Mission briefing
This lesson is about running an access point: a gate, a door or a reception desk where people show that they may come in. Access control is often the first line of defence on a site. Part 2 continues with surveillance systems.
Focus: check every person, every time; keep a record; and know what to do when the system fails.
Learning objectives
By the end of this lesson, you will be able to:
- Explain what access control does and why it matters.
- Name the common ways people prove they may enter.
- Run an access point safely and fairly on every shift.
- Act correctly when an access system fails, and respect people's privacy.
1. What access control does
Access control decides who may enter a place, or reach certain information. It lets in only the people who are allowed. This cuts the risk of theft, damage and harm. It also keeps a record of who came in, and when.
2. How people prove they may enter
- Passes and ID cards — you check that the photo matches the face.
- Keypads — the person types a PIN (a secret number).
- Card readers — the person holds an RFID card near a reader. RFID means the card is read by radio waves.
- Biometric scanners — a fingerprint, eye (iris) or face scan.
- Phone passes — an app or a code on a mobile phone works like a card.
Doors, gates, locks, card readers and turnstiles are physical access control. Passwords and logins protect computers and data; they are digital access control. Guards mostly run the physical side.
Access levels. A card usually opens only the doors that the person's job needs. A cleaner's card may open offices but not the server room. If someone asks you to let them through a door their card does not open, check with your supervisor first.
3. Running the access point
Checking a pass properly. Ask the person to hand you the pass, or hold it up close. Look at:
- the photo — does it match the face in front of you?
- the name and, if shown, the company or department;
- the dates — is it still valid today?
- the area — does it allow entry to this place, at this time?
- the card itself — is it damaged, changed or a photocopy?
If anything is wrong, do not let the person in yet. Stay polite: "Sorry, I cannot accept this pass. Please wait while I check with my supervisor." Do not accuse anyone. Many problems are honest mistakes.
On every shift:
- Check everyone the same way. Look at the pass and the face, every time, even for people you know.
- One person, one card. Watch for tailgating: someone walking in close behind another person without using their own card. Stop them politely and ask for their pass.
- Never lend or share cards, codes or keys.
- Lost card? Report it at once, so it can be blocked. A lost card in the wrong hands is an open door.
- Doors propped open defeat the system. Close them and report it.
- Log anything unusual, and report faults in readers, locks and turnstiles.
Access control works best when it is joined up with cameras and alarms, so the whole site works as one system. For visitors, contractors, couriers and gate passes, see unit 10A, Gate, Visitor and Material Control. For keys, locks and safes, see unit 10B, Keys, Locks and Safes on Your Post. For gate and car-park traffic, see unit 10C, Parking and Traffic Duty.
4. When the system fails
Readers, locks and software can fail. Know your post orders for each case.
- Fail open means the system lets people through without a full check when it fails. Unit 9A (Exits, Escape Doors and Electric Locks) calls a lock that opens on failure fail-safe: people can still get out, but entry is no longer checked. This is a security risk, so look at every pass and face yourself until it is fixed.
- Fail secure means entry stays locked.
Whatever fails, escape doors must always let people out. Only entry should stay locked. See unit 9A, Exits, Escape Doors and Electric Locks.
5. Privacy and fairness
- Personal data. Fingerprints and face scans are personal data. They must be collected, stored and used lawfully and safely. Do not share them.
- Fair to everyone. People with a disability must be able to use the system, or be given another fair way in.
Activity — analyse a case
Case study: a failure at a data centre.
A data centre used two checks at its door: an RFID card and a fingerprint scan. A software update switched off the fingerprint check by mistake. The system "failed open": a card alone now let people in. An intruder used a copy of a lost card. Nobody noticed for two days.
Remember: whatever fails, escape doors must always let people out. Only entry should stay locked when a system fails. Unit 9A, Exits, Escape Doors and Electric Locks, explains this.
Think about these questions:
- Why was a card alone not enough after the update?
- What should the guards have done while the fingerprint check was not working?
- Which simple habits (reporting lost cards, checking the door log) would have caught this sooner?
There is no single right answer. The goal is to link this lesson to a real failure.
Conclusion
You have completed this lesson. You now know:
- What access control does and why it is a first line of defence.
- How people prove they may enter, and how access levels work.
- How to run an access point, and what to do when the system fails.
- Why privacy and fairness matter.
The next units cover visitors and material, keys and safes, and parking and traffic. Then Part 2 looks at surveillance systems.
