Objectives: This paper proposes a formal model for network security situational awareness which supplements most of the gaps faced in traditional approaches of network security and provides formal representation and functional prototype of National Social Security Authority (NSSA). Methods/Statistical Analysis: Semantic Web based approach and Resource Description Format (RDF) is used for implementation of the formal model. Besides, a novel capability to increment knowledge base of the system has been devised so that the system may adapt to dynamic network structure as per perception of network administrator. Secondly the ability to perceive a particular situation in a specific manner is to be incorporated in the system by network administrator. This capability empowers the administrator to secure network infrastructure in own fashion in a specific context instead of using a generalized security policy. Findings: We have conducted a number of experiments to measure the performance of our proposed framework on a software simulated environment. We have quantified the performance overheads of our proposed framework for measuring the inference time and response time. All the experimental results have shown that our framework has satisfactory response as far as the performance is concerned and for the better performance, more powerful machines can be used. Application/ Improvement: This approach provides a non database semantic approach which can be used to semantically correlate information, thus providing an affective mental model to deal with complex network situations.
