Many physical security measures must be implemented by your organization, such as the choice of access control, alarms and surveillance.

 

Here is some advice on what you can each do – and guidelines for the overall work concerning physical security.

 

First, some advice for the individual employee:

 

Access

  • Protect your access code so others cannot see it.
  • Keep your access card visible when you are inside the perimeter. This reduces the risk of tailgating – i.e. an intruder gaining unauthorized access by following someone with an access card. 
  • Put away your access card when it is not relevant, for instance when going to and from work.

Building and rooms

  • Be aware of visible vulnerabilities such as open windows on the ground floor.
  • Be aware of the details in your physical surroundings. Are there any indications of attempted forced entry?
  • Be aware of compromised physical security measures such as security doors that have been wedged open.
  • Prevent people from looking in. Set up your workstation so that screens, whiteboards etc. face away from windows and other areas where there is a risk of people looking in. Alternatively, use curtains/blinds as required. 
  • Use rooms as intended. For example, do not take a sensitive discussion from the conference room to the kitchen.
  • Observe your closing procedure. For example, make sure that all windows, doors and safes are closed when you leave the room.

Storage and handling

  • Observe your procedure for secure storage of documents etc. If you have a safe with a code, make sure others do not see the code.
  • Observe your procedure for secure disposal of documents etc. Use a shredder, for instance.
