What is ISO 27001 Clause 5.3?
ISO 27001 Clause 5.3 Roles and Responsibilities is an ISO 27001 control that requires you to define roles and responsibilities relevant to your information security management system (ISMS) and allocate them to people.
Purpose
The purpose of ISO 27001 clause 5.3 is to make sure you have defined, assigned and communicated the roles and responsibilities that you need to run your information security management system to people. This will ensure that the management system is effective.
Definition
The ISO 27001 standard defines ISO 27001 clause 5.3 as:
Top management shall ensure that the responsibilities and authorities for roles relevant to information security are assigned and communicated within the organisation. Top management shall assign the responsibility and authority for: a) ensuring that the information security management system conforms to the requirements of this document b) reporting on the performance of the information security management system to top management.
ISO 27001:2022 Clause 5.3 Organisational roles, responsibilities and authorities
ISO 27001 Roles and Responsibilities Requirement
The requirement for ISO 27001 Clause 5.3 is to make sure that roles, responsibilities and appropriate authority is assigned to people and that this is communicated. We document this in the ISO 27001 Roles and Responsibilities document.
We need to make sure that responsibility is assigned to someone for ensuring the standard is met and for reporting on the effectiveness and performance of the information security management system to the business leaders, which they refer to as ‘top management’.
FREE Training Video
In this free training video I show you how to implement ISO 27001 Clause 5.3 Roles and Responsibilities and how to pass your audit.
Identify the roles that you need
You identify the roles that you need to implement, run and manage your information security management system. To do this you would either take a list of known roles or you would work out what needs doing and the roles that you need to support that.
You are going to work with top management to make sure that you have defined and allocated roles and responsibilities for information security.
The first step is for you to nominate someone to be the information security manager who will be responsible for the information security management system.
Allocate people to roles
With the roles and responsibilities defined and documented it is now time to allocate people to those roles. Roles can be assigned to people outside the organisation if it is practicable and applicable to you.
In a small organisation it may well be the case that one individual is assigned more than one role and that is absolutely fine.
The only requirements is to maintain segregation of duties, which is covered in detail in ISO 27001 Annex A 5.3 Segregation of duties.
You have the following options when assigning people
- Get external help
- Appoint someone internally
- Train someone
You must ensure that the people you assign are competent to take on the roles and that you have not introduced any conflict of interest (ISO 27001 Annex A Control 5.3 Segregation of duties)
Assign the Management Review Team
A management review team has certain responsibilities within the management system.
Document the Management Review Team in the Information Security Roles Assigned and Responsibilities and document that it has responsibility for overseeing the Information Security Management System.
The Management Review Team should be made up of one representative of each of the in scope areas and those representatives should have an assigned deputy. In addition, at least one member of the senior management team and leadership team is part of this Management Review Team.
This group reports to the board and has board representation and certain board designated authority for decision making.
The Management Review Team meeting should meet at least quarterly and follow the agenda as defined in the standard.
Further guidance is provided in the guide How to conduct an ISO 27001 Management Review Meeting.
Typical duties of the Management Review Team include:
- Approval and sign off of policy
- Approval and sign off of processes
- Risk Management Oversight
- Continual Improvement Oversight
- Performance Evaluation of the Information Security Management System (ISMS)
Manage Competence
To manage competence you will complete an ISO 27001 competence matrix.
This is for every member of the management structure, for everybody that’s involved in Information Security Management and its delivery. It will cover everybody documented in the roles and responsibilities document and in the ISO 27001 RASCI Matrix
The basic concept of a Competency Matrix is you are demonstrating that you have the competencies to run an effective management system. You will use it to plan training to address gaps.
Implementation Checklist
Roles and Responsibilities ISO 27001 Clause 5.3 Implementation Checklist:
Identify Key Roles
Determine the essential roles needed for effective ISMS implementation and operation. This includes roles like Information Security Manager, Data Owners, System Administrators, etc.
