The IDS under development is a collection of mobile agents that detect, classify, and correlate system and network activities. Software Fault Trees (SFTs), augmented with nodes that describe trust, temporal, and contextual relationships, are used to describe intrusions. CPNs for intrusion detection are built using CPN templates created from the augmented SFTs. Hierarchical CPNs are created to detect critical stages of intrusions. The agent-based implementation of the IDS is then constructed from the CPNs. Examples of intrusions and descriptions of the prototype implementation are used to demonstrate how the CPN approach has been used in development of the IDS.
