Discussion

The resolv.conf (or equivalent) file configures the system's DNS resolver. DNS is used to resolve host names to IP addresses. If DNS configuration is modified maliciously, host name resolution may fail or return incorrect information. DNS may be used by a variety of system security functions such as time synchronization, centralized authentication, and remote system logging.

Check Content

Check the group ownership of the resolv.conf file.

Procedure:
# ls -lL /etc/resolv.conf

If the file is not group-owned by root, bin, sys, or system, this is a finding.

Fix Text

Change the group-owner of the /etc/resolv.conf file to root, bin, sys, or system.

Procedure:
# chgrp root /etc/resolv.conf
