NSW Government uses Group Policy AppLocker to build an ‘unhackable’ Netbook

The NSW Department of Education and Training (DET) has come out and said that due to the new features in Windows 7 they were able to essentially build a computer to survive "the most hostile environment you can roll computers into".

image“DET also uses the AppLocker functionality within Windows 7 to dictate which applications can be installed on the device.”

AppLocker is a new feature with Windows 7 that allows IT administrators to lock down application to specific product and/or vendors with having to specific the specific version. This feature allows them to only allow a specific white list of application on the computers. This essentially prevents anyone from running any non-authorised code on the computer thus making it VERY difficult to prevent people hacking the computer with third-party tools or malware. What is really nice with this feature is that it does not stop computer from running applications after they have been updated with hot fixes and service packs as AppLocker works on the digital signature on the file and not a hash of the file itself. This makes the IT Administrators overhead far less as they no longer need to add every possible version of an application to the white list when they want it to work.

While DET does seem to have done a lot in securing the devices to the Nth degree I still reckon it wont take long for someone to find some hack or workaround. I think the itNews headline is just inviting trouble by calling it “Unhackable”. I call it the “If something is said to be “unhackable” then it is far from being secure” maximum. ( More info about Security Maximum’s can be found at http://whysecurityfails.com/maxims.html ). But don’t get me wrong I don’t think that this will be a flaw in the technology but more a security issue with them forgetting to lock down some or even leaking the default BIOS password.
