What is the purpose of physical control barriers?

• A. To Deny, Impede, Delay, and Discourage Access to Restricted and Non-Restricted Areas by Unauthorized Persons.
• B. To Speed Up Entry for Authorized Personnel
• C. To Reduce Expenditure on Security
• D. To Create a Welcoming Entry

Answer: (A)

The purpose of physical control barriers is to deny, impede, delay, and discourage access by unauthorized persons to both restricted and non-restricted areas. These barriers create a tangible line of defense that requires proper verification or credentials before entry, making it harder for someone to wander into secured spaces or past sensitive zones. They send a clear signal that access is controlled, which helps deter attempts and increases the chance that any unauthorized activity will be detected. While barriers might occasionally streamline entry for those with authorization or contribute to the overall look of a site, their primary role is enforcing access control and reducing security risk, not speeding up entry, cutting costs, or creating a welcoming reception.
