Detecting Critical Link and Critical Node Vulnerability for Network Vulnerability Assessment

Savita R. Dhurde, Prof .A.Deshpande

The vulnerability assessment is the pro-active step to secure network organization. The network vulnerability is very important in today’s world for critical link and for critical node. The CLD (critical link disruptor) & CND (critical node disruptor) are always NP complete on the unit disk graph and power law graph and for the general graph we are analyze the CLD & CND. Finding the solution for CLD & CND problem by using HILPR algorithm, HILPR algorithm is linear programming algorithm. . In this paper we are proposed one of the novel methods is belief propagation used for critical link and critical node vulnerability for network vulnerability assessment and weight of the network.
