AIX7-00-002122 - The AIX SSH daemon must be configured to not use host-based authentication.

Information

SSH trust relationships mean a compromise on one host can allow an attacker to move trivially to other hosts.

Solution

Edit "/etc/ssh/sshd_config" and add or update the "HostbasedAuthentication" line as:
HostbasedAuthentication no

Save the change and restart ssh daemon:
# stopsrc -s sshd
# startsrc -s sshd
