What would be an indicator of effective perimeter security?

An indicator of effective perimeter security is fewer unauthorized access incidents. When a perimeter security system is functioning well, it should successfully prevent unauthorized individuals from entering the premises. This reflects the effectiveness of various security measures in place, such as fences, gates, surveillance cameras, and access control systems. A reduction in such incidents not only demonstrates that the physical barriers are effective but also suggests that the overall security strategy is successfully deterring potential intruders.

In contrast, increased vandalism would typically be seen as a sign of ineffective security, as it indicates that individuals can breach the perimeter and cause damage without being deterred. High employee turnover may signify other organizational issues but does not necessarily relate directly to the effectiveness of perimeter security. Regular maintenance of security equipment is essential for maintaining security systems, but it is the actual outcome of fewer unauthorized access incidents that serves as a more direct indicator of the security's success.
