Domestic Linux Server Application Security Research

The network server platform which based on the Linux operating system has the very famous superiority, using the domestic Linux construct low cost, the safe public information platform realization electron government affairs and other applications may practically solve the digital gap problem. But by no means the simple system integration and the combination can realize the safe reliable service and apply the platform, it has many technical and security problem needs to be solved.The thesis take the domestic Linux server application as the starting point, has done the correlation research of the Linux server application secure strategy, it include the disposition management, the boundary protection, the viral guard, the safety control and various types network attack and the corresponding revision measure.This article divides into six parts. The first part discussed the thesis topic selected significance, the domestic and foreign present situations and the main content of research. The second part introduced elementary knowledge of the main correlation technology. The third part simple described the platform construction foundation, and then proposed the realization security system construction for solutions some security problems which exist in the application, and emphasis elaborated the overall secure strategy and some attack and defense measures. The fourth part discussed the concrete application technology of firewall and the Snort invasion Detect system, attempt proposed use snort in the practical application, as well as combine with the firewall technology, perfect network application security. The fifth part described the evaluation of application effect, unifies predecessor's experience and author's attainment, through the design concrete test plan, has made the examination to the system security .The sixth part is a conclusion, summarized the thesis research results of this thesis and put forward my own suggestions.
