在正常操作模式下使用show version命令(完全Cisco IOS映像)查看您的引导映像,以查看引导映像是否支持enable secret命令。如果是,请删除enable password。如果引导映像不支持enable secret,请注意以下警告: 如果您具有物理安全性,则无需使用启用密码,这样便没有人可以将设备重新加载到引导映像。
但是,service password-encryption命令使用的算法是简单的Vigenre加密。此算法甚至无法阻止稍微有些老练的攻击者对配置文件进行深入的分析,因此不能用于上述目的。任何包含加密口令的 Cisco IOS 配置文件,都必须和这些口令的明文列表一样受到严密的保护。 虽然enable secret命令并不使用这一加密强度较低的加密算法,但enable ...
