Distributed Systems

That means that with the network operating system we can have lots of users all concurrently using resources on our serve.One of the most important aspects about server operating systems is the security. Workstation OS provides great security for end-users, but it's still not as tight as the security offered by the network operating systems.

The central node is the distributed database and it is a single logical database which is spread across different local computers and they are all connected over a network.

To make matters worse both Target and Sony were actually warned about the flaws in their security, but neither took any action to resolve the flaws. Looking into these breaches and how they were handled could lead to designing better databases. Organizations should also look within themselves to assure all employees know good security practices. Simply following regular procedures such as installing antivirus software and firewalls can help create more secure databases. An organization should look at all of their databases to ensure the same top level security is established for all of their databases.
