Answer 2

Answer:

Correct option A. Packet Filtering Firewall

Packet Filtering Firewall are the types of firewall.

Explanation:

The oldest and most basic type of firewall is a packet filtering firewall. They check a data packet's source IP and destination IP, protocol, source port, and destination port against predefined rules at the network layer to determine whether to pass or discard it. Based on how they work and what they look like, there are four different types of firewalls. Packet Filtering Firewalls, Circuit Level Gateway Firewalls, Application Level Gateway Firewalls, and Stately Multilayer Inspection Firewalls are the types of firewalls available.

Firewalls that are based on hardware: A hardware-based firewall is a device that serves as a secure gateway between devices inside and outside the network perimeter.

Firewalls that are based on software: A software-based firewall, also known as a host firewall, is a firewall that runs on a server or other device.

The following are five different types of firewalls:

1. Packet filtering firewall.
2. Circuit-level gateway.
3. Application-level gateway (aka proxy firewall).
4. Stateful inspection firewall.
5. Next-generation firewall (NGFW).
