Discussion

SSH trust relationships mean a compromise on one host can allow an attacker to move trivially to other hosts. SSH's cryptographic host-based authentication is more secure than ".rhosts" authentication because hosts are cryptographically authenticated. However, it is not recommended that hosts unilaterally trust one another, even within an organization.

From an ESXi shell, run the following command:

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

Expected result:

hostbasedauthentication no

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