当今的计算机系统是脆弱的,它受到来自內部的滥用和外部的侵入,这可由报纸上报导的日益增多的破坏事件表明。要想弥补当今系统所有的安全漏洞是不可能的,任何技术的组合也不能阻止系统的合法用户滥用他们的权力,于是审计被认为是最后一道安全防线。 Today’s computer system is fragile, it is abused internally and externally by intrusion, as evidenced by the growing number of sabotage incidents reported in the newspapers. It is impossible to make up for all the security holes in today’s systems, and no combination of technologies can prevent legitimate users of the system from abusing their power, so auditing is considered the last line of defense.
