Quite possibly one of the least implemented
security features (I'd wager that even Body Cavity Search
es outdo it
), a duress code
is a simple extension to an access control system
. Many advanced access systems require that a user
enter in a PIN
code in addition to presenting a badge
. In such a system, a duress code is an alternate code
for that user, which signals to the system that the user is under coercion
. What the system does now depends on the configuration
, which is typically based on the sensitivity of the facility.
- High security facilities (like SCIFs), may immediately disable all access into the building, raise a visible alarm to inhibit egress, and notify the security forces, who will arrive with M-16s in a few minutes.
- Probably the poorest choice, this option would simply disable the access of the user under duress. Without forcing a facility-wide shutdown, another user could easily fall into the hands of the adversary, who may have nothing to lose by terminating their original victim.
- Silent alarm
- In a low security facility, this would raise an alarm with the security team, who would then investigate. All other access would be as if the user had entered their normal PIN.
