Which of the following describes a potential security measure for FSL I facilities?

A potential security measure for FSL I facilities that stands out is the implementation of simple physical barriers to impede unauthorized activity. Physical barriers, such as fences, gates, and walls, serve as a fundamental layer of security by creating a deterrent that makes it more difficult for unauthorized individuals to access restricted areas. These barriers can be effective in controlling and monitoring access points and are often a necessary first step in any security strategy, particularly in facilities that require a baseline level of protection.

In the context of security measures, simple physical barriers are easily maintainable and can be quickly implemented, making them a practical choice for protecting sensitive infrastructure. They provide a tangible and visible presence that informs potential intruders that access is restricted, enhancing the overall security posture of the facility.

Other options, while they may represent advanced security measures, tend to focus on technology or intelligence-gathering aspects that might not be as immediately actionable or suitable for all facility types. In some cases, a solid physical barrier can be more effective than technical solutions, especially in environments where immediate access control is necessary.
