Windows Embedded Firewall Configuration (Prevent LAN Snooping)

  • DNS Benchmark v2 Release 5 with Consultant License
    Guest:
    If you own any earlier release of our DNS Benchmark you may immediately download its release #5 replacement. Running an earlier release will detect the new release and help you upgrade.

    Although this release is cosmetic, appearance matters and affects ease of use. The biggest change, as seen in the image above, is that the DNS Benchmark now has a traditional Windows application menu to more fully expose its many features. This release is also "Consultant License Aware" and GRC will now issue a Consultant version when owners have previously purchased four "Personal Use" licenses. If you have previously purchased four DNSB licenses, or if you wish to upgrade your "Personal Use" license to Consultant, GRC's purchase process will direct you through that process.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

Remember Kerio from the Windows XP days?
Used to use that in manual config mode to *very* closely taylor OUTBOUND traffic on my system.

Well, ever since we lost that, have been using the Windows Embedded firewall.
It's not as smart as Kerio since it only validates by path, rather than binary signature, but it's better than nothing.

Anyway, in past SecurityNOW! shows, it became apparent that concerns were growing over LAN snooping by scripts running on websites.

Outbound firewall on, this is how you prevent that.

I do this for all of my web browsers also...

Plenty of other options to be aware of also...

If you have any experience with firewalls that were like the ancient Kerio product, (but updated with modern features of course,) let me know.

To view the Windows Firewall Logging...

Elevated Command Prompt:
Code: 
start "PFirewall.Log" tail -f %systemroot%\system32\logfiles\firewall\pfirewall.log


You have limited ability to customize the logging from the "WF.MSC" utility.

The Embedded Windows Firewall logging by the way doesn't tie traffic to a specific process; so must rely on some other tools, including ProcMon, TCPView, and/or looping "NetStat -ANO" to do that.

ProcMon Rulebase here...

If you don't like those extra lines, try using the code tag instead of the icode (inline code) tag. :unsure:
