1. Use a Type 5 password encryption to encrypt passwords, which provides an extremely high level of security and is highly recommended. To use Type 5 encryption, enter the command: “enable secret (your_password)”
2. Use a Type 7 password encryption to encrypt passwords, which is less secure than Type 5 but still more secure than sending passwords in clear–text. To use Type 7 encryption, enter the command: “password (your_password)”
3. Implement Kerberos and Radius authentication for users connecting to Cisco equipment. This provides an additional layer of encryption to passwords used for remote access.
To encrypt clear text passwords in Cisco, you can use the “enable secret” command. This command will encrypt the password with a one-way hash that is very difficult to decrypt. For example, if you wanted to set a password for the “enable” mode of a Cisco router, you would enter the command “enable secret [password]” where [password] is the password you want to use.
