Deterrence

The use of visible security measures such as guards, lighting, or barriers to discourage a potential offender from attempting an act, by making the attempt appear risky or difficult.

Related: Defense in Depth, Access Control
Defense in Depth

A layered approach in which several independent controls, such as a perimeter fence, a locked door, and a guard, must each be defeated before an asset is reached.

Related: Deterrence, Access Control
Confidentiality, Integrity, Availability (CIA)

The three core properties of protected information and assets: only authorised people can see it, it stays accurate and unaltered, and it remains usable when legitimate users need it.

Related: Need to Know, Chain of Custody
Risk Assessment

A structured process of identifying assets, threats, and vulnerabilities, then estimating the likelihood and impact of loss so that controls can be prioritised and justified.

Related: Vulnerability, Defense in Depth
Need to Know

The principle that a person receives only the information strictly required to perform their assigned duty, regardless of rank or seniority, limiting the damage from any single disclosure.

Related: Confidentiality, Integrity, Availability (CIA), Least Privilege
Least Privilege

Granting a person or system the minimum access rights and permissions needed for the task, and no more, so that misuse or error has limited consequences.

Related: Need to Know, Access Control
Access Control

Any procedure or device that decides who may enter a protected area, at what time, and under what conditions, and then enforces that decision at a controlled point.

Related: Least Privilege, Mantrap
Mantrap

A small enclosed space with two interlocking doors, arranged so that the second door cannot open until the first is fully closed, preventing tailgating into a secure area.

Related: Tailgating, Access Control
Tailgating

An unauthorised person following an authorised person through a door or gate without presenting their own credentials, often by exploiting courtesy or a crowded entrance.

Related: Mantrap, Challenge Procedure
Perimeter Barrier

A physical obstacle such as a wall, fence, or hedge that marks the outer boundary of a protected site and delays or channels anyone attempting unauthorised entry.

Related: Defense in Depth, Deterrence
Visitor Management

The controlled process of receiving outsiders: verifying identity, issuing a visible pass, recording entry and exit times, escorting where required, and recovering the pass on departure.

Related: Access Control, Log Book
Challenge Procedure

The scripted, polite steps a guard uses to question an unfamiliar person in a protected area, confirm identity and purpose, and escalate to a supervisor if satisfied answers are not given.

Related: Tailgating, Visitor Management
Post Orders

Written instructions for a specific guard position describing duties, patrol routes, permitted actions, reporting requirements, and the limits of the guard's authority at that post.

Related: Log Book, Use of Force
Log Book

A bound, chronological record in which guards enter events, patrols, visitors, and handovers, with time, date, and signature, so that activity can later be audited or reconstructed.

Related: Post Orders, Incident Report
Incident Report

A factual written account of an unusual event, recording who, what, when, where, and how, plus actions taken and witnesses, written promptly and without opinion or blame.

Related: Log Book, Chain of Custody
Chain of Custody

The unbroken documented record of who handled an item of evidence, when, and why, from seizure to final disposal, showing that it was not tampered with.

Related: Incident Report, Confidentiality, Integrity, Availability (CIA)
Fire Triangle

Related: Fire Class, Fire Extinguisher
Fire Class

A grouping of fires by the material burning, such as solids, flammable liquids, gases, and metals, used to select the correct extinguishing agent and method.

Related: Fire Triangle, Fire Extinguisher

A portable device that discharges a stored agent to suppress a small fire, selected by fire class and operated with the pull, aim, squeeze, sweep technique.

Related: Fire Class, Assembly Point
Assembly Point

A pre-designated safe outdoor location where occupants gather after evacuation so that a roll call can confirm everyone has left the building.

Related: Evacuation Drill, Fire Warden
Fire Warden

A trained person responsible for checking designated areas during an evacuation, guiding people to exits, and reporting to the assembly point whether the area is clear.

Related: Assembly Point, Evacuation Drill

A portable device that analyses heart rhythm and delivers a controlled shock when indicated, with spoken prompts guiding an untrained or minimally trained responder through its use.

Related: Cardiopulmonary Resuscitation (CPR), First Aid
Recovery Position

Related: Recovery Position, Automated External Defibrillator (AED)
Hazard Identification

The systematic spotting of conditions or actions with potential to cause harm, done by inspection, observation, and worker reports before an accident occurs.

Related: Risk Assessment, Hierarchy of Controls
Hierarchy of Controls

The ranking of risk-reduction measures from most to least reliable: eliminate the hazard, substitute it, engineer it out, change administrative procedures, and finally rely on personal protective equipment.

Related: Hazard Identification, Personal Protective Equipment (PPE)
