Cluster grids are defined somewhat differently by different people. Some would say that the internet is the world’s largest grid, and others would define a grid as something more controlled. Maybe a network among computers for a certain entity. At any rate, these computer clusters are called grids because they are similar to the electric grid, as the machines are not all housed in the same place. Therefore, security and cluster grids is an ongoing task.
Each operating system within a given grid is called a node. The node may be a PC, an iPhone, or router. Under this definition, the internet certainly functions as a grid. So how are these clusters kept secure? Basically, the network sends tasks to random nodes on the grid to make sure they’re functioning properly and securely. Obviously, malicious programs can infect a grid and cause widespread problems. As work is sent to the various and random nodes, the system waits for two nodes to complete the work with the same result. If a node does not respond, or responds incorrectly, there could be a security issue.
Linux based systems are often touted as the best operating system for cluster grids. One of the arguments is that a Linux system doesn’t slow down a machine when updates are needed. Linux is also open source, so the positive work can be done faster and more thoroughly. If a user were to download a Linux based program, the programmers would ask permission to track any problems with that program. You are, then, participating in open source computing and helping to keep the cluster grid secure. If there is an error or problem with the program on your machine, the programmers can get a report and look at what happened. They can then correct the problem and also identify any security or grid function issues.
Since you are basically participating in grid computing whenever you log onto the internet, your paticipation in security would be to keep your antivirus up-to-date and always operating. Also agree to let open source programmers access your grid programs.
