Assessment Procedure

Check Text

Locate and examine all r-commands access control files.

Procedure:
# find / -name .rhosts
# more /<directorylocation>/.rhosts

# find / -name .shosts
# more /<directorylocation>/.shosts

# find / -name hosts.equiv
# more /<directorylocation>/hosts.equiv

# find / -name shosts.equiv
# more /<directorylocation>/shosts.equiv

If any .rhosts, .shosts, hosts.equiv, or shosts.equiv file contains other than host-user pairs, this is a finding.

Implementation Procedure

Fix Text

If possible, remove the .rhosts, .shosts, hosts.equiv, and shosts.equiv files. If the files are required, remove any content from the files except for necessary host-user pairs.
