This object indicates whether a failed SSH login attempt against the device was due to an invalid username or an invalid password. An admin monitoring device security can use this to distinguish between someone guessing at usernames versus someone who has a valid username but is guessing passwords, which suggests different levels of attacker knowledge about the target. If ciscoUrwbFailSshLoginFlag repeatedly shows invalid-passwd for the same known admin account, the admin would suspect a targeted password-guessing attempt against that specific credential.
