Answer: A
Routers programmed with outbound traffic filtering, drop
outbound packets that contain addresses from other than the
user's organization, including source addresses that can not
be routed. Broadcast blocking can be done by filtering
routers or firewalls. When programmed, IP packets coming
from the Internet and using an address that broadcasts to
every computer on the destination organization's network can
be dropped. Firewalls and filtering routers can be
programmed to limit services not allowed by policy and can
help prevent use of the company's systems. However, this
will not isolate packets that can not be routed. Network
performance monitoring is a way to monitor system
performance for potential intrusions on a real-time basis
and could help identify unusual traffic volumes.
