Target hardening, also referred to simply as hardening when made clear by the context, is a term used by police officers, those working in security, and the military referring to the strengthening of the security of a building or installation in order to protect it in the event of attack or reduce the risk of theft.
[3] In terms of business and home security, target hardening[4] is one of the suite of protective measures that are included in crime prevention through environmental design.
[5] This can include ensuring all doors and windows are sourced and fitted in such a way that they can resist forcible and surreptitious intruder attack, adding hard barriers and landscapes that resist vehicle and pedestrian intrusion, adding fences, walls and hostile planting.
[6] All of these are greatly assisted by removing or pruning any trees or bushes that could offer suitable hiding places or could be used to climb to a higher level of the property.
[7] In military or counter-terrorism terms, target hardening refers to ensuring strategic or tactical assets are secured against adversary attack.
