Throughout this chapter we identified a number of methods of creating multiple layers of a network architecture. We presented a challenge of when you face a router, and different firewalls as Bastion Hosts. Your challenge is as follows:
Carry out the process and methodology against the two firewalls, and add the
iptablesto your testing. Document what works and does not work and save it to you testing techniques fileAdd additional machines to the network, first test it and exploit it flat, then try and connect it to the different network devices.
Explore the options for adding reflexive ACLs to the router, and see if that prevents the penetration when a weak rule is in place. Explore and have fun and remember to document everything! There is a saying: "no job is complete until the documentation is delivered."
This challenge will allow you to practice the process against a number of devices, and more importantly, allow you to document methods that do or do not work to save...
