Investigative security involves compilation of facts, used to identify, trace and provide prove of a criminal offense. A complete investigation consists of searching, interrogations, facts collection and protection in addition to other investigation techniques. Planning and prudence are crucial to successful resource management. Investigators should identify the resource requirements of an investigation at the most primitive opportunity. When making decision on the resources needed, the investigator should consider the suitable level of investigative response, the accessibility and cost of the necessary resources and whether their use is balanced. Some of the investigations carried out in this area include, financial felonies, money laundering, commercial scam and intellectual property burglary, cybercrimes, civil rights violations and human trafficking.
