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 mode of the /etc/resolv.conf file.
# ls -l /etc/resolv.conf
If the file mode is not 0644, this is a finding.

Fix Text

Change the mode of the /etc/resolv.conf file to 0644.
# chmod 0644 /etc/resolv.conf
