Check controls

How often should the security controls be check-listed?
 

Answer:

You can check your list of controls as many times as you like in 1 year, but as a minimal you can check this list once a year in the Internal Audit. To perform this check, you can use the Statement of Applicability, because it contains the applicability of all controls.
