business, you might wonder if you need all these roles and if one person can handle multiple roles. The answer is yes, you do need certain specific roles, and yes, one person can indeed hold more than one role.

What is an ISO 27001 Management Review Team?

This group sits above the information security management system. It has very specific requirements and a defined role. The team’s responsibilities include:

How to implement ISO 27001 Annex A 5.2

Implementing ISO 27001 Annex A 5.2 requires a transition from general security awareness to defined technical accountability. By formalising exactly who is responsible for specific security outcomes, an organisation eliminates the “security gap” where critical tasks are overlooked. This action-oriented guide outlines the necessary steps to provision roles, formalise authorities, and ensure that your Information Security Management System (ISMS) has the human infrastructure required for compliance.

1. Formalise Top Management Accountability

Establish the foundation of the ISMS by documenting the ultimate accountability of the Board or Executive team. This action results in a governance layer that ensures security objectives are aligned with business goals and that adequate resources are provisioned.

  • Incorporate information security performance into the Board of Directors’ annual agenda.
  • Document the appointment of a member of top management as the ultimate “Accountable” party for the ISMS.
  • Formalise the approval process for the Information Security Policy and Risk Treatment Plan.

2. Provision an Information Security Lead Role

Assign the day-to-day operation of the ISMS to a competent individual, such as a CISO or Information Security Manager. This result-focused step ensures that a central point of contact exists for all security-related decision-making and reporting.

  • Define the specific authority of the Security Lead to halt business processes if significant risks are identified.
  • Establish direct reporting lines from the Security Lead to top management to ensure unbiased risk communication.
  • Map specific Identity and Access Management (IAM) administrative roles to this position to facilitate oversight.

3. Execute a RACI Matrix for Security Processes

Identify every security control within your Statement of Applicability and assign specific roles to each. This action results in a clear map of who is Responsible, Accountable, Consulted, and Informed for every technical and organisational control.

  • Utilise a formal RACI matrix to define ownership of tasks such as backup verification, log reviews, and patch management.
  • Identify “Asset Owners” for every item in your Information Asset Register as required by Annex A 5.9.
  • Document “Rules of Engagement” (ROE) for third-party contractors to ensure they understand their specific security boundaries.

4. Formalise Security Duties in Job Descriptions

Integrate specific security requirements into the employment lifecycle by updating standard job descriptions. This action results in security being a contractual obligation for all staff rather than an optional activity.

  • Include “Adherence to the Acceptable Use Policy” as a core requirement for all personnel roles.
  • Define specific technical security duties for IT staff, such as firewall configuration or vulnerability remediation.
  • Establish a formalised sign-off process where employees acknowledge their specific security responsibilities upon hire and during annual reviews.

5. Execute Periodic Role and Authority Reviews

Perform a bi-annual review of all assigned security roles to ensure they remain appropriate as the organisation scales. This result-oriented step ensures that “privilege creep” is identified and that responsibilities are redistributed following organisational changes.

  • Review and update the ISMS organisational chart to reflect recent joiners, movers, and leavers.
  • Verify that individuals assigned to specific security roles still possess the necessary competence and training.
  • Document the results of these reviews as mandatory evidence for your ISO 27001 Stage 2 audit.

  • Gather their perspectives on the effectiveness of the organisation’s approach to defining, assigning, and managing information security roles and responsibilities.
  • Verify that the organisation’s approach to roles and responsibilities complies with all applicable laws and regulations.

10. Evaluate Overall Effectiveness

  • Assess the overall effectiveness of the organisation’s approach to defining, assigning, and managing information security roles and responsibilities.
  • Identify areas for improvement and make recommendations for enhancing the effectiveness of the system.

