Enhance Network Security With Fwbuilder On Linux Systems

Fwbuilder is a unique graphical firewall tool that allows the user to create objects and then drag and drop those objects into firewalls, to build a powerful security system for a single PC or a network of PCs. Fwbuilder supports a wide range of firewalls (Cisco ASA/PIX, Linux iptables, FreeBSD's ipfilter, OpenBSD's pf, and more), so its rules can be deployed on multiple platforms. . Let's take a look at using Fwbuilder on Linux, which might just become a life-long affair with a powerful security system. Installation of Fwbuilder is as simple as searching for "fwbuilder" (no quotes) in your Add/Remove Software tool (such as Package-Kit, Synaptic, etc) and marking Fwbuilder for installation. However, if you're installing Fwbuilder on Ubuntu, the package that will install is out of date and will not work. In order to get a working, updated Fwbuilder installed on Ubuntu, follow these steps (You will either have to su to the root user or use sudo for this to work): The link for this article located at Linux.com is no longer available. . Delve into the capabilities of Fwbuilder for crafting resilient firewalls on Linux while simplifying network protection protocols effortlessly..

Testing Your Linux Firewall Effectively with FTester Utility

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! . The tool consists of two perl scripts, a packet injector (ftest) and the listening sniffer (ftestd). The first script injects custom packets, defined in ftest.conf, with a signature in the data part while the sniffer listens for such marked packets. The scripts both write a log file which is in the same form for both scripts. A diff of the two produced files (ftest.log and ftestd.log) shows the packets that were unable to reach the sniffer due to filtering rules if these two scripts are ran on hosts placed on two different sides of a firewall. Stateful inspection firewalls are handled with the 'connection spoofing' option. A script called freport is also available for automatically parse the log files. The link for this article located at How To Forge is no longer available. . Enhance your Linux firewall's effectiveness with FTester by following key steps: install, configure, run tests, interpret results, adjust rules, monitor, and document.
