Traditionally the connotation of the word "security" has been "insecurity," focusing generally on criminals and crime. However, security concerns itself more than with the effective deterrence of criminal acts, and a security system built simply on deterrence cannot be successful. Security involves more than planning for and developing a system whereby perpetrators of criminal acts are apprehended. Successful security systems plan and develop strategies which address both the individual's right to be free from criminal victimization and his or her psychological need to feel secure.
