This paper analyzes the operator’s network security, discusses ways to take a variety of defense and to protect the carrier network to enhance security and stability, while the operator’s network security application technology in-depth research. The paper first discusses operators on the hardware and software vulnerabilities caused by network security threats. It discusses causes of the operator’s threats. By summarizing topological operators, core network and access network a comprehensive analysis of the development process, experience and lessons learned, this paper focuses on two aspects of the operator’s network and application security means. One is from the operator’s network and start its own structure, in the core network, access network and network security applications, technology and other aspects of the operator’s network to optimization and transformation, from the access layer to the core layer, from the ordinary user to line users, from hardware to software to control and optimization; Secondly, according to the specific situation of operators, detailed analysis of the operators to improve network security and network quality of the relationship between the user and the operator’s network planning section lists the operator’s network at all levels of network topology and optimization ideas. In the modern network security technology under the guidance discussed in detail various types of network security technologies such as firewalls, IDS, IPS, encryption, especially analysis of 320 public security solutions, through real case studies, especially for the public security network of this particular industry Security technology in the industry will have a very significant impact, can significantly improve the quality and efficiency of its work to improve the leading technology and security. So I think, strengthen security and application service provider network is the only way for the future communications industry.The purpose of this study are the following aspects:Network security refers to the network hardware, software and system data is protected, not because of accidental or malicious reasons, suffered damage, change, disclosure, continuous and reliable system to run properly, the network service is not interrupted. Network security is its essence on the network information security. Broadly speaking, any information relating to the network confidentiality, integrity, availability, authenticity and control technologies and theories are related to network security research field. Network security is one related to computer science, network technology, communication technology, cryptography, information security technology, applied mathematics, number theory, information theory and other disciplines, comprehensive discipline.As operators we need to take effective measures to protect the operator’s network and information security. And strengthening technical means to take the daily management and sound system closely integrated information and network operators accelerate the security system. Effectively prevent various attacks on information networks, network and information security content security, network security operators to promote the smooth development of.Establish a new network security mechanisms, must be a deep understanding of the network and can provide a direct solution, therefore, the most feasible approach is to develop a sound management system and strict management combined. Protection of the safe operation of the network, making it a good security, scalability and manageability of information network has become the top priority. Once these security risks become a reality, caused by the loss of the entire network are difficult to estimate. Therefore, network operators, network security building construction is an important part of the process.Significance of this study is reflected in the Internet as the progressive realization of the modern computer, Internet prospects of getting better and better, the global economy is entering the information economy, knowledge-based economy began to take shape. Network security and more attention. Network security products have the following major characteristics:first, network security, security strategy and technology from the diversity, if we adopt a unified strategy for technology and also unsafe; Second, the network security mechanisms and technologies to constantly change; Third, as the social aspects of the network extension of the means of access to the network more and more, so network security is a very complicated system. So the future is a security industry with the development of new technology evolving industry. Network security is mainly information security, then the operator’s network security issues become more and more important, whether it is terminal or IP networks, there is a pressing need to ensure safe Internet transmission of online information.As technology advances, operators continue to grow and develop, the importance of network security technology to stand out. To some extent, network operators and terminal equipment, suffered attacks become more serious. Operators each year caused by network attacks, network equipment, hardware and numerous incidents of paralysis, resulting in economic loss is self-evident. Strengthen the network security technology has become a major operator of an issue can not be ignored. The network security marketin an effective operator to apply it, the future operators, key to sustainable development.
