Dynamic Awareness Method for Network Threats
Jieyun Xu, Hongzhen Xu · Advanced science and technology letters · 2015
In order to solve the redundancy question in complex network which is caused by similar attack method and similar node object in attack model, the node domain and transition domain of Petri Net are divided into equivalence classes, and then the construction method of rough vulnerability relation model is given. By defining similar degree of path, search for all of the characteristic attack path which can attain attack object by use of ant algorithm, and calculate the maximal threat of object node which is brought by characteristic strategy.
