Which is an example of a Physical Control?

1. Access Control Lists

2. Firewalls

3. Locked Doors

4. Security Policies

The correct answer is: Locked Doors

A physical control refers to tangible measures taken to deny unauthorized access to facilities, equipment, or resources. Locked doors are a quintessential example of physical controls because they physically prevent individuals from entering secure areas. By securing access points with locks, organizations can ensure that only authorized personnel can access sensitive areas, thereby enhancing overall security. In contrast, access control lists and firewalls are examples of logical or technical controls, as they implement restrictions through software and network configurations rather than physical barriers. Security policies, while vital for guiding behavior and defining protocols, are documentation and guidelines rather than physical measures. Thus, locked doors stand out as a clear representation of a physical control within a security framework.
