In this Powerpoint presentation, the LANL Team discusses new approaches regarding tamper intrusion and detection. Definitions are presented, including:
tamper detection: delayed (after the fact) detection of unauthorized access.
intrusion detection: immediate (real-time) detection of unauthorized access.
lock: a device to delay, complicate, and/or discourage unauthorized entry.
seal : a tamper-indicating device (TID) designed to leave non-erasable, unambiguous evidence of unauthorized entry or tampering. Unlike locks, seals are not necessarily meant to resist access, just record that it took place.
tag: a device or intrinsic feature (“fingerprint”) for uniquely identifying an object or container.
defeating a seal: opening a seal, then resealing (using the original seal or a counterfeit) without being detected.
attacking a seal: undertaking a sequence of actions designed to defeat it.
