SUMMARY

This step-by-step article describes how to configure Encrypting File System (EFS) to provide core file encryption technology when you store files on an NTFS file system partition. You can use EFS to encrypt and decrypt files to keep your files safe from intruders who might gain unauthorized physical access to your sensitive, stored data (for example, if your laptop or external disk drive is stolen).

How to Use EFS to Encrypt or Decrypt a Folder or a File

If you are using a remote server, you can encrypt files and folders on the server; however, your data is not protected if you access a file over the network. Windows 2000 provides network protocols such as Secure Sockets Layer/Private Communication Technology (SSL/PCT) to encrypt data access over the network.
