This article provides additional information on how you can meet the requirement for the ISO 27001: 2022 control A.5.2 Information security roles and responsibilities
ISO 27001: 2022 Control Description
Information security roles and responsibilities shall be defined and allocated according to the organisation needs.
Purpose
To establish a well-defined, approved, and comprehensible structure for the implementation, operation, and management of information security within the organisation.
Guidance on Implementation
The organisation should define and manage responsibilities for:
a) Protection of information and related assets
b) Execution of specific information security processes
c) Information security risk management activities, including the acceptance of residual risks (e.g., by risk owners)
d) All personnel using the organisation’s information and related assets
These responsibilities should be supplemented with detailed guidance for specific sites and information processing facilities when necessary. Individuals with assigned information security responsibilities can delegate tasks to others but remain accountable and must ensure that delegated tasks are performed correctly.
Each security area assigned to individuals should be clearly defined, documented, and communicated. Authorisation levels should also be defined and documented. Individuals assigned to specific information security roles should possess the necessary knowledge and skills and should be supported in staying current with developments related to their roles.
Additional Information
Many organisations appoint an information security manager to oversee the development and implementation of information security and to assist in identifying risks and implementing mitigating controls. However, individual managers often remain responsible for resourcing and implementing the controls. A common practice is to appoint an owner for each asset, who then becomes responsible for its day-to-day protection.
Depending on the organisation’s size and resources, information security may be managed by dedicated roles or as part of existing roles.
