Difference between signed and unsigned
Would anyone of us help me in understanding the difference between signed and unsigned drivers.
A signed driver is basically a digitally signed driver, which means that the driver software is associated with a digital certificate that allows identification of the publisher of the driver. It also ensures that the driver has never been modified by anyone else, as that would corrupt the signed status and make it unsigned.
So using a signed driver will ensure that Windows can automatically install the driver and prevents malicious software to be installed along with the driver. Considering that drivers operate at a very high security level in the operating system, it is very important to use safe drivers.
Windows Vista, Windows 2008 server and Windows 7 already enforce unsigned drivers to be installed using administrator level access, but how can you know for sure that an unsigned driver is safe?
Well, you cannot really. So always make sure that your security software is up to date and active, and make a backup or create a system restore point before you make any changes to your system, especially when installing device drivers.
so that the conversation will remain readable.
