Title

There must be no .rhosts, .shosts, hosts.equiv, or shosts.equiv files on the system. (Cat I impact)

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 / -type f -name .rhosts # find / -type f -name .shosts # find / -type f -name hosts.equiv # find / -type f -name shosts.equiv If .rhosts, .shosts, hosts.equiv, or shosts.equiv are found, this is a finding.

Remove the .rhosts, .shosts, hosts.equiv, and/or shosts.equiv files.
