ABSTRACT:
The present invention relates to a method for containing propagation of a malware in a communication network having a plurality of communication nodes. The method steps include obtaining communication statistics from a traffic trace of the communication network, generating a weighted graph from the communication statistics to represent a communication pattern in the communication network, partitioning the weighted graph based on a pre-determined criteria into at least a first sub-graph representing a first portion of the communication network and a second sub-graph representing a second portion of the communication network, identifying a separator vertex from a plurality of vertices of the weighted graph, the separator vertex connecting the first sub-graph and the second sub-graph, the separator vertex representing a separator node of the plurality of communication nodes, and providing a security patch to the separator node for preventing propagation of the malware between the first portion of the communication network and the second portion of the communication network.
