To explicitly disallow remote login from accounts with empty passwords, add or correct the following line in '/etc/ssh/sshd_config': 'PermitEmptyPasswords no' Any accounts with empty passwords should be disabled immediately, and PAM configuration should prevent users from being able to assign themselves empty passwords.


Parameter:

[no/yes]


Technical Mechanism:

Configuring this setting for the SSH daemon provides additional assurance that remote login via SSH will require a password, even in the event of misconfiguration elsewhere.
