The PRIMARY objective of a firewall is to protect:
A. internal systems from exploitation by external threats.
B. external systems from exploitation by internal threats.
C. internal systems from exploitation by internal threats.
D. itself and attached systems against being used to attack
other systems.
Answer / guest
Answer: A
Firewall is placed at the point where the internal network
connects to the outside world I.e., Internet. It acts as a
security guard to the network, protecting it against
malicious attacks from outside the organization?s network.
It screens packets coming into and going out of the internal
network and prevents malicious packets from entering it and
denies access to prohibited resources on the Internet for
the internal users. It is neither the responsibility nor is
it possible for the organization to protect outside systems.
Packets whose source and destination IP addresses refer to
hosts within the same network are not sent out of the
network and hence do not pose a security threat. Choice D is
not a primary objective as this is just one form of attack
hackers resort to that the firewall protects the internal
network form.
