======6.2.14 Ensure no users have .rhosts files (Scored)======
=====Profile Applicability=====
Level 1 - Server
Level 1 - Workstation
=====Description=====
While no ''.rhosts'' files are shipped by default, users can easily create them.
=====Rationale=====
This action is only meaningful if ''.rhosts'' support is permitted in the file ''/etc/pam.conf''. Even though the ''.rhosts'' files are ineffective if support is disabled in ''/etc/pam.conf'', they may have been brought over from other systems and could contain information useful to an attacker for those other systems.
=====Audit=====
Run the following script and verify no results are returned:
#!/bin/bash
for dir in `cat /etc/passwd | egrep -v '(root|halt|sync|shutdown)' | awk -F: '($7 != "/usr/sbin/nologin") { print $6 }'`; do
for file in $dir/.rhosts; do
if [ ! -h "$file" -a -f "$file" ]; then
echo ".rhosts file in $dir"
fi
done
done
=====Remediation=====
Making global modifications to users' files without alerting the user community can result in unexpected outages and unhappy users. Therefore, it is recommended that a monitoring policy be established to report user ''.rhosts'' files and determine the action to be taken in accordance with site policy.
