A risk practitioner is reviewing accountability assignments for data risk in the risk register.

The risk owner is listed as the department responsible for decision making would pose the greatest concern for a risk practitioner who is reviewing accountability assignments for data risk in the risk register, as it indicates a lack of clarity and specificity on who is accountable for the risk and its response. The risk owner should be an individual, not a department, who has the authority and responsibility to manage the risk and its associated controls. The other options are not the greatest concern, as they do not necessarily imply a lack of accountability, but rather a possible difference in roles and responsibilities between the risk owner and the control owner, the business unit and the IT department, or the staff member and the department manager. References = CRISC Review Manual, 7th Edition, page 101.
