Encrypting files offline

For Windows 2000 has been possible autonomous cache files (also known as the cache on the client side). For this purpose, the technology of managing Microsoft IntelliMirror ™, which gives users the opportunity to work with the files located in file shares, even at a time when the client computers disconnected from the network.

For example, when mobile users viewing public folders on the computer, disconnected from the network, they may see, read and edit files because these files were keshirovany on their client computers. When mobile users connect to the server at a later date, the system produces alignment changed files with files stored on the server.

In Windows XP client is now capable of autonomous encryption of files and folders using EFS encrypted file system. This is especially attractive to traveling professionals who regularly required to work without the network, while ensuring the security of data.

All files are stored on a local computer in a common database, which also limits access to these files through access control tables defined explicitly. The database displays the files to the user in such a way that the structure and format of the database remain hidden and the user is dealing with the usual folder. Files and folders other users are shown, and there is no access to them. If autonomous encrypted files, the entire database is encrypted using EFS certificate for a computer. Selecting individual files and folders for decryption is not met. Thus, if this option is used, then the entire database offline files by default protected from attacks with the use of its own system EFS. However, encrypted database files autonomous there is one limitation: the user when working offline its files and folders will not appear alternate color. When working online, a remote server can selectively apply the encryption of files and folders, so that the mapping of encrypted files while working in interactive and standalone modes may seem contradictory user.
