If a system has no default gateway defined, the system is at increased risk of man-in-the-middle, monitoring, and Denial of Service attacks.

Check the system for an IPv4 default route
Procedure:
# netstat -r |grep default

If a default route is not defined, this is a finding.

Set a default gateway for IPv4.
