Which of the following should be the IS auditor's PRIMARY focus when evaluating an organization's offsite storage facility?

Physical and environmental controls, such as access restrictions, fire suppression systems, temperature/humidity monitoring, and power backup, directly ensure the security, integrity, and availability of the data and hardware stored at the offsite location. Without these fundamental protections, the facility cannot reliably fulfill its purpose of secure and resilient data storage.

While business continuity plan (BCP) test results are important, they assess the plan's effectiveness, not the fundamental physical and environmental security of the offsite facility itself.
