【摘要】 近年来在Linux操作系统中出现了入侵Linux内核VFS(虚拟文件系统)驱动程序的后门技术。使用该技术的后门软件能逃脱所有现有的后门检测技术,给Linux系统的安全带来了极大危害。通过分析该后门技术和Linux内核,设计实现了对该类后门软件的检测技术,其效果好于现有的后门检测软件。更多还原

【Abstract】 A new backdoor technology which intrudes VFS (Virtual Filesystem Switch) driver of Linux kernel was introduced two years ago. With it, backdoor software can escape from being detected by existing technology and impair the security of Linux system greatly. Analyzed this technology and Linux kernel, designed and implemented a detecting technology for this kind of backdoor software. The detecting technology is better than existing backdoor detecting software.更多还原
