Discussion

The .rhosts, .shosts, hosts.equiv, and shosts.equiv files are used to configure host-based authentication for individual users or the system. Host-based authentication is not sufficient for preventing unauthorized access to the system.

Check Content

Check for the existence of the files.

# find / -name .rhosts
# find / -name .shosts
# find / -name hosts.equiv
# find / -name shosts.equiv

If .rhosts, .shosts, hosts.equiv, or shosts.equiv are found and their use has not been documented and approved by the IAO, this is a finding.

Fix Text

Remove all the r-commands access control files.

Procedure:
# find / -name .rhosts -exec rm {} \;
# find / -name .shosts -exec rm {} \;
# find / -name hosts.equiv -exec rm {} \;
# find / -name shosts.equiv -exec rm {} \;
