Fix Recommendation

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.

Check Contents

To determine how the SSH daemon's "PermitEmptyPasswords" option is set, run the following command:

# grep -i PermitEmptyPasswords /etc/ssh/sshd_config

If no line, a commented line, or a line indicating the value "no" is returned, then the required value is set.
If the required value is not set, this is a finding.
