High Quality Content by WIKIPEDIA articles! Defense in depth is an information assurance (IA) strategy in which multiple layers of defense are placed throughout an information technology (IT) system. It addresses security vulnerabilities in personnel, technology and operations for the duration of the system's life cycle.The idea behind the defense in depth approach is to defend a system against any particular attack using several, varying methods. It is a layering tactic, conceived by the National Security Agency (NSA) as a comprehensive approach to information and electronic security.Defense in depth is originally a military strategy that seeks to delay, rather than prevent, the advance of an attacker by yielding space in order to buy time. The placement of protection mechanisms, procedures and policies is intended to increase the dependability of an IT system where multiple layers of defense prevent espionage and direct attacks against critical systems.
