A circuit level gateway is ________ when compared to an application level firewall.
A.
Easier to maintain.
B.
More difficult to maintain.
C.
More secure.
D.
Slower
Explanation:
Since circuit level gateways are not as high in the OSI model for the inspection as Application level
firewalls, they are easier to maintain and configure. Application layer firewalls are up to layer 7 of
the OSI model and provide a great bunch of options and complex configurations. Application layer
firewalls are more secure than circuit level gateway because they can track and analyze information
up to layer 7, a drawback to this, is that this functionality makes them slower.
