Analysis of the communication network of information systems security technology Paper Keywords: communication network information system security protection technology Abstract: Communication networks communication of information systems and communications security threats convenience co-exist, it gives you great convenience of people’s communications, but also the existence of network attacks, malicious network behavior, information theft and other threats to information systems security communications network the problem. Especially into the 3G era, the rapid increase in the number of users to the 3G network the initiator of malicious behavior provides a huge ‘potential client resources.’ In view of this situation, this article focuses on the communication network to ensure security of information systems related to protection technology . 3G mobile communications technology and network communication technology is now widely used for people to fully experience the high-tech offering. Communication network information system as an open communications with higher technology platform, its security technology research and study has important practical significance and value. 1 common communication network information system security threats First, take the initiative to capture user identity information to launch malicious behavior will disguise themselves and then to request the identity of the target network service authenticates the user, then the user’s identity information to obtain the second, interfere with the normal services according to different levels of interference can be divided into: (a physical level of interference: the behavior of those who launched the malicious use of physical means, or interfere with the system related technologies wireless link, resulting in the user data and signaling data can not be transferred, (2 protocol level interference: the malicious behavior launched by means of the use of a process leading to failure
