Question about GRC committee

First is important to note that 27001 does not regulate, not even mention a GRC committee. It only requires that relevant functions to information security are defined.

Considering that, the first steps would be for the committee to agree on what are the top-level objectives of information security, and what kind of role & authority the committee has so that it does not conflict with those of the security officer.

After that, as an information security officer, in case of objectives, are changed, and also considering the committee’s roles and authorities, you should evaluate if any changes are required in the ISMS. In case changes are required these need to be evaluated by management representatives to decide if they will be implemented or not. The following steps are similar to those related to ISMS implementation:

• update ISMS basic framework (e.g., scope, objectives, organizational structure), by understanding the organizational and requirements of interested parties

• update risk assessment and treatment methodology

• perform a risk assessment and define a risk treatment plan

• controls implementation (e.g., policies and procedures documentation, acquisitions, etc.)

• people training and awareness

• controls operation

• performance monitoring and measurement

• perform internal audit

• perform management critical review

• address nonconformities, corrective actions, and opportunities for improvement
