Method on Network Information System Security Assessment Based on Rough Set
Qiangmin Wang, Lin Mengquan, LI Jian-hua · 2007
Based on the analyzing the concept of network information system security assessment, this paper proposed an information system security basic attribute model for information system security assessment based on optimal security tree criteria. Then a novel heuristic rough set attributes reduction algorithm was proposed to reduce the attributes and build weight set. The validity and practical value of it were illustrated by an example. The main idea of the security assessment is improve the assessment efficiency and reduce the cost.
