Windows XP SP2 new features: U disk can not take away the secret

Today, portable storage devices (USB KEY, flash drive, music player ...) has become a real threat to corporate information security, such a small device, but can It is convenient to instantly copy a large amount of important data from the enterprise computer or send the virus to the enterprise LAN. In today's Windows systems, we can easily plug in portable storage devices and copy files to each other. In fact, for many business managers, this is really "convenient" too much.

said that in the next version of Longhorn Windows, companies will be able to prohibit the use of the above equipment off employees in the computer.

Market research firm Gartner recommends that big companies add security to plug-and-play functionality in existing PCs before the release of Longhorn in 2006. After all, no one knows if Microsoft can release Longhorn in 2006 on time (according to Microsoft's previous bad record, the possibility of publishing on time is quite small). Moreover, from the release to the large-scale deployment of enterprises, it will take a long time. And in such a long wait, are we just watching the data leaking?

not, and now the application software can certainly find a solution to this problem, but in fact, Microsoft has brought a simple solution for us in the new release of Windows SP2 in:

1 Click Start Menu->Run->Enter regedit to open the Registry Editor

2 Locate the HKLM\\System\\CurrentControlSet\\Control\\StorageDevicePolicIEs project

3 Add a file called WriteProtect Key value of DWord type

4 Assign 1 to this value

5 Exit the registry

(Recommended to back up the registry information before modification)

This operation allows the USB device connected to this computer to be set to read-only.

If the key value is set to 0, the read-only limit of the USB device will be canceled.

look at it, the improvement seems to SP2 can see that Microsoft is hard at safety performance under a lot of effort.
