中文摘要：

基于进程行为的入侵检测技术是主机防范入侵和检测恶意代码的重要技术手段之一．该文提出了一种基于可执行文件静态分析的入侵检测模型，该模型通过对应用程序可执行文件的静态分析，建立应用程序所有可能执行的定长系统调用集合，通过实时监控进程执行的系统调用序列是否在该集合中实施检测．该模型不需要源文件、大规模训练数据，通用性和易用性好；在应用程序可执行文件完整的情况下，误报率为0，抵抗模仿攻击的能力更强，漏报率更低．

英文摘要：

Intrusion Detection based on process＇ behaviors is one of the mainstream techniques for defend against intrusion and malicious code. In this paper, an intrusion detection model based on executable static analysis has been brought forward. The model statically analyzes the executable files of the application to construct the set When monitoring in real time, it splits the of all the possible N-length system call sequences. system call sequence the process triggered into N-length sequences by N-length slide window. If there is one in the N-length sequences not in the set, the process is marked as intrusive. The model needs not source code or large numbers of training data, and is much more universal and applicable. When the executable files of the application are complete, the rate of false positive is 0. It＇s much stronger for defending against mimicry attacks and its rate of false negative is much less.
