NOT listed as one of the five publics served by security?

• A. Employees
• B. Visitors
• C. Emergency Personnel
• D. Customers

Answer: (D)

Understanding who security serves focuses on the groups that interact with the facility in everyday operations and during emergencies. In typical security practice, the publics recognized are those who are part of the daily environment and require access control, safety oversight, and coordinated response—such as staff, people visiting the site, and other service or response groups like vendors or contractors and emergency responders. These groups are the core focus because security plans, procedures, and communications are built around managing their access, movements, and safety.

Customers, while they are important to the overall business and can be affected by security measures, are not usually categorized as one of the five publics in standard security frameworks. They’re external to the security program’s day-to-day interface and access-control scope, which is why they aren’t listed among the five publics.
