Types of Firewalls

Packet-Filtering Firewall

  • Checks packets for source/destination IP, port, and protocol.
  • Lightweight but limited context awareness.

Stateful Inspection Firewall

  • Monitors state of active connections.
  • Makes decisions based on connection context.

Proxy Firewall

  • Intercepts traffic between client and server.
  • Can filter at application layer.

Next-Generation Firewall (NGFW)

  • Combines traditional firewall with features like IPS, deep packet inspection, application control.
