The primary accountability for a control owner is to ensure the control operates effectively, as they have the authority and responsibility to design, implement, monitor, and report on the performance and adequacy of the control, and to identify and address any control gaps or deficiencies. Communicating risk to senior management, owning the associated risk the control is mitigating, and identifying and assessing control weaknesses are not the primaryaccountabilities, as they are more related to the roles and responsibilities of the risk owner, the risk practitioner, or the auditor, respectively, rather than the control owner. References = CRISC Review Manual, 7th Edition, page 101.
