I sincerely hope this is not the case in your outfit SoS, such procedures may be well known within the industry but they are still 'restricted' within my company. No airline worthy of respect would needlessly compromise it's own security procedures on the basis of a phone call or letter.
And anyway, that's no reason to hand the information out on a plate; as I said before, most robust procedures account for the fact that their 'restricted' nature has been compromised, but we still need to keep such information as secure as we can and at least attempt to maintain the upper hand.
