Hey,

I get this question a lot: how can we block U3 devices on the network?

Well, one approach that some companies take is to simply block the physical USB ports by glue etc. - no USB devices are able to get in, so we have a “secure” system… Hmmm, this would mean that we are not able to use other USB devices either - maybe not the best solution for all of us then…

If you have Windows Vista deployed the new Device Control functionality, but most companies have Windows XP and Windows Server 2003 products in production (and probably waits for Vista Service Pack 1 before they go ahead with the Vista deployment)… So, what could they do then?

Third party software, like GFI EndPointSecurity is capable of blocking USB devices etc. - and it’s does a very good job too, but there’s also a free way to do it (if you ask me it’s the best way to do it): implement Software Restriction Policies (SRP)!

I’ve been writing about the “Default Deny All Applications” approach and this is (of couse) also capable of blocking U3 devices - out…