How to pass the ISO 27001 Annex A 5.2 audit

To pass the audit of ISO 27001 Annex A 5.2 you will make sure that you:

  • Write an ISO 27001 roles and responsibilities document
  • Set out what roles you have and the responsibilities those roles undertake
  • Create an organisation of the roles to show how they work together
  • Assign people to those roles and document when they were assigned
  • Review and approve the roles and responsibilities document
  • Publish the roles and responsibilities document to a place everyone that needs to see them can see them
  • Plan to review your roles and responsibilities at least annually or if significant change occurs
  • Keep records of your review and the changes

What an auditor looks for

The audit is going to check a number of areas for compliance with ISO 27001 Annex A 5.2 Roles and Responsibilities. Lets go through them:

1. That you have documented your roles and responsibilities

What this means is that you will have a document that sets out what the roles and responsibilities are that are involved in the ISO 27001 implementation and operation of your information security management system. What needs doing and what will be done.

2. That you have have allocated your roles and responsibilities

For the roles and responsible that you have defined and documented you are going to allocate people to them to do the work. Has each defined role been allocated to someone and can you say who if asked?

3. That allocated people are competent

We allocate people but not just any old people. The people that do the role have to be competent to perform the role. This usually means the checking of qualifications, training and / or experience.

Top 3 ISO 27001 Annex A 5.2 Mistakes and How to Fix Them

In my experience, the top 3 mistakes people make for ISO 27001 Annex A 5.2 Roles and Responsibilities are:

1. You have not documented the actual roles you require

You need to keep records and minutes of everything. You need a paper trail to show it was done. Make sure you have updated communication plans, minutes of meetings, records of acknowledgement, records of approval. If it isn’t written down it didn’t happen.

2. You allocated a role to someone that no longer works here

Prior to the audit check that roles are assigned to people that actually work here. You will be surprised how often this trips people up. Check!

3. Your document and version control is wrong

Keeping your document version control up to date, making sure that version numbers match where used, having a review evidenced in the last 12 months, having documents that have no ‘comments’ in are all good practices.

Applicability of ISO 27001 Annex A 5.2 across different business models.

Business Type Applicability & Interpretation Examples of Control
Small Businesses

“Multiple Hats.” You don’t need a dedicated CISO. Compliance means assigning security duties to existing roles (e.g., Office Manager = Security Lead) and documenting it clearly.

Org Chart Update: Adding “Information Security Manager” as a secondary title to the Director’s job description.
Simple Statement: A policy line stating: “The Business Owner is accountable for all security decisions, while the IT Provider is responsible for patching.”

Tech Startups

Job Descriptions & Contracts. As you hire, roles blur. Compliance requires updating employment contracts to include specific security responsibilities (e.g., “Developer is responsible for secure coding”).

The “Security Champion”: Formally designating one developer in each squad to review PRs for security, even if they aren’t a full-time security engineer.
RACI Matrix: A simple table defining who is Responsible, Accountable, Consulted, and Informed for critical incidents like “Data Breach.”

AI Companies

AI Governance Roles. Beyond standard IT security, you need roles for “Model Safety” and “Data Ethics.” Auditors look for clear ownership of AI-specific risks.

Chief AI Officer (CAIO): Assigning specific accountability for AI bias and safety testing to a senior technical leader.
Data Steward: Designating a specific role responsible for the “Provenance” and “Copyright” of training data, separate from the engineering team.

Applicability of ISO 27001 Annex A 5.2 across different business models.

Fast Track ISO 27001 Annex A 5.2 Compliance with the ISO 27001 Toolkit

For ISO 27001 Annex A 5.2 (Information security roles and responsibilities), the requirement is to clearly define and allocate roles and responsibilities for information security throughout the organization. This ensures accountability and a structured approach to managing your security system.

