随着信息技术的迅速发展,随之而来的通信网络安全问题也日渐凸显,如病毒,黑客等等窃取信息的方式也不计其数,因此,如何应对这些通信网络出现的安全问题,是目前通信工程需要急待解决的,本文就针对当前通信网络行业出现的安全问题做了详细的分析,并具体的介绍了常用的几种通信网络安全防护技术,针对这些技术的优缺点,提出了一些看法。 With the rapid development of information technology, the ensuing problems of communication network security have become increasingly prominent. There are also many ways to steal information such as viruses, hackers and the like. Therefore, how to deal with the security problems in these communication networks is the current Communication engineering needs to be solved urgently, this paper analyzes in detail the security problems in the current communication network industry, and introduces several commonly used communication network security protection technologies. In view of the advantages and disadvantages of these technologies, some suggestions are put forward view.
