What is required of all barriers in a security context?

In a security context, barriers are primarily utilized to provide protection and control access to designated areas. The requirement for barriers to afford an equal degree of continuous protection is crucial because it ensures that there are no gaps in security that could be exploited. Continuous protection means that the barrier consistently deters unauthorized access, provides a safe environment, and effectively outlines secured zones.

Barrier effectiveness is not just about physical presence but also about reliability; if a barrier is easily movable or not imposing enough, it might be disabled or bypassed during attempts of unauthorized entry. While visual appeal and environmental friendliness are factors that can be considered in the design process, they do not fundamentally address the core function of a barrier, which is to protect against threats. Therefore, the emphasis on continuous protection highlights the primary objective of any security measure.
