Good question. There's actually alot to security. Types of firewalls, security protocols, encryption. Here's a little.

Layer 3: Packet Filtering Firewalls, IPSec
Layer 4: Circuit Level Firewalls
Layer 6: Encryption
Layer 7: Application Proxy Firewalls
Layer 3-7: Stateful Inspection Firewalls

I wrote a whitepaper on firewalls (remove spaces from URL).
