Secure process by design should be secure if operated according to prescribed scenarios.
Passenger screening for human and hand-carried items before entering the departure zone deploys multiple means:
- Administrative: limited quantity of fluid and no sharp objects,
- Technical enforcement: human and bags scanning to detect violation
If everything goes into departure zone thru this process, then exception can be picked up and assure the policy mandate.
But what about supplies to the shops inside the zone? Do these go thru similar process? If not, it’s backdoor and a broken process.
