Proposal for integrated system architecture in utilities

For the public usage, there are various utilities that exists and operates in many countries. Major utility are in the sector of Power, Gas and Water distribution. Their major role is to distribute the essentials to the customers and in turn provide Customer support and Billing system through offline and online mode. Most of them fall under government control but may be managed by Franchise or Public private partnership model. All of them have individual existence in Delhi, India. We propose a common architecture through which the information systems and related processes can be merged for these utilities which will benefit the customers. The security analysis is done for the proposed architecture with respect to various threats.
