我正在思考CISCO Ios命令的基础知识,我正在努力找出以下问题的答案:
当您设置密码以允许特权EXEC时,什么可以提供更好的保护
要么
什么是更好的方式来设置密码并encryption? 哪一个使用更好的encryption?
谢谢,Dempsey
下面是我能解释的最好方法:
底线,尽可能使用启用密码,明文密码永远不是好事。
设置密码并在cisco设备中encryption的更好方法是使用命令enable secret password它使用MD5algorithm或SHA 256来散列密码。
service password-encryption较弱,因为:
service password-encryption allows you to encrypt all passwords on your router so they can not be easily guessed from your running-config. This command uses a very weak encryption because the router has to be very quickly decode the passwords for its operation. It is meant to prevent someone from looking over your shoulder and seeing the password, that is all.
希望这可以帮助。
