The Scheme And Design Of Security In Qingdao Cable TV Broadband System

The rapid development with computer and communication technologies, the Internet is being greatly applied, network is taken as a tool for the exchange of information, it is the important part of base infrastructure in information of country. At the same time network also includes in negative aspect, it has brought about tremendous challenges for national security of information. Network security of information is a complex system by the physical resources, equipments, technologies etc. It needs us to research and discussion.Qingdao Cable TV network center is a regional video, audio and data network provider, has built digital TV, SDH, ATM and IP integrated networks, and digital TV OSS system, broadband certification system etc, how to manage network security, prevent from illegal attacks, is the responsibility and obligation of network managers. The dissertation bases on what the author actually works for, the information security technologies and situation researched in current network, and the main content proposed. A security management model of Qingdao cable TV broadband system is given, security assessment range,methodology and course of system are discussed. The dissertation gives the design principles of information security in Qingdao cable TV broadband system, with the present realities of system, the OSI basic reference model is used for system security analysis from levels, and the design in every level of system security is analyzed, the design and achievement of security in Qingdao cable TV broadband system are important researched.New security technologies and applications continue to apply in Qingdao Cable TV broadband system, current system runs smoothly. Illegal attacks exist in any times and everywhere, because the security of network is a dynamic process of risk management. Network security is facing immense challenges as a new field of study, its technology and management will be made great progress in the future, the security of Qingdao cable TV broadband system will be improved too.
