摘要
研究解释型病毒的攻击机理,认为其攻击方式和传播对象均与操作系统型病毒不同,传统的计算机病毒定义不能涵盖此类病毒。提出在安全操作系统中增加应用级可执行对象管理器,实现对解释型代码的精确标识,在此基础上提出一种可防止解释型病毒传播的访问控制策略。
Pr inciple of interpreter-level virus is studied.According to the author's resear ch,it differs from operating system virus in ways of attacking and spreading,a nd the traditionally accepted definition of computer virus dosen't cover it.A n ew component named Application Level Executable Object Manager(ALEOM)is intro duced to the architecture of secure operating system to accurately label interpr eter-level codes.An access control policy for the ALEOM to hinder the spread o f interpreter-level virus is presented.
