Physical Security Professional Certification Practice Exam 2025 – Comprehensive Prep Guide

Barriers and locks play integral roles in enhancing physical security by working in tandem to control access. Barriers such as fences, walls, or gates serve to physically restrict entry to a space, creating a first line of defense against unauthorized access. By creating a physical obstruction, barriers reduce the chances of an intruder gaining easy entry.

Locks complement these barriers by securing the access points, such as gates or doors, effectively preventing unauthorized access even when barriers are present. They add an additional layer of security by ensuring that, even if barriers are circumvented, access points remain controlled.

The collaboration between barriers and locks is essential in a comprehensive security strategy. Barriers without locks may dissuade entry but do not provide full security, as determined intruders might still find a way through or over them. Conversely, locks that are not part of a broader barrier strategy may not be sufficient to deter or prevent unauthorized entry if access points are easily bypassed. Thus, the correct understanding is that barriers restrict access while locks secure those access points, enhancing overall security measures.
