The Research About The Firewall Testing

The network security question innate network that day got up has existed, only was the people certainly not notice at that time. Along with the computer dependent on network more and more, the network security question was also obvious. The information security product, reliability is affecting the national security and the economy, so it must be carried on authoritative and the fair test and the appraisal by the authoritative organization, confirmed them that had achieved the certain standard security rank, guaranteed satisfy the user's requirements.The firewall basic concept is a system or a group of systems, it between the net and the Internet carries out the certain security policy in the enterprise. An effective firewall should be able to guarantee: all will come from the Internet or flow to the Internet information must pass through the firewall; all class received after the firewall information are inspected. As the control method of the network ,the firewall already became the universal application network security equipment, also became the guarantee of the important barrier of the network. Using the level firewall production is the source to the information network security demand , but tested for this kind of product appraisal and the approval has provided the most credible basis, therefore, it is necessary to measure test more through research to this kind of product.This thesis explain the network security issue and for defence threaten form network, protecting the security we adopt the technology of the firewall. It havedescribed the reference utilized in a grade of test criterion and course of testing based on firewall that has tested platform and common tools; regarded testing the agent server as the focal point, tested content and compared the relatively argumentation in using a grade of firewall; have introduced the test tools -used and acted as agent of the safe protection of firewall outline and tested the system. I has put several improvement measures to improve the system.
