In India too, various ministries of Govt. of India and State Governments have taken e-governance initiatives to provide e-services to citizens and the business they serve. To achieve the mission objectives, and make such e-governance initiatives successful it would be necessary to improve the trust and confidence of the stakeholders. It is assumed that the delivery of government services will share the same public network information that is being used in the community at large. In particular, the Internet will be the principal means by which public access to government and government services will be achieved. To provide the security measures main aim is to identify all possible threats and vulnerabilities according to the data locations and then according to the models of Nath¡¯s approach. Based on this analysis, the security requirements of the data and the applications have been formulated in the form of security parameters like confidentiality, integrity and availability. This analysis leads to the security architecture of the specific G2C application. %K G2C %K Broadcasting model %K Critical flow model %K Comparative analysis model %K E-advocacy model %K Interactive model %K confidentiality %K integrity %K availability %K authentication %K non-repudiation %K egovernance %U http://www.sersc.org/journals/IJUNESST/vol3_no2/2.pdf
