Security Concepts
What the exam tests
This domain checks whether you can use basic security vocabulary precisely. RBSE Sec Voc Security questions often ask you to separate a threat from a vulnerability, and risk from danger, and to explain why security is built in layers rather than as a single guard or gadget.
Core rules
- Asset: anything worth protecting - people, property, information, reputation.
- Threat: a person or event with the potential to cause harm. Vulnerability: a weakness that lets the threat succeed. Risk: the likelihood and impact of loss when threat meets vulnerability.
- Security protects against deliberate human action; safety protects against accidental harm. The two overlap in fire and emergency work.
- Layered security uses deterrence, detection, delay and response. A fence deters, CCTV detects, a locked door delays, and a guard responds.
- Loss prevention aims to stop loss before it happens, not only to catch offenders afterwards.
Worked example
A store has one unlocked rear door, no lighting and a guard at the front. The threat is burglary; the vulnerabilities are the unlocked door and darkness; the risk is high because entry is easy and the guard cannot see the rear. The fix is not simply “hire another guard”. Lock and alarm the rear door, add lighting and a camera, and give the guard a patrol check. That is layered control.
Traps that cost marks
Do not write “risk” when the question asks for “threat”. Do not claim security means only guarding. Do not treat CCTV as prevention by itself; it usually detects and records. Do not ignore information and people when listing assets.
Exam tip
When a scenario names a weakness, label it as a vulnerability, then state the control that removes or reduces it.