Challenge: Overlooking crucial roles or creating unnecessary complexity.
Solution: Conduct a thorough analysis of the organisation’s information security needs and structure. Use a RACI matrix (Responsible, Accountable, Consulted, Informed) to define roles and their relationships.
Define Responsibilities for Each Role
Clearly define the specific responsibilities associated with each identified role. What are they expected to do?
Challenge: Vague or overlapping responsibilities, leading to confusion and gaps in coverage.
Solution: Document responsibilities in detail, using clear and concise language. Ensure that each responsibility is assigned to only one role to avoid ambiguity.
Assign Authorities to Match Responsibilities
Grant the necessary authority to individuals so they can effectively carry out their assigned responsibilities. Authority should match the level of responsibility.
Challenge: Giving responsibility without the corresponding authority, hindering performance.
Solution: Clearly define the limits of authority for each role. Ensure that individuals understand their authority levels and are empowered to act within those limits.
Document Roles, Responsibilities, and Authorities
Maintain documented information about the defined roles, responsibilities, and authorities. This can be in the form of job descriptions, role profiles, or a dedicated RACI matrix.
Challenge: Difficulty in keeping documentation up-to-date and accessible.
Solution: Use a centralised document management system to control versions and access. Establish a regular review process to ensure accuracy.
Communicate Roles and Responsibilities
Ensure that all relevant personnel are aware of their own roles and responsibilities, as well as those of others.
Challenge: Employees not understanding their roles or how they contribute to the ISMS.
Solution: Conduct training and awareness programs to communicate roles and responsibilities. Make the documentation easily accessible.
Provide Training and Competence Development
Ensure that individuals have the necessary skills and knowledge to fulfil their assigned responsibilities.
Challenge: Lack of skilled personnel or difficulty in providing adequate training.
Solution: Conduct skills gap analysis and develop training plans to address identified gaps. Provide opportunities for professional development and certifications.
Integrate Roles into ISMS Processes
Ensure that defined roles are integrated into the ISMS processes, such as risk assessment, incident management, and internal audit.
Challenge: Roles not being actively involved in ISMS processes.
Solution: Clearly define the involvement of each role in relevant processes. Include roles in process documentation and training.
Regularly Review Roles and Responsibilities
Periodically review the defined roles and responsibilities to ensure they remain relevant and effective. Business needs and the ISMS itself evolve.
Challenge: Roles becoming outdated or not aligned with current needs.
Solution: Conduct regular reviews, at least annually or more frequently as needed. Involve key stakeholders in the review process.
Address Performance Gaps
Have a process in place to address performance gaps related to information security responsibilities.
Challenge: Difficulty in addressing performance issues or lack of clear performance expectations.
Solution: Establish clear performance expectations for each role. Provide regular feedback and coaching. Implement a performance management process to address performance gaps.
Maintain Organisational Structure Chart
While not strictly required by 27001, a high-level organisational chart showing reporting lines for key security roles can be beneficial.
Challenge: Keeping the organisational chart current, especially in dynamic environments.
Solution: Assign responsibility for maintaining the organisational chart. Integrate updates into the change management process.

ISO 27001 Roles and Responsibilities Template
Document the Information Security Roles Assigned and Responsibilities and set out the roles and responsibilities with allocated resource.
ISO 27001 Management Review Template
Implement a Management Review Team with representatives from across the business and ensure meetings follow the structured Management Review Team Agenda.
ISO 27001 Competence Template
Document a Competency Matrix to capture the core competencies and training requirements of staff in relation to information security.
