Give them the assignment of figuring out how to put them back together while avoiding casual detection. "<br /><br />Unfortunately, seals that have been intentionally "permanently" broken, such as they are in normal use, are generally rather difficult to reassemble. They're designed that way, and when used that way, they work rather well.<br /><br />*Covert* tampering is the threat we've discussed in our recent research, and detection of it requires a higher scrutiny during inspection than is currently required by any standard.<br /> <br />For most of the common seals we covered in our paper, including the bolt locks, cup seals, and plastic-covered shatter bolts commonly used in shipping hazardous materials and sensitive chemicals, covert tampering requires altering the device before inspection so that the primary breakage-identification mechanism remains intact -- that is, the "seal" part of the seal remains sealed, visibly and with most physical tests (tugging, jarring the seal). A normal broken (sheared) container bolt won't be able to be reassembled without evidence, but a modified bolt that has been carefully sliced off from the wrong end, drilled out and reassembled (again at the wrong end), would pass all too easily.<br /><br />The good news is that your security team *can* be trained to identify most covertly modified devices, and i11 can offer this training.Jamie Schwettmannhttp://www.i11industries.comnoreply@blogger.com
