Description
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.
ℹ️ Check
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
From an ESXi shell, add or correct the following line in "/etc/ssh/sshd_config":
Banner /etc/issue
