In most organizations currently, a security management process consists of three independent domains; physical security domain, managerial security domain and technical security domain. It is very difficult to link these domains as the manager and managed objects are different although the security system is under the same governing structure. In other words, even when each security system is properly established, it is difficult to prevent or respond the security accident enterprise-wide when vulnerability is generated in a domain. This paper is based on the Network security situation awareness. It describes the framework designed to generate security graph. The proposed framework is easy to install and provides protection against denial of service and distributed denial of service attacks.
