An attacker uses techniques and methods to bypass physical security
						mesures of a building or facility. Physical locks may range from traditional
						lock and key mechanisms, cable locks used to secure laptops or servers,
						locks on server cases, or other such devices. Techniques such as lock
						bumping, lock forcing via snap guns, or lock picking can be employed to
						bypass those locks and gain access to the facilities or devices they
						protect, although stealth, evidence of tampering, and the integrity of the
						lock following an attack, are considerations that may determine the method
						employed. Physical locks are limited by the complexity of the locking
						mechanism. While some locks may offer protections such as shock resistant
						foam to prevent bumping or lock forcing methods, many commonly employed
						locks offer no such countermeasures.
