The document discusses various types of firewalls including packet filtering, stateful/stateless inspection, next-generation firewalls (NGFW), application firewalls, and proxy firewalls. Each type serves a distinct purpose in network security, with some focusing on basic packet analysis while others provide deeper inspection of applications and user transactions. Understanding these differences is crucial for effectively protecting networks against cyber threats.

1. Compare and contrast the different firewall types and explain
their importance (Packet filtering, stateful/ stateless inspection,
NGFW/Layer 7, Network Based, application, and proxy
firewalls).
