上游充通大学 SHANGHAI JLAO TONG UNIVERSITY Linux安全吗? 一个最大的误区就是很多高性能的安全操作系统 可以预防计算机病毒。 另一个误区就是认为Liux系统尤其可以防止病 毒的感染,因为Linux的程序都来自于源代码, 不是二进制格式。 第三个误区就是认为Linux系统是绝对安全的, 因为它具有很多不同的平台,而且每个版本的 Linux系统有很大的不一样。 信息安全工程学院

上游通大学 SHANGHAI JLAO TONG UNIVERSITY Linux病毒列表 ① Slapper:The most dangerous Linux worm;it's network-aware and in August 2002 it exploited a flaw in OpenSSL libraries in Apache servers with OpenSSL enabled. Bliss:Also a well-known bug,it infects ELF executables,locating binaries with write access and overwrites those with its own code. Staog:Considered the first Linux virus,it infects ELF executables. Typot:A Linux Trojan that does distributed port scanning,generating TCP packets with a window size of 55808. Mydoom Windows worm have network propagation and process termination capabilities to launch a denial of service (DoS)attack on www.sco.com. 信息安全工程学院
