Types of Firewalls
- we learned about different types of firewalls which are essential tools in securing networks. A firewall acts as a barrier between internal networks and untrusted external networks like the Internet.
| Type of Firewall | Operating Layer | Key Features |
|---|---|---|
| Packet-Filtering Firewall | Network Layer | Fast, examines packet headers |
| Stateful Inspection Firewall | Transport Layer | Tracks state of connections |
| Proxy Firewall | Application Layer | Intermediary, better anonymity and trafficfiltering |
