Essential Firewall Hardening Guide v.2
My self and a colleague put together a mandatory hardening guide for Network Firewalls for our company and with permission, we stripped out all references to the business and I now I'm making it available online. I was always looking for something like this and I know others could really use some guidelines, especially with compliance and auditing being so rampant lately.
I have two more to come soon - Network L3+ Router Hardening and Network L2 Switch Hardening (complete with Cisco how-to's for both IOS and CatOS).
Let me know what you think...
