Paper Title
Evaluating Performance of a Secure Computer Network System by using VPN Based on IPSEC

Virtual private network (VPN) is saving a solution of security to the network nodes. that is by applying tunnels between specific the nodes. Nevertheless, the VPN connection affects the operation of the network depending on the traffic intensity. In this paper VPN network is suggested for network security to implementing of other network performance metrics like throughput and time delay. It is also tested under different traffic generators like constant bit rate (CBR) and file transfer protocol (FTP) payloads because of intensity the effects of the VPN tunnel on network performance. Also, other method used for attacks prediction called as Artificial Neural Network which represents a deep learning technology to predict any attack by learning the attacks behaviors during the training stage. Keywords - Attack, CBR, Delay, Deep Learning, FTP, Network Security, Throughput, VPN.