Compliance Factor SaaS Compliance Platforms High Table ISO 27001 Toolkit Audit Evidence Example
Asset Ownership Rents access to your internal structure; if you cancel the subscription, your documented role assignments and history vanish. Permanent Assets: Fully editable Word/Excel Roles and Responsibilities Matrices that you own forever. A localized “Roles and Responsibilities Matrix” defining specific security duties for the CISO, IT Manager, and HR.
Operational Utility Attempts to “automate” assignments via dashboards that cannot decide who is best suited for manual tasks like physical key management. Governance-First: Provides pre-written role descriptions to formalize your existing team structure into an auditor-ready format. A “Job Description” including specific ISO 27001 clauses to prove that security accountability is part of employment terms.
Cost Efficiency Charges a “Headcount Tax” or “Seat Fee” that scales aggressively as your organization hires more personnel. One-Off Fee: A single payment covers your role governance for 3 roles or 300, with zero recurring costs. Allocating budget to professional security training for staff rather than monthly “governance dashboard” subscription fees.
Structural Freedom Mandates rigid RACI formats that often fail to align with lean startup cultures or complex matrix-management environments. 100% Agnostic: Procedures adapt to your operating style—whether you have one person wearing five hats or specialized teams. The ability to evolve your organizational chart and security committee without reconfiguring a rigid SaaS compliance module.

Summary: For Annex A 5.2, the auditor wants to see that you have a formal matrix of roles and responsibilities and proof that people know what they are. The High Table ISO 27001 Toolkit provides the governance framework to satisfy this requirement immediately. It is the most direct, cost-effective way to achieve compliance using permanent documentation that you own and control.

ISO 27001 Annex A 5.2 FAQ

What is ISO 27001 Annex A 5.2?

ISO 27001 Annex A 5.2 is an organisational control that requires information security roles and responsibilities to be clearly defined and assigned in accordance with the organisation’s needs.

  • Defines who is accountable for specific security tasks.
  • Prevents overlaps or gaps in security management.
  • Ensures that security is integrated into job descriptions.
  • Facilitates effective communication between stakeholders.

Is a CISO mandatory for ISO 27001 compliance?

No, the standard does not mandate a specific “CISO” job title, but it does require that the responsibilities associated with that role are assigned to a competent individual or group.

  • Small organisations may appoint an Information Security Manager instead.
  • Roles can be outsourced to a Virtual CISO (vCISO).
  • Accountability for security must remain within the internal leadership team.
  • The individual assigned must have the authority to enforce security policies.

What is the difference between Clause 5.3 and Annex A 5.2?

Clause 5.3 is a high-level management requirement for assigning authority, whereas Annex A 5.2 is the operational control used to document and implement those specific security roles.

  • Clause 5.3 belongs to the “Leadership” section of the core standard.
  • Annex A 5.2 provides the practical framework for the Statement of Applicability (SoA).
  • Auditors will look for Clause 5.3 during management interviews and Annex A 5.2 during documentation reviews.
  • Both work together to ensure the ISMS is governed and executed.

What are the primary security roles in an ISMS?

Under ISO 27001, security responsibilities are typically distributed across governance, management, and technical layers.

  • Top Management: Responsible for strategy, resources, and commitment.
  • ISMS Manager: Responsible for the day-to-day operation of security controls.
  • Asset Owners: Responsible for the protection of specific data or systems.
  • All Personnel: Responsible for adhering to acceptable use and security policies.

How should security responsibilities be documented?

Organisations must document security roles using formalised records that are accessible and clear to all relevant personnel.

  • Incorporate security duties into standard Job Descriptions (JDs).
  • Utilise a RACI Matrix (Responsible, Accountable, Consulted, Informed) for complex processes.
  • Define roles within the high-level Information Security Policy.
  • Include security accountability in third-party contract agreements.

Who is ultimately responsible for information security?

Top Management, such as the Board of Directors or Executive Leadership, is ultimately accountable for the effectiveness of the Information Security Management System (ISMS).

  • Leadership must promote a culture of security awareness.
  • They are responsible for approving the risk treatment plan.
  • Responsibility for tasks can be delegated, but the accountability for security success cannot.
  • Auditors will test this by looking for management review meeting minutes.
