PCCET: Understanding Network Traffic Filtering Based on Source and Destination IP Address

Learn about the differences between stateless and stateful firewalls. Understand how stateless firewalls filter traffic based on IP addresses.

Question

Which network firewall primarily filters traffic based on source and destination IP address?

A. Proxy
B. Stateful
C. Stateless
D. Application

Answer

C. Stateless

Explanation

Stateless firewalls primarily filter traffic based on source and destination IP addresses. They do not keep track of the state of network connections but instead, they filter packets independently. This is in contrast to stateful firewalls (option B) which monitor the state of active connections and use this information to determine which network packets to allow through.
