A.
Firewalls should provide network-level protection, by inspecting packets all layers of the OSI
model.

B.
Firewall should not inspect traffic below the Application Layer of the OSI model, because such
inspection is no longer relevant.

C.
Firewalls should understand application behavior, to protect against application attacks and
hazards.

D.
Firewalls should provide separate proxy processes for each application accessed through the
firewall.

E.
Firewalls should be installed on all Web servers, behind organizations’ intranet.
