Recently, I wrote an article about "How to scan your Linux-Distro for Root Kits". Now that the machine is... clean! I think, a good thing TO-DO, is to test my Firewall (AGAIN!) The good news are that we can use the free tool FTester. The bad news are that FTester needs to be configured right...So...Let's get to work!

Firewall Migration

When birds migrate, they expend a huge amount of energy winging their way from one place to another, depending on sheer endurance to complete the journey safely. And so, it seems, it goes with with security managers faced with swapping out their gateway firewalls. Firewall migration for mid- to large-sized enterprises in particular appears to be a lengthy project indeed when organizations migrate from one vendor's firewall to another since by all accounts, firewall product design differs substantially. Our story this week looks at the topic.

All-in-one Linux Firewall touts ease of use, advanced features

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

If you haven't checked out Endian Firewall yet, download the code and give it a try. Endian Firewall is a packaged Linux security distribution that combines several open source firewall, VPN and anti-virus packages with a hardened Linux operating system. There are many Linux security appliance packages out there, so Endian is hoping to differentiate its distribution with ease-of-use management and set-up features. According to the developers' Web site, the "turn-key" package was created with "usability in mind ... without losing its flexibility." A set of browser-based wizards is used for setup, configuration and maintenance, and the software can be installed via the RPM package manager standard.

Roll Your Own Firewall

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Over the years I have learned how to roll my own firewall script and call it from /etc directory. Of course, my firewall is only INPUT based, instead of INPUT and OUTPUT based, but I find that building an INPUT/OUTPUT based firewall is tremendously difficult and not really all that necessary if you use good download practices on your Linux server or PC and/or if you're already behind a NAT router (such as a home-based DSL or cable router or wireless router) or other firewall.
