Synopsis:   

With great computing power comes great responsibility. Security is of utmost importance in a grid environment. Since a grid performs large computations, data is assumed to be available at every node in the processing cycle. This increases the risk of data manipulation in various forms. Also we have to keep in mind what happens to the data when a node fails. An ideal grid will have a small time of convergence and a low recovery time in case of a complete grid failure. By convergence, we mean that each and every processor node will have complete information about each and every other processor node in the grid. Recovery time is the time it takes for the grid to start from scratch after a major breakdown. To put things in the right perspective, a good grid based computing environment will have an intelligent grid administrator to monitor user logs and scheduled jobs and a good grid operating system which will be tailor made to suit the application of the grid. We propose a similarity between the OSI model and a Grid Model to elaborate the functions and utilities of a grid. There have been numerous previous comparisons and each is knowledgeable in its own right. But a similarity with a network model adds more weight since physically a grid is nothing but an interconnection, and interconnection can be best defined in relation to a computer network interconnection. We proposed a secured grid model for the distributed applications in the grid computing environment.
