Title

The .rhosts file must not be supported in AIX PAM. (Cat II impact)

Discussion

.rhosts files are used to specify a list of hosts permitted remote access to a particular account without authenticating. The use of such a mechanism defeats strong identification and authentication requirements.

Check Content

Check the PAM configuration for "rhosts_auth" using command: # grep rhosts_auth /etc/pam.conf |grep -v \# If a "rhosts_auth" entry is found, this is a finding.

Fix Text

Edit "/etc/pam.conf" and remove the reference(s) to the "rhosts_auth" module.
