In addition, the security andprotective services may engage in follow up investigation ofintrusion investigation. This type is different as it focuses torespond to an intrusion or infringement of a situation such asnetworks or a protected compound.

Ofall the types of investigation done by the security agencies andprotective services, criminal investigation is the one that isconducted. In the community, many security and protective servicesengage in the process of investigating elements of a crime or relatedto crime. However, the state security agencies are the one who mostconduct this investigation. This is because crime is the most commonaspect of the society that calls for investigation and prevention inthe community.