How to pass the ISO 27001 Clause 5.3 audit
To pass an audit of ISO 27001 Clause 5.3 Roles and Responsibilities you are going to
- Decide what roles you need
- Allocate roles to people
- Ensure people are competent to perform the role
- Implement a Management Review Team
- Document it
What an auditor looks for
The ISO 27001 certification body auditor is going to check a number of areas for compliance with ISO 27001 Clause 5.3 Organisational Roles, Responsibilities and Authorities. Lets go through them:
- That you have documented roles and responsibilities: This is the easiest one for them to check. They want to see that roles and responsibilities have been defined and allocated. The easiest way is to use the ISO 27001 Roles and Responsibilities Template. The main roles they want to see documented are the information security manager and the management review team.
- That people allocated are still in the organisation: This is an easy one for them as most people do not keep their documentation up to date and as a result there will be people documented as being allocated to roles that no longer work in the organisation. 3. That people are competent to perform the role
- It isn’t enough to document and allocate roles. The roles that are allocated need to be allocated to people that are competent to perform the role. This not a tick box and documentation exercise, it is about getting the management system operating effectively with people that are experienced and know what they are doing.
Common Mistakes and How to avoid them
In my experience, the top 3 mistakes people make for ISO 27001 Clause 5.3 Organisational Roles, Responsibilities and Authorities are:
| The Mistake | Why it Fails the Audit | The Auditor’s Solution |
|---|---|---|
| 1. Vague or Generic Job Titles Stating “The IT Department is responsible for security” instead of naming specific roles. | Auditors cannot establish accountability. If everyone is responsible, no one is responsible. It leads to critical security controls falling through the cracks. | Document explicit roles using an ISO 27001 RASCI Matrix. Assign a specific, named individual to be accountable for every single Annex A control. |
| 2. The Communication Black Hole Defining roles perfectly in a Word document, but failing to tell the rest of the business who they are. | The 2022 standard explicitly demands roles are communicated “within the organisation.” If I ask a random employee who the Information Security Manager is and they do not know, you will receive a non-conformity. | Broadcast your security organisational chart on the company intranet, include it in mandatory staff onboarding, and track digital policy acknowledgements. |
| 3. Authority vs. Responsibility Mismatch Making someone responsible for incident response, but failing to give them the system permissions or executive authority to actually execute it. | You have created a scapegoat, not a security leader. “Authorities” is literally in the clause title: you must prove the assigned role has the technical and administrative power to act. | Align documented job descriptions directly with your Identity and Access Management (IAM) system permissions and ensure the role has a direct reporting line to Top Management. |
Applicable Laws and Related Standards
As an ISO 27001 Lead Auditor, I frequently see organisations treat compliance as a siloed exercise. The reality is that implementing ISO 27001 Clause 5.3 (Organisational Roles, Responsibilities and Authorities) acts as the foundational governance layer for almost every major global cybersecurity and data privacy regulation. By clearly defining who is accountable for security, you simultaneously satisfy the governance requirements of frameworks ranging from NIST to the UK’s Cyber Security and Resilience Bill.
Below is the exhaustive mapping table detailing how ISO 27001 Clause 5.3 aligns with global laws and industry standards. You can use this to demonstrate cross-framework compliance to your stakeholders and external auditors.
