Abstract:- Context awareness network security is an effective solution to the problems, network systems are suffering from, such as worms, virus, network eavesdropping, sniffing etc. Traditional security controls exist but they operate exclusive to one another and cannot provide evaluation of threats. The false positive and negative rates of these devices are too high. Hence it is very difficult to obtain the security state of the whole network. This paper proposes Knowledge based Context Awareness Network Security (KCANS). The security alert events are gathered from various network security situation sensors which are then analyzed and fused using D-S evidence theory as fusion mechanism. Network security context is generated by extracting frequent attack patterns based on knowledge discovery method. Performance analysis shows that the proposed system have improved results in terms of average end to end delay, average energy consumption, packet delivery ratio and throughput as compared to without knowledge discovery technique.
