For those who are interested:

BFE is key component of Windows Vista/7 Filtering Platform. Microsoft forces firewall vendors to use it. Some critical information can be retreived via WFP/BFE only.

JPF uses WFP functions for application layer filtering and if you stop BFE the application layer will be turned off.

Some firewalls simply mark their component as dependent from BFE service and don't start at all when BFE is turned off.

JPF's network and process attack layers can work without BFE and so JPF is not stopped when BFE is inactive.

There are no specific notifications about a turned of BFE service because JPF can control an access to the Service Control Manager. It produces and processes the "access to system services" event.

JPF and Windows 7 BFE
« Reply #1 on: December 22, 2009, 12:43:12 AM »
Hi,
just found out that JPF 2.1.x.x silently stops filtering correctly on my Windows 7 (Enterprise EN 32 Bit build 7600) when I stop the Windows Base Filtering Engine service.

JPF keeps running but the "Applications" tab sheet is empty and no applications are filtered anymore.

Don't know if anyone else can confirm this for his system, too ?!

Regards
