SIA Guard Access Control — Questions and Answers
Question 1: What is the primary purpose of access control in a security context?
- To make entry as difficult as possible for everyone
- To ensure that only authorised persons can enter specific areas while preventing unauthorised access (Correct answer)
- To count the number of people in a building
- To provide directions to visitors
Correct answer: To ensure that only authorised persons can enter specific areas while preventing unauthorised access
Access control manages who can enter specific areas, ensuring only authorised personnel gain access while preventing unauthorised entry. It is a fundamental principle of physical security.
Question 2: What is 'tailgating' in access control?
- Following a vehicle too closely
- When an unauthorised person follows an authorised person through a secure entry point without presenting their own credentials (Correct answer)
- A type of social event
- Parking too close to the building entrance
Correct answer: When an unauthorised person follows an authorised person through a secure entry point without presenting their own credentials
Tailgating (or 'piggybacking') occurs when an unauthorised person follows closely behind an authorised person through a controlled entry point, bypassing the access control system.
Question 3: What information should a visitor log or register typically contain?
- Only the visitor's name
- Name, company, person visiting, arrival time, departure time, car registration, and badge number issued (Correct answer)
- Just a signature
- Only the time of arrival
Correct answer: Name, company, person visiting, arrival time, departure time, car registration, and badge number issued
A comprehensive visitor log records: full name, company/organisation, person being visited, purpose of visit, arrival and departure times, vehicle registration, identification shown, and any visitor pass/badge number issued.
Question 4: What should a security guard do if someone claims to have forgotten their access pass?
- Let them in if they look like they belong there
- Follow the site's procedure for verifying identity — which may include contacting the person they claim to work with, checking photo ID, and issuing a temporary pass (Correct answer)
- Refuse entry completely with no alternative
- Ask them to describe their office
Correct answer: Follow the site's procedure for verifying identity — which may include contacting the person they claim to work with, checking photo ID, and issuing a temporary pass
The guard should follow the site's specific procedure, which typically involves verifying the person's identity through alternative means (photo ID, calling their manager/contact), and issuing a temporary pass if identity is confirmed.
Question 5: What is a 'mantrap' or 'airlock' entry system?
- A trap for catching intruders
- A two-door entry system where the first door must close before the second will open, preventing tailgating (Correct answer)
- A ventilation system for cleanrooms
- An emergency exit mechanism
Correct answer: A two-door entry system where the first door must close before the second will open, preventing tailgating
A mantrap (or airlock) uses two interlocking doors — the first must close completely before the second will open. Only one person can enter the space between doors, effectively preventing tailgating.
Question 6: Why is it important to issue and manage visitor passes or badges?
- To make visitors feel welcome
- To easily identify who is a visitor, ensure they are accounted for, and control their access to appropriate areas (Correct answer)
- To collect personal data
- To advertise the security company
Correct answer: To easily identify who is a visitor, ensure they are accounted for, and control their access to appropriate areas
Visitor passes serve multiple security purposes: they identify the wearer as a visitor (not staff), indicate which areas they may access, show if they should be escorted, and help ensure all visitors have signed out when they leave.
