The Application Of Information Security Protection System To Network Media

This thesis first surveys the information security architecture and related organizations, criteria, products and gives analysis and conclusion: study on information security assurance architecture has not reached a mature phase, and there has not been a consistent opinion on information security architecture. Then we summarize the development of the Network Media and analyse its current security problem and probable reasons, such as the problem of protocol security, the sensitivity of media, the weakness of basic information industry, etc. Enlightened by the idea of system engineering, the paper gives a dynamic and integrative model (A~2P~2DR~2 model) of information security assurance architecture and designs three lines of defense for the Network Media—protection, detection, response and recovery. Then the paper makes out the further architecture based on the actuality of our Network Media, including the security process and security management such as security maintenance, security rules, security exchange and collaborating, etc. At last we give some advice on further strengthening information security assurance. This paper can also be the reference for Network Media to establish information security assurance architecture.
