The receptionist left her post for two minutes. A delivery driver is standing by the front desk. A man in a contractor’s jacket walks in behind an employee. Nobody knows if this guy was supposed to be there. Nothing out of the ordinary happens. This is usually how trouble begins, not with an intrusion, but with a lapse in attention and a lack of knowledge about who crossed the threshold.
This is why an audit trail is important. It doesn’t matter if you’re in a school, a government building, a business, or a co-working space; knowing who came into your room, how long they were there, and how they got in isn’t paranoia. It is common sense. Access control systems are used to keep the right people out. But good systems also help everyone understand what happened afterwards.
Allowing Familiarity To Take The Place Of Verification
We all judge whether we let others in based on how we perceive their identity. We let them go based on what they are wearing. Some have lanyards, some have clipboards, some wear work boots. And they seem confident. Almost all of us make quick judgments of other people. Especially in a fast-paced environment with lots of distractions and staff doing ten things at once.
Familiarity is a poor security measure. A person may enter a record’s office, a server room or a meeting room without verifying their identity, but there might be no dependable method of tracking that visit later. An access control system removes our dependence on memory. Log entries, access cards, and visitor records provide much better information than guessing.
Viewing Entry As A Single ‘Front Door’ Issue
Most organisations have historically been focused on the ‘front door’ of the facility. However, the biggest problem usually lies internally. Who went into the Archives Room? Who looked at an employee’s file in HR?
Layering provides real security by recognising the difference between spaces in a building in terms of levels of risk. Not all employees require equal access to all areas. Security and access control must be adaptable, reflecting a building’s diverse areas and the unique oversight required for each one.
Forgetting That Records Also Protect Employees
Audit trails are commonly viewed as simply a tool for investigating. Audit trails can also protect employees, contractors, and visitors. For example, in the event of lost equipment or a safety incident, the access history for that area can stop the wrong employee from being accused.
This is more important than people realise. In multi-team environments where multiple groups share a facility, details get muddled quickly. One person remembers a person in a blue jacket. Another person thinks the door was already unlocked. A digital record is emotionless, non-selective, and provides much more usable information.
Implementing Systems Without Everyday Practice
Technology is helpful, but technology will only be effective if people use it correctly. A fire extinguisher propping open a secure door defeats the whole purpose. So does passing a single employee ID card back and forth among employees, because it is easier.
Access is often thought of as decision-making power. Who can enter? Who cannot? Whether anybody would even notice if the wrong person entered. If a room is important, then the entry record for that room is important.
