Description
Secure Shell (SSH) trust relationships enable trivial lateral spread after a host compromise and therefore must be explicitly disabled.
ℹ️ Check
At the command line, run the following command:
# sshd -T|&grep -i HostbasedAuthentication
Expected result:
hostbasedauthentication no
If the output does not match the expected result, this is a finding.
✔️ Fix
Navigate to and open:
/etc/ssh/sshd_config
Ensure the "HostbasedAuthentication" line is uncommented and set to the following:
HostbasedAuthentication no
At the command line, run the following command:
# systemctl restart sshd.service
