The novel concept of grid computing, clusters of computational power is constructed from a network of many small and widespread different computers servers or workstations into a single resource. We now proceed to translate the grid security problem into specific grid security requirements. The purpose of Grid technologies is to support the secure sharing and scalable coordinated use of diverse resources in dynamic, distributed VOs. We propose a secure blueprint design for grid systems that addresses requirements for single sign-on, interoperability with local policies of any grid city of India, with dynamically varying resource demands.

In current scenario, there are always impending threats from militants and terrorists within and out of a country. The sensor networks play a vital role in minimizing the loss of human lives in the event of usual calamity and artificial sabotage created by terrorists. The sensor networks can be successfully deployed in any difficult geographical terrains where manual round-the-clock surveillance is highly impossible. Energy aware routing is immensely helpful to sensor networks in the aspect of extending the life span of the WSNs. In this paper, an automatic suspected terror system based on wireless sensor networks is developed, which is designed for high-rise metro structure. In order to provide early extinguish of impending threats by putting any bomb, large numbers of detectors which periodically measure noise, smell, infringement, vibration, temperature concentration, unidentified stranger photo are deployed from major streets. Those scattered detectors report their monitoring information to the surveillance center via the self-organizing hierarchical intelligent wireless sensor networks (IWSN). Test results from it show that the automatic suspected terror system achieves the design requirements.
