1. A deception management system (DMS) to detect attackers within a dynamically changing network of computer resources, comprising: a deployment governor dynamically designating deception policies, each deception policy comprising one or more decoy attack vectors, one or more computer resources of the network in which the one or more decoy attack vectors are generated, and a schedule for generating the one or more decoy attack vectors in the one or more resources, wherein an attack vector is an object in a first resource of the network that has a potential to be used by an attacker to access or discover a second resource of the network, and wherein the network of resources is dynamically changing; a deception adaptor dynamically extracting characteristics of the network; a deception diversifier dynamically triggering changes in the deception policy based on changes in the network as detected from the network characteristics extracted by said deception adaptor, and enabling an administrator of the network to set levels of deception diversity across resources in the network; and a deception deployer dynamically generating one or more decoy attack vectors in the one or more resources in the network, in accordance with the current deception policy and in accordance with the levels of diversity set by the administrator.
