During a blackbox pen test you attempt to pass IRC traffic over port 80/TCP from a compromised web enabled
host. The traffic gets blocked; however, outbound HTTP traffic is unimpeded.
What type of firewall is inspecting outbound traffic?

A.
Application

B.
Circuit

C.
Stateful

D.
Packet Filtering

Explanation:
An application firewall is an enhanced firewall that limits access by applications to the operating system (OS) of
a computer. Conventional firewalls merely control the flow of data to and from the central processing unit
(CPU), examining each packet and determining whether or not to forward it toward a particular destination. An
application firewall offers additional protection by controlling the execution of files or the handling of data by
specific applications.