| Standard / Legislation | Relevant Section / Principle | How it Maps to ISO 27001 Clause 5.3 |
|---|---|---|
| NIST CSF 2.0 | Govern (GV.RR-01, GV.RR-02) | Directly aligns with the requirement that organisational leadership is accountable for cybersecurity risk. It requires roles, responsibilities, and authorities to be formally established, communicated, and understood across the business. |
| NIS2 Directive (EU) | Article 20 (Governance) | NIS2 holds management bodies personally liable for non-compliance. Clause 5.3 provides the exact mechanism to satisfy this by mandating that Top Management assigns specific authorities for risk management and receives direct performance reports. |
| DORA (Digital Operational Resilience Act – EU) | Article 5 (Governance and Organisation) | DORA demands the management body defines, approves, and oversees the ICT risk management framework. Clause 5.3 fulfills this by establishing the reporting lines and delegating the daily operational authority to an Information Security Manager. |
| SOC 2 (Trust Services Criteria) | Control Environment (CC1.3) | SOC 2 requires management to establish structures, reporting lines, and appropriate authorities. Implementing Clause 5.3 provides the organisational chart, RACI matrices, and job descriptions required to pass this SOC 2 criterion. |
| UK Data (Use and Access) Act 2025 | Accountability Frameworks | While streamlining administrative burdens compared to legacy GDPR, this Act still demands demonstrable accountability. Clause 5.3 ensures that a designated individual holds the authority for data security compliance and reporting breaches. |
| Cyber Security and Resilience Bill (UK) | Mandatory Reporting & Governance | To meet the strict mandatory reporting timelines for critical infrastructure and Managed Service Providers (MSPs), organisations must use Clause 5.3 to authorise specific roles (e.g., Incident Commanders) to declare incidents to regulators without bureaucratic delays. |
| CIRCIA (USA) | Mandatory 72-Hour Reporting | The Cyber Incident Reporting for Critical Infrastructure Act requires rapid notification. Clause 5.3 ensures the authority to report is pre-delegated, preventing catastrophic delays while waiting for executive sign-off during a live crisis. |
| GDPR (EU & UK) / Data Protection Act 2018 | Article 24 (Responsibility of Controller), Articles 37-39 (DPO) | Clause 5.3 supports the formal designation of the Data Protection Officer (DPO) or privacy lead, ensuring they have the explicit authority, resources, and direct reporting line to the highest management level to protect personal data. |
| EU Product Liability Directive (PLD) Update | Software & Cyber Flaw Liability | With strict liability extending to software providers for cybersecurity flaws, Clause 5.3 ensures explicit ownership is assigned for secure coding practices, vulnerability management, and quality assurance testing prior to product release. |
| EU AI Act & ISO 42001 (AI Management) | Article 14 (Human Oversight), Clause 5.3 (ISO 42001) | Requires clear governance over AI systems. Clause 5.3 maps seamlessly by forcing businesses to assign named individuals the authority to monitor AI outputs, intervene in automated decisions, and report on AI risks to the board. |
| ECCF (European Cybersecurity Certification Framework) | Conformity Assessment Governance | Achieving harmonised EU security labels requires a robust internal governance structure. Clause 5.3 proves to external assessors that the organisation has assigned competent personnel to maintain product security baselines continuously. |
| HIPAA (USA) | Security Rule: 45 CFR § 164.308(a)(2) | HIPAA explicitly demands an “Assigned Security Responsibility” to identify the official responsible for the development and implementation of security policies. This is a 1:1 match with the Information Security Manager role defined under Clause 5.3. |
| California Data Laws (CCPA / CPRA) | Reasonable Security Procedures | To maintain “reasonable” security and process consumer data requests legally, Clause 5.3 ensures roles are assigned for data mapping, privacy rights execution, and safeguarding consumer records against unauthorised access. |
Applicability across different business models
| Business Type | Applicability | Why it is Important | Clause 5.3 Roles & Responsibilities Examples |
|---|---|---|---|
| Small Businesses | Critical / Direct | In small teams, “wearing multiple hats” causes confusion. Documenting roles prevents critical security tasks (like backups or patching) from being ignored because everyone assumed “someone else” was doing it. | The Business Owner explicitly assigning the “Information Security Manager” responsibility to the Operations Manager to ensure one person is accountable for the ISMS. |
| Tech Startups | Strategic / Scalable | Rapid growth breaks informal processes. Investors require clear governance structures to prove the company isn’t reliant on a single “hero” developer for security. | Defining the CTO’s authority to approve security policies vs. the Lead Developer’s responsibility to implement secure coding practices, ensuring a clear Segregation of Duties. |
| AI Companies | Governance / Mandatory | With high-risk data models, accountability is often a regulatory requirement (e.g., EU AI Act). You must define who is liable for data ethics and model integrity. | Assigning a dedicated “AI Data Governance Lead” with the authority to halt model training if privacy protocols are breached, reporting directly to Top Management. |
ISO 27001 Clause 5.3 FAQ
What are the ISO 27001:2022 Changes to Clause 5.3?
