PTP Approach In Network Security for Misbehaviour Detection

A PTP Approach in Network Security for Misbehaviour Detection system presents a method for detecting malicious misbehaviour activity within networks. Along with the detection, it also blocks the malicious system within the network and adds it to Blacklist. Malicious node is defined as a compromised machine within the network that performs the task provided by i.e. it does not forward the legitimate message to another node in the network or sends some other message to a neighbour node. This system is based on Probabilistic threat propagation. This scheme is used in graph analysis for community detection. The proposed system enhances the prior community detection work by propagating threat probabilities across graph nodes. To demonstrate Probabilistic Threat Propagation (PTP) considers the task of detecting malicious node in the network. Proposed System also shows the relationship between PTP and loopy belief propagation.
