A Firewall:

Prevents authorized access to or from an Intranet.

Explanation:
this is the most correct answer because we use firewalls in networks where we need security, so
we secure our network from unauthorized, and with this we can control who can get in or get out of
it.
Incorrect Answers:
B: We don’t need firewalls in a unsecured network, we need them in networks that require
security.

C: We should not need to prevent authorized access, if it authorized, the traffic should go through.
D: We should not need to prevent authorized access, if it authorized, the traffic should go through.
E: A firewall is not a virus scanning engine, we have anti-virus for that matter, Firewalls are a form
of packet analyzers that says if traffics go through, is redirected or is discarded at one of its
interfaces, it doesn’t look for virus patterns.
