Development of information technology makes the application of computers has spread to every corner of the world. Many enterprises have to rely on IT technology to build the enterprise's own information systems and business operations platform. IT network use has greatly enhanced the core competitiveness of enterprises so that enterprises can emerge in the information the information age. Enterprise use of communications networks to connect isolated stand-alone system, mutual communication and sharing of resources. However, computer-based information sharing and the openness of the Internet's unique, making enterprises increasingly serious problem of information security.

External security With the development of the Internet, network security event after another. In recent years, computer virus, worm attacks, spam, sensitive information leaks, etc., have an impact on the most widely security threats. For enterprise users, when faced with these threats often lead to data corruption, system abnormalities of the networks, information theft, reduces efficiency, direct or indirect economic losses are also high.

Internal security Latest survey shows that companies under investigation for more than 60% of employees use the network for personal reasons. Improper use of the network, reduce productivity, hinder computer network, enterprise network resource consumption, and the introduction of viruses and spyware, or employees can make illicit leakage of business secrets through the network, thus resulting in tens of millions of dollars in losses.

Between the internal network, the connection between internal and external network security

With the development and growth of enterprises and the mobile office popularity, gradually formed a corporate headquarters, local branches, mobile workers such a new interactive mode of operation. How deal headquarters and branch offices, mobile workers to share information security, it is necessary to ensure the timely sharing of information, but also to prevent the leakage of confidential business growth has become the process had to consider. Institutions and around the headquarters of the network connection between the security of the efficient operation of enterprises directly affected.

1. SME Network Analysis SMEs because of their size, industry differences, work and management practices of different organizations have different network topologies. Network under the following conditions.

Centralized: SME networks are generally only set up a complete network based layout. Dedicated to access, ADSL access lines or access to other network access methods, the total number of common network devices range in the tens to hundreds. Some of the network division of the subnet, and deployed with the core business-related servers, such as database, mail server, document database, or ERP servers.

Distributed: Take office and mobile multi-way branch, the branch network are deployed, not much. Dedicated access to a large branch, general branch means access to ADSL. Mainly through the VPN to access the host device and database company, by mail or internal network for business communication.

Integrated: Centralized and decentralized integrated. Integrated enterprise network diagrams 2. Network security design principles Network security system is to achieve the core objectives of network operation system and application of effective control and management. Any security system must be based on technical, organizational and institutional foundation of these three.

System design principles Level by analyzing the relationship between information networks and put forward the scientific and security framework security system, security system based on analysis of the various forms of security risks, thus maximizing the potential security problems to solve.

Global integrated design principles From the actual situation of SMEs, relying solely on a security measure, and can not solve all security problems. Recommendations take into account a variety of security measures for the use of a very high degree, scalability, strong security solutions and products.

Feasibility, reliability and safety The fundamental feasibility of security solutions that will directly affect the smooth flow of network communications platforms, security systems and network reliability is a communication platform to ensure the normal operation, but security is the ultimate goal of designing secure systems.

3. Overall network security architecture Security program must structure the scientific network security systems architecture, security architecture because it is a safe basis for design and analysis.

Overall security architecture With the application layer attacks for more and more a growing threat, only for the following network layer security solutions have been insufficient to meet the attack from the application layer. Here is a simple example, those carrying the worm backdoor program is a simple firewall / VPN security systems are not able to cope. We therefore propose to use three-dimensional multi-layered enterprise security architecture. Shown in Figure 2, this multi-layered security system not only requires the boundary set in the network firewall / VPN, but also set against network viruses and spam and other application layer attacks, protective measures, the application layer of protection on the network edge, This active defense can stop the attack entirely outside the corporate intranet.

1. The whole security system The above planning and analysis, the proposed SME enterprise network security system in accordance with the system to achieve the purpose, using a security gateway integrated with high reliability to achieve the following system functions:

Firewall VPN system Intrusion Detection System

Network Behavior Monitoring System Spam filtering system Virus scanning system -Bandwidth management system Wireless access system 2. Programme proposals 2.1. Overall network security solutions

Through the above needs analysis, we recommend the following overall network security solutions. Network Security Platform consists of the following components:

Firewall: A firewall system to achieve the internal network and wide area networks in isolation protection. Server on the internal network separate sub-networks based firewall for protection.

VPN system: remote and branch office staff to facilitate the IPSecVPN access, protection of data transmission security, realization of users controlled access to the server system.

Intrusion Detection System: The intrusion detection device, functions as a firewall complementary control segment provides real-time attack
