Network security solution
1) Definition of small and medium enterprises Small and medium-sized enterprises are defined as regional offices, branch offices, headquarters of medium-sized enterprises, etc. 2) The current situation of small and medium enterprises network The network status of medium-sized enterprises is as follows: the number of network information points is 50-500; the network construction has a certain scale, with large-scale network equipment, such as routing switches Router, etc.; Internet connection through dedicated line; mobile users need to access the enterprise network; independent information publishing system, such as web and mail server. Through the analysis of the above network status, combined with the actual situation of medium-sized enterprises, we believe that the network security of medium-sized enterprises mainly faces the following problems: a: After the network is connected to the Internet, the gateway needs to be protected to prevent hackers and viruses from attacking the network; b: Mobile users access the enterprise network without any encryption through the Internet, which may cause the theft of important data of the enterprise; c: Network virus is the biggest threat to enterprise network security, which may cause serious consequences such as operating system crash, data loss and network paralysis d: Due to the independent information publishing system, such as web and mail server, centralized security protection is needed to ensure the normal operation of these systems The operation of the system e: Due to the large number of computers in the enterprise network, the operating system patching, application software distribution, computer asset management, computer operation monitoring and other repeatability Work, a serious impact on the efficiency of the network management department, so that the cost of enterprise maintenance is greatly improved. 4) Network security solutions for medium sized enterprises In view of the above medium-sized enterprise network problems, we propose the following network security solutions: configuration of a firewall, gateway protection, prevent hackers, disease In order to attack the internal network and access mobile users through VPN function of firewall, the firewall model can be selected according to the following corresponding relationship; Number of users firewall model VPN channel Configure a set of kill security armour network anti-virus system to prevent the operating system from infecting virus and prevent the spread of network virus; configure a kill Filtering Gateway: KSG 500, the gateway anti-virus, and security protection of information publishing system; configuration of a kill terminal security management system, can effectively control the enterprise network There are computers for asset management, system patch distribution, application software distribution, computer operation status management, so as to greatly improve the work efficiency of network management department To improve the efficiency and reduce the cost of enterprise network operation. The network structure is as follows: The above network security solutions for small and medium-sized enterprises have the following advantages: a: "Juniper NetScreen is the largest firewall / VPN equipment manufacturer in the world. Its products have excellent success cases in various industries, and its strong technical support is very important Technical advantages and our excellent after-sales service ability will eliminate worries for users; b: "Firewall and VPN are integrated in the same device, which simplifies the network structure, reduces the equipment investment, and reduces the difficulty of gateway equipment maintenance;" kill security Armour network anti-virus system is an anti-virus system certified by the Ministry of public security. It has powerful functions, can check and kill all viruses, and can automatically update all users , automatic upgrade. c: "Through the double authentication of the Ministry of public security, the filtering gateway can filter viruses, worms, spam and sensitive content, so as to improve the overall security level of the network A new step has been taken; d: "The terminal security management system provides a comprehensive technical support for the end point lifecycle management (ELM) strategy, including Cover asset management, terminal protection, application supervision, audit analysis, etc., and combine terminal security, management and maintenance with its business objectives to ensure the continuous development of computer terminals Effective operation. Due to independent research and development and focusing on the needs of domestic users, it is closer to the actual use situation of domestic users, and can be customized according to new needs development. |
