Consider the protection offered by the password for backed-up keys. The keys do not have to be imported back to the original account for which they are issued. They can be imported into any account if the password used to export the keys is known. If the password is weak or stored with the backed-up keys, the keys might easily be used in a successful attack on EFS. Consider the safety of keys that have been backed up. Backed-up keys can also be damaged or lost. Just as you should verify data backups, you should also verify backed-up encryption keys by importing them into an account. However, providing all users with an additional account to do so is impractical and might prove to be a security liability, as users might forget to delete the account profile or otherwise remove the encryption keys and thus provide another account that can access their files. Consider removing file recovery agent keys from the network. If file recovery agent keys are stored in the owner s profile, the owner can read files that were encrypted when the keys were available. This access is transparent. Although access can be audited, the recovery agent has already read the file. If the recovery agent private key is backed up and removed from the network, the file recovery agent cannot transparently read the file. She must import the key and then read the file.

File recovery can be a management nightmare and an iffy situation when self-signed certificates are used. One solution is the development of a PKI to manage EFS. Before doing so, consider the following:

Consider the PKI design. If no PKI exists, a considerable investment in time must be spent planning the PKI and the use of the PKI to deploy EFS certificates. Consider CA security. The security of the EFS encrypted files is dependent on the security of the CA that issues the EFS certificates and EFS recovery agent cer tificates. This server should be secured. Consider EFS key backup. Establishing a PKI for the management of EFS cer tificates does not automatically provide EFS key backup. You still should back up critical EFS keys such as those issued to file recovery agents. Consider file recovery agents. You can create as many file recovery agents as you want. It might be appropriate to create file recovery agent accounts for spe cific OUs. This can split the responsibility and provide tighter control over EFS encrypted files.

Consider the file recovery process. The process of file recovery must be designed, including designating file recovery agents and outlining the process for file recovery. Best practices include:

Keeping the file recovery agent private keys off-line. The public keys are needed in the encryption process. The private key is needed only for recovery. Providing off-line recovery stations. Encrypted files are moved to these sta tions for recovery. The file recovery agent keys are imported into an account on the workstation and used to decrypt the files. Decrypted files are then safely moved to the owner s computer. The file recovery agent keys are then exported and removed from the file recovery station.
Considerations for Designing Key Recovery for EFS
A Windows Server 2003 Enterprise Edition computer with the certificate services can be configured to issue EFS certificates with a file archival property. When properly imple mented, the EFS keys are archived at the CA and can be recovered as necessary. This implementation was described in 2.
How to Disable EFS
If your EFS policy is not to use it, or if you want to ensure recovery of EFS files and need time to design and deploy a solution, you should disable EFS. There is a risk with any technology. By default, EFS is available to anyone with a user account. Without proper training and a file recovery process in place, the information in EFS files can be lost. This is because the EFS keys required to decrypt the file can be lost or damaged. If the EFS keys are not present and undamaged, EFS encrypted files cannot be read. EFS is disabled by clearing the Allow Users To Encrypt Files Using Encrypting File Sys tem (EFS) check box. Figure 9-25 shows the check box. This check box is located on the Properties page for the Encrypting File System policy in the GPO. The local Secu rity Policy can be used to disable EFS on a single system, while the domain GPO can be used to disable EFS for the domain. This option is available by opening the GPO and navigating to the Security Settings area of the GPO. Right-click the Encrypting File System policy, and select properties to locate this option. In Windows 2000, EFS could be disabled simply by deleting all recovery agents. This method will not work in Win dows XP or Windows Server 2003, as both allow EFS to not have a recovery agent.
