Please Note: There is a known incompatibility with Sophos and FileVault on Mac OS X 10.5.x. If you are using FileVault please do not install Sophos Antivirus at this time.
Prior to enabling FileVault the following considerations should be observed:
Although FileVault has a very low failure rate; it is recommended that users create a backup of documents and files prior to enabling FileVault. This backup will provide a means of recovery in the event that anything should happen.
- Time Machine:
Under normal operation Time Machine will backup information in the user's Home folder while the user is logged in. Once FileVault is enabled however, Time Machine will back up a user's Home folder only after the user logs out and recovery of individual files becomes difficult. It is for this reason that Time Machine's backup potential is reduced and is not recommended for use with FileVault. If an alternate backup solution is required, iBackup provides a freeware solution that allows on-demand and scheduled backup and recovery of individual files while you are logged in. http://www.apple.com/downloads/macosx/system_disk_utilities/ibackup.html
- Free Space:
When FileVault is enabled the user's Home folder is copied (not moved) to a protected space and the original is not deleted until the end of the process. This means that prior to enabling FileVault, the free space on the hard drive should be equal to or greater than the size of the Home folder. This free space requirement is also necessary in the event that FileVault is disabled. If you do not have this amount of free space available, then it may be necessary to offload some of the files in your home directory to an external device before beginning the process and then migrate the files over to the protected Home file once the process is complete.
- Open your System Preferences panel and click Security (circled in red below).
- On the General tab, select the items below to ensure maximum security.
- On the Firewall tab, select "Allow only essential services" to prevent unauthorized users from accessing your computer remotely.
- On the FileVault tab, click the button labeled "Set Master Password".
- On this screen you will set a Master Password that can unlock FileVault protected accounts. This is a feature that is designed to provide recovery for accounts. Set this password as something you won't forget, but ensure that it is different from your user account password. Do not lose or forget this password; this password cannot be recovered or reset once it is set.
- You will now be prompted for the password affiliated with your current user account.
- After your password is accepted you will be prompted to confirm that you want to turn on FileVault. On this screen, be sure to check the option to "Use secure erase". Once you click "Turn On FileVault" the computer will not be accessible for 1-2 hours depending on hardware.
NOTE: If your system is dual-boot or features a utility partition (recovery or Dell Media Direct) it is not compatible for PGP Whole Disk Encryption. If you have a Dell Inspiron M1210, Dell E5400 or Dell XPS please call AskIT at 205-996-5555 before attempting to encrypt your machine with PGP.
Please review the list of devices that are incompatible with PGP.
To successfully install and configure PGP, you will need the following:
- Administrative privileges
- An active connection to the Internet
- A physical keyboard - tablets without keyboards are unable to use the software
- One of the following operating systems: Windows 7, Windows Vista, XP Home or Professional 32-bit (SP2/SP3), XP Pro 64-bit (SP2), XP Tablet 2005, Windows 2000 (SP4)
- 512MB RAM
- 64MB hard disk space
Prepare Your Computer
- Back up your data - Prior to downloading or installing any encryption software such as PGP, be sure to back up your data to a trusted source. Devices such as external drives, CDs, DVDs and network drives are recommended for storage of important documents. it would also be a good idea to ensure that your have the ability to reinstall any important software if any data loss should actually occur.
- Defragment - Prior to encryption, you may wish to defragment your computer to speed up the encryption process. To do so, click the Start menu. Point to Programs>Accessories>System Tools, and then click Disk Defragmenter. Click the Analyze button; a report will appear telling you whether or not defragmentation is recommended. If it is, click the Defragment button to begin; if not, close Disk Defragmenter and proceed to the next step.
- Check the disk for disk errors - Under normal operation, many hard drives do not exhibit any signs of corruption or flaws, but when the data on the drive is encrypted, those issues can present a greater problem leading to file corruption, and in some cases complete loss of the operating system. In order to identify and correct these issues before any loss is incurred, SpinRite was purchased for the campus and is available on the IT Software Library site for faculty and staff. The software will assist you in creating a bootable CD that will scan and correct any disk errors. This step is optional, but is also highly recommended.
- Check power and network connections - Before installing, be sure your computer is plugged into a wall outlet and has an active network connection.
Download and Install PGP Software
- Go to the UAB Software Library, located at www.uab.edu/it/software. Locate the appropriate PGP software and click to begin downloading.
- Prior to installation, be sure to close all running programs and save anything you are working on.
