In this paper explains simulation and detection attacks on computer networks by OPNET simulator. Intrusion detection at the network and network security are important and considerable issues on IT industry. Hackers use a variety of methods in order to interrupt the normal function of the operating system. Today In the field of defence, firewalls and Intrusion Detection Systems are effective only against known harassment and the respective interruptions are found from their digital signature and perhaps at any moment facing new attacks that are designed. Our work is on the base of simulating a traffic nuisance, depending on the actual packages that are collected from network and including intrusive packages. Using the actual and natural packages in simulation with OPNET enables the Research on strategies and intrusion detection mechanisms and the inauthentic data. In this paper we report our experience in network simulation and its performance by using a firewall in order to evaluate the DoS attacks.
