Network security has a very vital role in provisioning of accurate and reliable operation in wide distributed networks. The rapid evolution of interlinked network and the ever increasing volume of data exchange have resulted in raise on new threats of attacks and network vulnerability. Need of developing new approaches in security provision hence evolved as a challenging task in data exchange. This research focus on developing methods to overcome different attacks over a wide network using topology based security approach. Topology based approach use the deployment of nodes and links to model...
