Methods for strengthening a Computer network security

Information security is an important aspect that must be maintained in order to obtain a successful business. However, financial difficulties and budget constraints create problems in selecting security countermeasures to maintain the network and running the system. Network administrators must rely on labour-intensive processes for tracking network configurations and system vulnerabilities, which needs a lot of expertise and will cause an error prone. Organizational network vulnerabilities and interdependencies are so complex to make traditional vulnerability analysis become not adequate. Decision support capabilities let analysts make the balance between security and availability, and show how best to apply limited security resources. In this paper, we present a methods for strengthening a computer network security.
