硬件防火墙的四大选购要素之分类介绍（Classification of four major purchasing factors of hardware firewall） We should use as many advanced technologies as packet filtering, encryption, reliable information technology and so on. Such as identification and authentication, confidentiality protection of information, integrity verification of information, access control mechanism of the system and management of authorization, all of which are necessary for firewall security system. The Nokia firewall of Xiao Tongs agent uses a dedicated IPSO security operating system and a specially developed hardware platform to ensure the high security of the system platform itself. On this platform, Nokia and integrated CheckPoint, SecoSheild, WebSense and other security products, to achieve comprehensive security. These products provide security guarantees for users while providing flexibility and variety of strategies. Efficient performance and high reliability The firewall is to filter incoming data to identify compliance with security policies, so the higher requirements in the flow, the firewall can be the fastest time for all test packets, otherwise it may cause the delay, or even crash. This metric is important because it reflects the usability of the firewall and reflects the cost (delay) of the firewall products used by enterprise users, and the user can not accept the exorbitant cost. If the firewall causes great delay to the network, it will cause great loss to the users. At this point we use the personal firewall may have deep feeling, sometimes we open the firewall when the Internet was very slow, and once removed speed up, the reason is because the firewall filtering fast enough. If the firewall has too much influence on the original network bandwidth, it will undoubtedly be a huge waste of the original investment. At present, the firewall type basically realize the conversion from software to hardware, the algorithm also has great performance optimization, a part of the firewall can affect
