FTester – Firewall Tester and IDS Testing tool

The New Acunetix V12 Engine


The Firewall Tester (FTester) is a tool designed for testing firewalls filtering policies and Intrusion Detection System (IDS) capabilities.

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.

Of course this is not an automated process, ftest.conf must be crafted for every different situation. Examples and rules are included in the attached configuration file.

The IDS (Intrusion Detection System) testing feature can be used either with ftest only or with the additional support of ftestd for handling stateful inspection IDS, ftest can also use common IDS evasion techniques. Instead of using the configuration syntax currently the script can also process snort rule definition file.

Features:

  • Firewall testing
  • IDS testing
  • Simulation of real TCP connections for stateful inspection firewalls and IDS
  • Connection spoofing
  • IP fragmentation / TCP segmentation
  • IDS evasion techniques

Requirements:

The following PERL modules are required: Net::RawIP, Net::PcapUtils, NetPacket

    more goodies

    nifty tool…. the ftester seems so easy… why didn’t I came up with the idea… there is basically a tool for sending data and a deamon to wait for the return value :)

    Kool package…
    the programmer has taken care of each and every bit… very easy to use and configure..

    The “READ ME” file is very helpful and has detailed information on configuring and using the tool.

    Great work…

    HIGHLY RECOMMENDED ;)

    yea it’s a great tool, it’s not that unique, probably the same result can be reached with nemesis, or on a smaller scale with hping

  5. Sandeep Nain July 26, 2007 at 5:58 am #

    Yeah I agree, its not unique but still very helpful and very easy to use with very good documentation..

  6. Darknet July 26, 2007 at 8:11 am #

    backbone: It can in a way, but then it’s a little more complex as you need to use something like hping to generate the packets, and something like wireshark to receive the packets, then you have to process them manually..tools this that come in two parts make the whole process a lot easier.

  7. backbone July 26, 2007 at 6:38 pm #

    yes Darknet, but hping(which also analyzes return packets)+wireshark(if needed) can give a slightly bigger number of advanced options that ftester ;)