The changes to ISO 27001 clause 5.3 for the 2022 update are minor at best. Changing the word ‘International Standard’ to the word ‘document’ and adding clarification that communication is within the organisation as was always implied but never said out right. Nothing material.
What is the main purpose of Clause 5.3?
The main purpose is to prevent ambiguity and ensure accountability. By clearly defining who is responsible for what, an organisation can ensure that all necessary information security tasks are carried out, risks are managed, and the ISMS is maintained effectively. It’s the foundation for a well-governed ISMS.
What’s the difference between “roles,” “responsibilities,” and “authorities”?
It is vital to distinguish between these three terms to create a clear governance structure:
- Roles are the functions or positions within the organisation (e.g., IT Manager, Chief Information Security Officer).
- Responsibilities are the specific duties or tasks associated with a role (e.g., conducting risk assessments, managing access controls).
- Authorities are the permissions or decision-making power granted to a role to carry out their responsibilities (e.g., the authority to approve a new security policy or allocate budget for security tools).
Can one person hold more than one role?
Yes, absolutely. ISO 27001 is flexible. One person can hold multiple roles, especially in smaller organisations where resources are limited. The key is to ensure that the roles and responsibilities are clearly defined and that there are no conflicting duties. For example, the same person shouldn’t be responsible for both implementing a security control and independently auditing it.
Who is responsible for ISO 27001 Roles and Responsibilities?
Top management is ultimately responsible for ensuring Clause 5.3 is implemented. This demonstrates their commitment and leadership in information security. While they don’t have to perform every task themselves, they must assign the responsibilities and authorities to the appropriate people or teams within the organisation.
What specific responsibilities must be assigned?
Clause 5.3 requires two key responsibilities to be assigned:
- Ensuring the ISMS conforms to the ISO 27001 standard.
- Reporting on the performance of the ISMS to top management.
These two roles are critical for the successful implementation and continuous improvement of the ISMS.
How often are roles and responsibilities reviewed?
After any significant change to the organisation, any significant change to personnel and at least annually.
How do we prove compliance with Clause 5.3 during an audit?
An auditor will look for documented evidence that:
- Roles and responsibilities for the ISMS are clearly defined.
- These roles have been assigned to specific individuals or teams.
- The assignments have been formally communicated and are understood by employees.
- The individuals assigned to these roles are competent to perform their duties. They may do this through interviews and reviewing your documentation.
How do you monitor the effectiveness of ISO 27001 Clause 5.3 Roles and Responsibilities?
The approaches to monitoring the effectives of the ISO 27001 Clause 5.3 include:
- Internal audit of the documented roles and responsibilities
- External audit of the documented roles and responsibilities
- Review of anomalies in operation of the information security management system (ISMS)
Does Clause 5.3 require new job titles or hiring new staff?
No, it does not. The standard doesn’t require specific job titles like “CISO” or “Information Security Manager.” It requires that the responsibilities are assigned. These can be given to existing employees as an additional part of their current role, such as a CEO, IT manager, or department head.
How should these roles and responsibilities be documented?
They should be documented in a way that is clear and easily accessible to all relevant parties. Common documentation methods include:
- An organisational chart.
- Job descriptions.
- A Responsibility Assignment Matrix (like a RACI chart).
- The Information Security Policy or other formal procedures.
What happens if we don’t define and communicate these roles?
Without a clear framework, security responsibilities can fall through the cracks, leading to:
- Gaps in controls: No one is assigned to manage specific security measures.
- Ineffective incident response: Confusion about who should handle a security breach.
- Audit non-conformance: Auditors will identify the lack of a clear governance structure as a major issue, potentially leading to a failed certification.
