Advanced tasks Managing Drive Encryption (administrator task) The Drive Encryption window allows Windows administrators to view and change the status of Drive Encryption (active or inactive) and to view the encryption status of all of the hard drives on the computer. Activating a TPM-protected password Use Embedded Security for HP ProtectTools to activate the TPM. After activation, logging in at the Drive Encryption logon screen requires the Windows user name and password. NOTE: Because the password is protected by a TPM security chip, if the hard drive is moved to another computer, data cannot be accessed unless the TPM settings are migrated to that computer. 1. Use Embedded Security for HP ProtectTools to activate the TPM. 2. In the Administrative Console left pane, expand Drive Encryption, and click Encryption Management. 3. Select the Enhance security with TPM check box. Encrypting or decrypting individual drives 1. In the Administrative Console left pane, expand Drive Encryption, and click Encryption Management. 2. Click the Change Encryption button. 3. In the Change Encryption dialog box, select or clear the check box next to each hard drive you want to encrypt or decrypt, and then click OK. NOTE: When the drive is being encrypted or decrypted, the progress bar shows the time remaining to complete the process during the current session. If the computer is shut down or initiates Sleep or Hibernation during the encryption process and then restarts, the Time Remaining display resets to the beginning, but the actual encryption resumes where it last stopped. The time remaining and progress display will change more quickly to reflect the previous progress. Backup and recovery (administrator task) The Drive Encryption: Backup and Recovery window allows Windows administrators to back up and recover encryption keys. Creating backup keys CAUTION: Be sure to keep the storage device containing the backup key in a safe place, because if you forget your password or lose your Java Card, this device provides your only access to your hard drive. 1. In the Administrative Console left pane, expand Drive Encryption, and click Backup and Recovery. 2. Click the Backup Keys button. 3. On the "Select Backup Disk" page, click the name of the device where you want to back up your encryption key, and then click Next. 28 Chapter 5 Drive Encryption for HP ProtectTools ENWW
