An internal auditor is reviewing physical and environmental controls for an IT organization.

Physical and environmental controls protect IT assets from physical damage, unauthorized physical access, environmental hazards, and operational disruption. Fire detection and suppression, restricted access to tangible IT resources, and disaster recovery planning are relevant to this review. However, ensuring that a developer has access to both systems and operations is inappropriate because it violates segregation of duties. Developers should generally not have unrestricted operational access because they could introduce unauthorized changes, bypass testing, or manipulate production systems. Internal audit should identify excessive access as a control weakness, not a required control activity. Physical and environmental control reviews should include access badges, visitor logs, server room controls, power supply, fire protection, humidity control, and disaster recovery readiness. Therefore, Option D should not be part of the review.
