What command is used to increase password security on a Cisco device?

• A. enable password
• B. service password encryption
• C. set password
• D. encrypt password

Answer: (B)

The command that is used to enhance password security on a Cisco device is "service password encryption." This command ensures that all passwords stored in the device’s configuration file are encrypted, making it more difficult for unauthorized users to read sensitive information in plain text. When this command is applied, it protects both the enable and line passwords, thereby adding an essential layer of security to the device’s configuration. Using "service password encryption" is a best practice for network security, as it helps safeguard password information against discovery should someone gain access to the device's configurations. This command employs a simple but effective encryption method rather than leaving passwords in plaintext, which can be easily viewed by anyone with access to the device's configuration. Other options, although related to password management, do not provide the same level of security through encryption. For instance, enabling a password or setting a password might establish the password policy on a device, but without employing encryption, the passwords remain vulnerable.
