What is Multi Agent Systems

The computer sciences and their applications are developing continuously. This growth should be protected. One of the methods to fulfill this approach by using the encryption method ‘Rijndael Advanced Encryption Standard' is applied for security information DBs, to prevent an unauthorized user from accessing any stored information. The security method determines the resources that agents are able to have an access and to give permission to other agents. Security and security assurance are special integrity in agent system to enable it to cooperate or to complete the application and where agent system may not be trustful to visiting agents. Ideas of this chapter of using multi agent framework is to design the proposed Automatic Intrusion Detection model and to secret multi agent preservation using authentication measurement network threat. This approach uses statistical models to correlate and analyse data in the network. It takes the decisions to control both local and global agent's data bases perceptively. Also it adopts the security problem authentication and authorization by providing a secure distributed agent system.
