Physical Security Planning and Deployment of Guards
From assessment to post orders
Planning begins with a site risk assessment: assets, threats, vulnerabilities and consequences, then layers of protection (perimeter, building envelope, interior, asset). The supervisor converts the assessment into a deployment plan - number and location of posts, fixed versus patrol, shift patterns, relief and response arrangements - and into post orders that state exactly what the guard does, what is prohibited, and whom to call. Understand defence in depth and crime prevention through environmental design basics: natural surveillance, sightlines, lighting, and eliminating concealment. Patrols should be routed and timed to avoid predictability; randomisation is a control, not a nicety.
Traps to watch
- Warm-body staffing: filling a post with any available guard ignores fitness, training and licensing for that post.
- Single point of failure: one gate, one key holder, one radio channel.
- Post orders that contradict site reality (e.g., instructing a guard to patrol an unsafe area alone at night).
- Confusing presence with protection: a visible guard without task definition is deterrence only, not control.
Rule of thumb
Assess, layer, document, rehearse. If a post cannot be described in writing with tasks, limits and escalation contacts, it is not yet planned.
Worked example
A warehouse loses stock from a loading dock. Rather than adding a guard at the front gate, the correct planning answer is to analyse the loss point (dock), then layer controls: access restriction at the dock, procedural checks on outbound loads, lighting and sightlines, and a randomised patrol timed to shift changes.
