Traditional methods for evaluating network security neglect the correlation of network vulnerabilities. To solve this problem, a method based on Colored Petri Net (CPN) modeling is presented. Potential attack sequences are built according to the correlation of network vulnerabilities. The weakness and key paths can be found through analyzing the attack sequences. Simulation results show that the proposed...
We introduce a social network analysis method as a new approach to build an Intrusion Detection System (SN-IDS) in ad hoc networks. The SN-IDS utilizes social relations as metrics-of-interest for anomaly detections, which is different from most traditional IDS approaches. To construct proper social networks, we first investigate ad hoc MAC and network layer data attributes and select relevant social...
