Assessment Procedure

Check Text

The files hosts.equiv (/etc) and .rhosts (in the user home directory) contains host/user pairs to be trusted by the local system.  

Locate the files:
# ls -l /etc/hosts.equiv
# find / | grep .rhosts
or
# cd <user's home directory> 
# ls -l .rhosts

If the hosts.equiv file or one or more .rhosts files are found, this is a finding.

Implementation Procedure

Fix Text

Remove the file(s):
# rm -f /etc/hosts.equiv
# rm -f <user's home directory>/.rhosts
