分层式防护在广播电视网络安全防护中的应用

广播电视网络是我国重要的信息传输渠道,新世纪以来我国的信息化进程不断加快,广播电视网络和计算机通信网络在金融、政治、交通、军事等领域中发挥着越来越重要的作用。数字电视网络、通信网络以及计算机网络为代表的三大网络是社会发展中最为重要的基础性网络。"三网合一"技术为社会发展所带来的便利性极大,同时"三网合一"后所形成的通信网络是社会发展中最重要的基础性设施之一。随着通信技术的不断发展,广播电视网络的应用层面不断加深,尤其是随着新一代的IPV6技术应用的不断推进使得广播电视网络在社会发展中的地位不断提升。广播电视网络作为最重要的信息渠道之一应当注意做好网络安全防护,针对广播电视网络的安全结构应当注意采用网络分层保护的思想,针对各层网络的特点采取针对性的网络安全保护措施,最大限度地确保广播电视网络的安全。

Radio and television network is an important channel of information transmission in China. The information process of our country has been speeding up since the new century. Radio and television networks are playing a more and more important role in the fields of finance, politics, transportation and military affairs. Communication network and computer network are the most impor-tant basic networks in social development. The ＂three nets in one＂ technology brings great convenience to the social development. At the same time, the communication network formed after the ＂three networks in one＂ is one of the most important basic facilities in the social development. With the continuous development of the communication technology, the application level of radio and televi-sion network is deepening, especially with the development of the new generation of IPV6 technology, thus the status of radio and television network in the social development has been improved. As one of the most important information channels, radio and televi-sion networks should pay attention to the network security protection, and to the security structure of radio and television networks, and we should pay attention to the idea of network layered protection. According to the characteristics of each layer of network, take measures of targeted network security protection to maximize the security of radio and television networks.
