Check: GEN001364

HP-UX 11.23 STIG: GEN001364 (in version v1 r8)

Title

The /etc/resolv.conf file must have mode 0644 or less permissive. (Cat II impact)

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 -lL /etc/resolv.conf If the file mode is more permissive than 0644, this is a finding.

Fix Text

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