Solaris 10 SPARC STIG: GEN001362 (in versions v2 r4 through v1 r19)

Title

The /etc/resolv.conf file must be owned by root. (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

Verify the /etc/resolv.conf file is owned by root. Procedure: # ls -l /etc/resolv.conf If the file is not owned by root, this is a finding.

Fix Text

Change the owner of the /etc/resolv.conf file to root. # chown root /etc/resolv.conf
