As we all know, not everyone is fortunate enough to have a blank cheque
for security-related procurement and implementation. Making the best of
your allocated budget may at times call for primary or supplementary
solutions that are freely available. This strategy cuts procurement time
completely out of the loop as well. Here's a list of security tools
available on the Web for free that you should add to your toolbox.
BartPE: Preinstalled Environment Troubled by that incessant spyware or
virus that just doesn't seem to go away? Need a way to troubleshoot a
system without booting the operating system installed on it? BartPE and
the right plug-ins will let you do this. www.nu2.nu/pebuilder
Snort: Open Source Intrusion Detection System Arguably the world's most
used Intrusion Detection System. Both Windows and Linux binaries are
VMWare Server: A virtual environment It finally happened: VMWare is
available for free. Patch management, QA, vulnerability remediation
testing and other daily activities are now available without a
significant capital investment. VMWare also offers images of various
environments, configurations and operating systems available for
download (they're called "appliances") and ready to use in conjunction
with the main product. Just download, point VMWare to the image and test
DataRescue's IDA Pro Freeware 4.3 disassembler and debugger Although not
posted on the DataRescue site any more, the free version of their
utility will turn up with a quick Google dig. Try
OllyDbg disassembler and debugger Probably the world's most used
debugger disassembler. Gives most commercial debuggers a good run for
their money. www.ollydbg.de
eEye Digital Security's Binary Diffing Suite A good, free suite of
binary diffing tools you can use to see the effect that a released patch
may have on your environment. Read the Web site, as there are some
platform dependencies. research.eeye.com/html/tools/RT20060801-1.html
Cygwin: Linux-like environment for Windows Need to run some scripts or
programs that previously ran only under Linux? Do you miss your Linux
command line when running Windows? www.cygwin.com
Nagios: An open-source host, service and network monitoring program Not
for security only, but Nagios can be used to monitor for events that
typically have security implications. This is one that both the CIO and
CISO will agree upon. www.nagios.org iptables and Firewall Builder:
Firewall and Management Interface Don't have the deep pockets for a
Checkpoint, Cisco or Juniper? iptables comes with most Linux
distributions. Not comfortable using a command line to manage it?
Firewall Builder is an intuitive way to install and manage the rule set.
Get a couple of credit card CDs, create a bootable distribution, and
you've got a firewall in your pocket. www.iptables.org and
Apache SpamAssassin: Fight Spam at the Gateway Not really a secret to
most people. With the right configuration this is difficult to beat no
matter how much you spend on an antispam solution.
OpenSSH for Windows: Secure Shell for Windows Because FTP is so passe
(and insecure), use OpenSSH on the server side coupled with "PuTTY" and
WinSCP on the client side for a cheap way to secure your file transfers.
Cheops-ng: "The Network Swiss Army Knife" A tool for mapping and
monitoring your network. This is an excellent free way to track down
most of the systems on your network.
ACID (Analysis Console for Intrusion Databases) An analysis engine to
search and process security events generated by various intrusion
detection systems, firewalls and network monitoring tools.
