Security U disk setting method

Now U disk is more and more widely used, today teach you to use NTFS file permissions to create a secure u disk. The steps to create a secure USB flash drive using NTFS file management permissions are as follows: 1. First, create our U disk as a folder directory: system, work, TMP, important files are saved in the “Works” directory, only files can be added. Can not just delete: & rdquo; system & rdquo;, folder to save some fixed files, similar to the computer system level, can not be changed, can only read: Tmp save temporary files, can be manipulated at will. Then convert the U disk to the ntfs file system. There are many ways to do this. You can do this by running the "Converth:/fs:NTFS" command in the CMD. Second, right click on the "work" folder, select & rdquo; attributes & rarquo; security & rarr; advanced & rarr; permissions & rarr; edit & rdquo;, object name select Everyone, refuse to delete subfolders and files, delete, change permissions Take ownership of these 4 items and apply them to: only the folder, subfolders and files. Third, for the TMP directory, we don't have to worry about it. At this point, the basic security U disk settings are completed. If you add Aoutorun.inf and 3 folders with the same name exe file "read-only settings" on this basis, the operation is similar to the "system" folder, you can immunize the y disk virus to a certain extent. Finally, don't forget to enter the <quo;attrib+r+h+s”filename’” command on the command line to set read-only hidden and system properties for these four files to avoid being deleted innocently. 4. Set the fixed “System” folder to read-only. In the same property settings, in addition to traversing, listing, reading properties, reading extended property 4 read permissions, reject other permissions, and apply to the folder, subfolders and files, so that the entire directory There is only read-only permission.

U disk exchange of data between computers is very convenient, but if the U disk is infected with viruses or files are deleted accidentally, it is not good, create a secure U disk for different folders to set different permissions, you can securely protect U disk It is.