- Navigate to where you saved the software and launch the PGP installer. In the PGP Desktop window, select English.
- Read the licensing agreement, select "I Accept" the licensing agreement, and click Next.
- Click Nextagain.
- The installer will start copying files into place.
- Click Yes to reboot. When the computer has rebooted and you log in, the PGP Setup Assistant should automatically appear.
- When prompted for domain credentials, enter your BlazerID and password.
- Select "I am a new user", and click Next.
- Click Next.
- The next box to pop up will be a prompt to create a passphrase user. Enter the username and password you use to log into your system. In many areas of campus, this is also your BlazerID and password with a domain of UAB.
- The program should begin to automatically encrypt the disk in the background while you go about your normal work. Note: Encryption may take up to eight hours. If necessary, you can shut down the computer (Start>Shutdown>Turn off computer), but DO NOT abruptly power off the system.
- When the encryption of the boot drive is complete, the lower icon will become a solid padlock.
- From this point on, prior to booting Windows, you will receive a gray PGP boot screen in which you are prompted to enter the passphrase that you entered during setup. Entering a correct passphrase permits access to the machine and will log you into the Windows operating system through the single sign-on feature.
Although rare, situations have occurred where a hard drive encrypted with PGP does not boot. To assist in recovery of these drives, the creation and use of a PGP Boot Disk is highly recommended.
Please note that each version of PGP requires a boot disk unique to the particular version in use on the client. For example, if you attempt to use a 9.6 recovery disk to decrypt a disk protected with PGP Whole Disk Encryption 9.9 software, any data on the PGP Whole Disk Encrypted 9.9 disk will be unrecoverable.
Note: If you do not remember the recovery passphrase, please contact the help desk, AskIT, by email AskIT@uab.edu, or by phone, 205-996-5555.
Create a Recovery Boot Disk
- Download the appropriate ISO file from the Symantec archives:
a) Version 10.x: http://www.symantec.com/business/support/index?page=content&id=TECH152604
b) Version 9.X: http://www.symantec.com/business/support/index?page=content&id=TECH148915
- Burn the ISO to a CD, label it appropriately and store it in a safe place.
Using a Recovery Boot Disk
- Insert your Recovery CD into the computer's CD drive.
- Reboot the computer and boot to the CD.
- When the login screen appears, enter the recovery passphrase for the encrypted drive and press Enter to begin decryption. This operation can take many hours and the system should not be powered off.
- Once the process is complete, the system should start as normal. If the operating system still does not boot, proceed with your operating system repair or data migration process.
Using a Recovery Workstation
If you have the resources or equipment available, the hard drive from the system that will not boot can be accessed by a workstation that has PGP installed on it. Simply connect the device using a USB hard drive bay or adapter, and enter a passphrase associated with the drive. Once the hard drive is mounted to the recovery system, files can be recovered by moving them or by decrypting the hard drive.
If you experience any issues with PGP, please report them to the help desk, AskIT, by email at AskIT@uab.edu, or by phone at 205-996-5555. Please be sure to provide the following information:
- Error messages
- Computer make and model
- Internet connection type
- PGP installer version
- Estimated time of occurrence (if possible)
Common Solutions to Installation Issues
- Verify that you are an administrator of the system on which you are attempting to install PGP.
- Open your web browser and ensure that you have Internet connectivity by opening a website.
- Be sure that you have a current installation package for PGP Desktop. Visit www.uab.edu/it/software for the latest installation files.
- Ensure that you are using your BlazerID and strong password for the PGP Enrollment credentials.
Common Solutions to Password Related Issues
- Verify that Caps Lock is not on while authenticating.
- If you recently changed your account password, you may have to provide the old password until you log in to the system with your new password.
- If the previously mentioned steps do not resolve your issue, you should call the AskIT Help Desk to request a PGP recovery token for the system or portable device. A recovery token is a one-time password that will allow you to bypass PGP, but it will not bypass the operating system password; you are still required to log in.
Common Solutions to Boot/Startup Related Issues
- Ensure that a keyboard is connected to the system. Systems such as tablets without physical keyboards will not be able to authenticate on the PGP boot screen.
- Remove any CDs, DVDs or USB drives from the system. Many of these devices have features that allow them to start before the system hard drive.
- Does the system have multiple operating systems or Dell Media Direct? If so, then you will need to contact your support personnel to assist you with the recovery of your hard drive. Please note that PGP should never be installed on systems with multiple operating systems, as it will render the system inoperable.
- See the PGP Recovery documentation for further support.
