Annex A 5.2 verified ISO/IEC 27001:2022
Defining Information Security Roles and Responsibilities
Clearly assign security roles and duties to ensure nothing is overlooked.
record_voice_over
Plain language
Imagine if everyone in an organisation thought someone else was handling security, but no one actually did. This control is like a clear job list, so everyone knows who is responsible for keeping information safe. Without it, tasks can be forgotten, leaving valuable information exposed to risks and causing potential chaos.

Why it matters
If roles and responsibilities are not defined, security tasks are missed, accountability is unclear, and incidents may go unmanaged, increasing breach likelihood and reputational damage.

Operational notes
Maintain a RACI/role matrix; update it on staff or structure changes, and review quarterly to confirm owners for key security tasks and approvals remain current.

Implementation tips
- The IT manager should define specific roles for information security. They can start by reviewing the organisation's information security policy and identifying areas that need protection, such as customer data and internal processes. Then, clearly document who will be responsible for each area and ensure they have the necessary training and resources.
- HR should integrate information security responsibilities into job descriptions. By doing so, current and future employees will understand their roles in keeping information secure. This can be achieved by updating job roles with security responsibilities and setting expectations during onboarding.
- Senior management should assign an overall information security manager who oversees security implementations and risks. This person's role should be to coordinate security efforts across different departments, ensuring everyone knows their part in the organisation's security strategy.
- Department heads should ensure that specific security duties are allocated within their teams. They can do this by discussing security in team meetings and assigning tasks to team members who are both willing and capable. Regular updates and check-ins can help keep these responsibilities on track.
- The board should regularly review and approve the allocation of security roles and responsibilities. This ensures alignment with business needs and compliance with guidelines such as the Privacy Act 1988 and APRA CPS 234. Regular meetings can facilitate updates on the effectiveness of these roles.
