Stanford Whole Disk Encryption for Mac

Overview

When you run the Stanford Whole Disk Encryption (SWDE) installer, the first step is Stanford's Device Enrollment app, a brief questionnaire that gathers basic information about your computer. If you already have responded to these questions, your previous answers are displayed.

After you complete the questionnaire SWDE steps you through the process of encrypting your hard drive. The installer checks your computer to make sure certain requirements are met, such as having BigFix software installed. You will need to fix, or let the installer fix, any items that are flagged before continuing.

Once your computer has been authorized to install encryption, you are prompted to enable FileVault 2, Apple's built-in encryption technology, to encrypt the whole disk.

Notes:

  • Mac OS X 10.8 and above provide an interface to manage FileVault 2 that allows for the automation of storing recovery information for the encrypted drive. It's recommended that machines be upgraded to OS X 10.9 and above where possible.
  • For machines running  OS X 10.7 that already have FileVault 2 enabled, the SWDE installer prompts you to enter your recovery key.  If you did not record your recovery key when you enabled FileVault 2 you need to decrypt and re-encrypt to obtain a new one.  See the manual activation instructions for assistance with the process.
  • Boot Camp: FileVault 2 does not encrypt the Windows partition on systems running Boot Camp.  Therefore, SWDE-compliant machines cannot run Boot Camp.  OS X users needing to run Windows need to use VMware Fusion or Parallels.

Before you begin

IMPORTANT: Make sure that you back up your computer or data before you start encrypting. If the disk encryption process encounters a disk error, data loss or corruption could occur.

  • Before starting the encryption, make sure your computer is on AC power and has an active network connection.
  • Depending on the size and speed of your hard drive and how many files are stored there, encryption can take from 45 minutes to two days. You may want to install the the software at the end of the day and let the encryption run over night. You can use your computer during the encryption process, but certain activities may be noticeably slower.

Device enrollment questionnaire

  1. Run the installer. A setup wizard guides you through the steps necessary to install the software.
  2. As soon as the software is installed successfully, a questionnaire regarding the use of this computer for Stanford business launches. Click Proceed Now.

    start questionnaire  
  3. Next, choose whether or not you have a valid SUNet ID and then click Continue.

  4. If you have a valid SUNet ID:
    • Enter your SUNet ID and password on the WebLogin screen.

      WebLogin screen
    • You will be asked to answer some questions about this device and the types of data that is accessed and stored on it.
    • If BigFix, Stanford's patch management software, is not present on your computer, it will be installed for you.
  5. If you do not have a valid SUNet ID:
    • If you are no longer affiliated with Stanford, the questionnaire is terminated.
    • If  this computer is used for Stanford work, the questionnaire is terminated. Someone with a valid SUNet ID needs to complete the questionnaire.

Encrypt

After the questionnaire is completed, SWDE steps you through the process of encrypting your hard drive.

Run the encryption installer

After the questionnaire is completed, SWDE steps you through the process of encrypting your hard drive.

  1. The starting screen of the encryption process displays. If you are ready to encrypt your hard drive, check I have a backup and understand the risks involved and wish to continue and then click Continue. (If your computer is already encrypted this screen does not display.)

    acknowledge that you have a backup or understand the risk of not having one
  2. Next, select the Group and Sub-Group where this computer is located and then click OK.

  5. If your computer is running OS X 10.9.5 or higher and it was encrypted manually (not using SWDE):  the existing recovery key will be changed and the new key will be escrowed by BigFix.  You are prompted to log in with your administrator name and password and then your new encryption recovery key displays.
  6. The installer runs a test on your computer to ensure that certain requirements are met before encrypting. For example, anti-malware must be installed and some network services need to be disabled.
    • Click Fix Items to fix these problems.
    • Click Continue if the Test Results show that no items need to be fixed.
