What?

Learn about and experiment with various firewalls.

Why?

To be able to apply firewall evasion techniques, such as port hopping and port tunneling.

How?

• Firewall systems

• Evasion via controlling the source MAC/IP/Port

• Evasion via forcing fragmentation, MTU, and data length

• Evasion via modifying header fields

• Evasion using port hopping

• Evasion using port tunnelling

• Evasion using non-standard ports

• Next-Generation firewalls
