Discussion

The warning message reinforces policy awareness during the logon process and facilitates possible legal action against attackers. Alternatively, systems whose ownership should not be obvious should ensure use of a banner that does not provide easy attribution.

Check Content

From an ESXi shell, run the following command:

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

Expected result:

banner /etc/issue

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":

Banner /etc/issue
