Security Knowledge Representation of e-Government Data Centre Through Ontology

Abstract

Security knowledge is the heart of an e-government data centre. The knowledge refers to information gained through learning and experience. It is well known that security requirements of a community data centre are changing rapidly which are mostly formless and lack formal representation yet. It is therefore, felt essential to have a model for a community data centre that can support knowledge sharing and reuse in an explicit and mutually agreed manner. We have developed a security knowledge-based, ontology-centric framework for e-government data centre. Our framework that demonstrates correlation between high-level policy statements based on information system security standards and deployable security controls which are implementable and the objectives are achievable. This framework may support security expert activities with respect to security requirements, application and management of respective security controls and their countermeasures. We have tried to implement our model in a neutral manner.
