This also helps safeguarding the data in the event the device is misplaced or lost and also ensures that the data can be recovered in the event that the user forgets the password. An encrypted disk prevents unauthorized access to the data and documents on the disk and ensures that a password is required to boot into the disk before the data can be accessible. Step 3: Configure FileVault in the macOS Device ProfileįileVault allows IT Admins to leverage the macOS built-in Full Disk Encryption program and encrypt the disk.Step 2: Generating an Institutional Recovery Key.
I recommend performing routine incremental local backups cloud-based backups using software and services that allow control of encryption with keys or passphrases you specify. The backups should be encrypted, as well, but again using different means. I know this last paragraph might sound like “I told you so,” but you should always have complete backups-preferably two different kinds-of all your data, especially data on encrypted drives that are effectively impossible to recover. Software Macworld awarded 4 1/2 mice to last October, notes that it only has the potential to recover an encrypted drive if you can mount a partition so that it can scan the file system. Now, as for recovering a FileVault-encrypted drive that’s been reformatted so that you could, say, use a recovery key, the odds seem to be me about zero. Apple employs a very strong encryption algorithm that stands no chance at being broken in the lifetime of our planet at current estimates, even by an owner who has full rights for everything on the drive. If you don’t store it there, and you can’t find the recovery key nor can you log in through the startup process, the data is truly gone forever. You can opt to store the recovery key in iCloud protected with your iCloud account password. and you can opt to store it in iCloud.Ĭreates a recovery key for your startup disk that you can use as a last resort, such as forgetting all the passwords for all the authorized accounts, or conceivably if the Recovery Disk partition were damaged or removed. The recovery key offers a last-resort method of decrypting a FileVault drive. (You can also encrypt other attached drives via the Finder or through the Terminal, but that encryption key is derived from the password you set directly for the drive.) Apple
It’s loaded into memory to decrypt and encrypt data on the fly. When you log into a FileVault-enabled account, the Recovery Disk OS takes your account password and uses that to unlock the encryption key that protects the startup volume. The Recovery Disk, a special partition that first appeared with OS X Lion, manages this initial boot up.
