Network Security Situation Awareness (NSSA), in large-scale network environment, can deal with the security elements which caused network security situation changed. This paper considers the use of rough set in incomplete-based systems to security awareness. The paper firstly introduce the system structure and rough set relevant background knowledge, then establish security situation awareness model based on rough set under incomplete information system. Through the reduction of condition attributes and attribute values for quantitative classification, get the value of the security awareness to achieve assessment of network security awareness.
