Install Sophos SafeGuard Native Device Encryption on Mac OS X

Transcription

1 Sophos SafeGuard Native Device Encryption is a management tool that is used to manage the recovery key and report on the status of Apple s FileVault 2 encryption. As the underlying technology is FileVault 2, any limitations and experiences with SafeGuard will mirror that of FileVault 2, including the preboot authentication in which a user is prompted to login before Mac OS X completes the boot process. Before you install SafeGuard, make sure to review the following information to help ensure a successful installation: Hardware Software Apple RAID driver Boot Camp Assistant Imaging Disk Types Other Encryption Software Miscellaneous Notes Intel- based Macintosh (PowerPC- based Macs are not supported) At least 2 GB RAM 40 MB available in the file system where SafeGuard will be installed. Mac OS X versions supported: 10.8, 10.9, & Mac OS X is not yet supported. SafeGuard cannot encrypt a RAID configuration as FileVault does not support a RAID volume. You cannot use Boot Camp Assistant to install Boot Camp multi- boot after SafeGuard is installed. Install Boot Camp and complete your Windows installation before you install SafeGuard. Imaging with SafeGuard installed is not supported. SafeGuard Native Device Encryption for Mac can only encrypt internal (standard or solid state) disks. If other encryption software is being used (such as Check Point), ensure the hard drive is decrypted and a reboot has been performed after decryption before installing SafeGuard. Do not install or uninstall on battery power. Do not force a power- off during installation or uninstallation. Back up all data before installation. Make sure the disk is error- free before installation. Do not try to uninstall SafeGuard when the disk is being encrypted. This may cause data loss.

2 If you are attempting to install SafeGuard when the machine is already encrypted with FileVault, you must have the existing FileVault recovery key available to import into SafeGuard. Without it, SafeGuard administrators cannot assist with password recovery and you are at risk of data loss. If you do not have the recovery key, decrypt the machine and go through the normal installation process as follows. If you do have the recovery key, skip to the Installing with FileVault encryption present section. The following describes the installation of Sophos SafeGuard Native Device Encryption on Mac OS X clients. Installation prerequisites Before starting the installation, make sure the SGN server certificate has been imported into the system keychain and is set to Always Trust for SSL.
