A network technician is installing a honeypot in the DMZ and wants to create a report of all the
UDP protocols that are being used. Which of the following firewalls can be used to track this?
A.
Dual homed
B.
Packet filtering
C.
Kernel proxy
D.
Stateful-inspection
stateful firewall (any firewall that performs stateful packet inspection (SPI) or stateful inspection) is a firewall that keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. The firewall is programmed to distinguish legitimate packets for different types of connections. Only packets matching a known active connection will be allowed by the firewall; others will be rejected.
