How to build a U-disk

U disk is very familiar with the storage equipment, U disk with seismic resistance, fast access, data storage security features, in the daily application of the very high rate of use. But for some companies that attach importance to information security, the U disk is a big threat to data leaks. Because the media of U disk is very flexible, can be made of watches and other unconventional shapes. can also through digital cameras, MP3 and other digital products to achieve, so using U disk can be very convenient to copy some important data. We can see some examples from Hollywood movies, in the first episode of the Spy mission, the secret agent will need to use a zip floppy to steal intelligence, but in the "Spy Sea", the theft of information began to use U disk. After the protagonist steals the intelligence, the guard at the door does not notice the data on the U disk (of course, in fact, it is due to the script rules).

The performance of the U disk in the movie let some unit leaders start to worry, these fans are also afraid of their own data by a small u disk God unnoticed to steal, so ordered the computer's USB interface with glue sealed up (this is not joking). In fact, we can not use such a violent means, as long as the computer to modify the registry, you can make u disk into a read-only equipment, that is, U disk data can only read, but can not write! This will not only avoid the data leakage caused by U disk, also can make U disk from virus attack

The following in an XP SP2 computer to show you how to achieve a read-only USB disk production, running on the computer regedit, we choose a new one under Hkey_local_machinesystemcurrentcontrolsetcontrol, The name of the item is storagedevicepolicies.

Under New Storagedevicepolicies, select a new DWORD value, and the name of the DWORD value is Writeprotect.

We set the value of Writeprotect to 1, so that the USB disk can only read operations, if the Writeprotect value set to 0,u disk can be normal read and write operation.

After setting up the registry, we will test, we are ready to send a folder to the U disk, try to see how the effect.

U disk display is written to protect, read-only u set is successful! In fact, if the operating system is Win7 or Win2008, we can also consider disabling the USB storage device through Group Policy, which would be more convenient to control.
