Information Security Roles and Responsibilities in ISO 27001

ISO 27001 is the international standard for information security management systems (ISMS). A key aspect of implementing ISO 27001 is clearly defining roles and responsibilities related to information security and the management system. This ensures that all aspects of the ISMS are properly managed and that there’s accountability throughout the organisation.

There are some common roles which should be considered in every organisation considering obtaining ISO27001 Certification and they are:

1. Top Management – This could be Board Directors, Senior Management Team etc
– Demonstrate leadership and commitment to the ISMS
– Establish the information security policy and objectives
– Ensure integration of ISMS requirements into organisational processes
– Provide necessary resources for the ISMS
– Communicate the importance of effective information security management

2. Project Lead – This could be a director, Head of IT or other senior leader

– Oversee the implementation and operation of the ISMS
– Report on ISMS performance to top management
– Coordinate internal audits and management reviews
– Manage information security risks

– Respond to security incidents and implement lessons learned
– Ensure compliance with ISO 27001 requirements

3. Asset Ownership – this may fall to the IT team or HR – it’s all about asset ownership
– Identify and maintain an inventory of information assets (devices etc)
– Determine acceptable use of assets
– Ensure appropriate protection of assets
– Review and update access rights regularly

4. Human Resources
– Conduct background checks on potential employees

Clearly defining these roles and responsibilities helps organisations:

Remember, while specific individuals may be assigned to these roles, information security is ultimately everyone’s responsibility in an organisation implementing ISO 27001.
