Re: Why are there no USB Firewalls yet?

The USB-IF spokesperson added that USB specifications support additional security, but equipment makers decide whether to implement these capabilities, which would entail greater cost.  


Seems that security and cost will be added following some high profile breach. But, still that would be the security added at USB owners end rather than the device which will run it.

USBs and the military / intelligence world
The Department of Defense tried imposing an absolute ban on USB removable storage a few years ago but eventually wound up allowing exceptions selectively. USBs were apparently a factor in the Edward Snowden leak scandal as well. One challenge: USB has become the standard interface for connecting all sorts of gadgets to a PC, including keyboard and mouse. Maintaining an absolute ban might make a lot of sense -- except that it's impossible to maintain.

Re: Why are there no USB Firewalls yet?
Amazed that still the USB culture prevails in many organizations where numerous flash drives from Employees, Customers, Vendors and even the visitors and trainees find their way into company PCs. From the article, it seems that currently the only way to cover this risk is to restrict thumb drive use. I wonder how culture can be changed quickly and are there any secure alternatives available.

Re: Why are there no USB Firewalls yet?
I wonder what percentage of people insert thumb drives they find somewhere? Just leaving compromised USB sticks in hotels and in bars is probably a very efficient way to create a botnet.

I was reading the Blogpost and Wondering to myself.

Why are their no USB Firewalls yet?

Seems to be a matter of Cost primarily.

The other issue is that if they can hit the BiOS with their attacks ,absolutely anything is possible.

And Hardware Level attacks are much more difficult to erase than just pure Software Hacks.

Lot of Trouble,Looking forwads to this Black Hat Presentation.
