Fly in and out of CAI fairly regularly and worth noting the security there actually has two levels. You can't get through to the check in desks without first passing through an initial baggage x ray and body check. You also are not allowed to proceed without a valid boarding pass or booking checked against the manifest (fun for standby staff travel).
Security is then conducted at the entrance to the gate waiting room, this has always seemed as effective as other airports to me.
All of the above is irrelevant if the security threat is a person/persons with an airside pass and access to the a/c movement/parking/maintenance areas.
I suspect this is the focus of attention of the British "security experts" dispatched to SSH this evening.
