Name three types of firewalls __________, _______________, and _________________ (Choose three)

Packet filtering firewalls operate at the network layer and make decisions based on individual packet header information, such as source/destination IP addresses and port numbers, without inspecting packet contents or maintaining session state.

Application proxy firewalls (also known as gateway firewalls) operate at the application layer, acting as an intermediary between clients and servers, inspecting the content of traffic for specific applications and often providing advanced logging and security features.

Stateful inspection firewalls (or dynamic packet filtering firewalls) operate at the network and transport layers, examining traffic in the context of a connection, tracking the state of active connections, and allowing only legitimate return traffic to pass through.

Microsoft Proxy is a product name (e.g., Microsoft ISA Server, Forefront TMG), not a general firewall type based on operational methodology.

SonicWall is a brand or vendor of firewall devices and software, not a fundamental type of firewall technology.

Raptor Firewall was a specific firewall product (originally from Raptor Systems), not a generic classification of firewall technology.
