Paper Title
Design and Analysis of Network Security Model

Network security is a term which consists of policies and procedures adopted to prevent and monitor the unauthorized access, modifications or denial of computer network and the resources. With an increase use of networking applications for information sharing, there is a need to protect this information from modification or malicious behaviour. With an advent use of new technologies such as Cloud Computing, E-Commerce, the network security has still remained as an increasing challenge. Securing a network has become the need and to address the core issues of securing the information into different networks, a secured network architecture is essential. Making a use of secure network, protects it from outside attacks and threats with denial of unauthorized access. A contribution to the study of network architecture model can be followed by building a robust and flexible network that responds to the future requirements as well.
