Semantic similarity analysis model for CND policy and measure
Senshen Hao, Jian Jiao, Chunhe Xia, Xiaojian Li, Shan Yao · 2010
In order to effectively deal with large-scale attacks on computer networks, Computer Network Defense (CND) policy refinement based on descriptive language is wildly used. However, it's very difficult to figure out the semantic discrepancies between the measures and the predefined policy after the calculation with symbols by computers. A new method is presented to solve the discordance of semantic between the measures and the predefined policy automatically. Based on the establishment of the ontology of CND policy and measure (CNDPM), the CND policy and measure semantic similarity analysis model (CNDPMSSAM) is established, and then the termination of the two main components of CNDPMSSAM are proofed by the putdown automaton, and the prototype system of CNDPMSSAM is implemented. At last, we validate the validity of this method on analyzing semantic similarity of transferring from Computer Network Defense Policy Specification Language (CNDPSL) to Defense Measure Description Language (DMDL) with experiments.
