The explosive growth of information technology today, the network and the rapid development of computer network is to promote the formation of information technology, digitization and globalization of integrated information system, a variety of network-based applications through the computer network of integrated digital information network collection, storage, transmission, processing and utilization of the human society on a global scale more closely together, and with irresistible trend influence and impact on all aspects of human social, political, economic, and daily work life. Application of enterprise LAN-building more and more, so companies are increasingly being taken seriously LANs become the core competitiveness of key factors. Use of network technology, modern enterprises can optimize communication of information among suppliers, customers, partners, employees, which is directly related to the ability of the business to obtain a key competitive advantage. In recent years, more and more enterprises are accelerating build their own information network, while the vast majority are SMEs, with a lot of use of the mobile terminal, making the network diversification, more intelligent.

This paper mainly depth research and analysis of the Construction and related measures for security management technology enterprise LAN, explore the basic LAN application in enterprise networks, using a variety of common network technology makes the network more secure, reliable, and practical. Combined with the actual needs of the enterprise network to build Zhicheng Technology Co., Ltd. to construct a practical, secure enterprise LAN solutions. The program for the construction of small and medium local area networks, for building enterprise information platform to provide an effective solution.

Keywords: Enterprise Network Port Aggregation Access control VLAN Cyber Security
