Of the following choices, which one is a type of firewall actively maintaining awareness of the status conversations between internal and external hosts? Explain. A) Stateful Firewall.
B) Non-Passive Firewall.
C) Active State Firewall.
D) Stateless Firewall.
E) None of the above

A) Stateful Firewall.

Explanation:

A stateful firewall actively inspects the conditions and integrity of active connections. It is always in an active and standby mode to holistically evaluate the conditions of active network conditions.

Network traffics that pass their evaluation can have access to the protected network whereas traffics that do not pass their evaluation are blocked. A disadvantage of this firewall is that it can slow the activity of the local network because of all the monitoring it has to perform.

The correct answer is A)

Explanation:

A firewall in the computer science parlance refers to a program that is designed specifically to monitor the inflow and outflow of connectivity traffic. By a predetermined set of rules, it is able to block unwanted connections, suspicious and or malicious connections thus preventing the computer from external attack.

As indicated in the question, there are various types of firewalls.

A Stateful Firewall is one that checks the complete state of network connections. This includes all communication between all incoming connections and internal protocol. So all incoming traffic is first screened and if they demonstrate any semblance of a malicious program or traffic, they are terminated at source.
