Discussion

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

Check Content

From an ESXi shell, run the following command:

# /usr/lib/vmware/openssh/bin/sshd -T|grep permitemptypasswords

Expected result:

permitemptypasswords no

If the output does not match the expected result, this is a finding.

Fix Text

From an ESXi shell, add or correct the following line in "/etc/ssh/sshd_config":

PermitEmptyPasswords no
