Introduction
The Encryption Enterprise for Mac Administrator Guide provides the information needed to deploy and install the client software.
Topics:
•
•
•
Overview
Encryption Enterprise for Mac can manage FileVault full disk encryption.
● Encryption Enterprise for Mac - client encryption software that encrypts all data and enforces access control
●
- used to distribute policies
●
Security Server - used for client encryption software activations
● Security Management Server or Security Management Server Virtual - provides centralized security policy administration, integrates with existing enterprise directories and creates reports. For the purposes of this document, both Servers are cited as Dell Server, unless a specific version needs to be cited (for example, a procedure is different using Security Management
Server Virtual).
These Dell components inter-operate seamlessly to provide a secure mobile environment without detracting from the user experience.
FileVault Encryption
Dell Encryption can manage Mac FileVault full disk encryption. The Dell Volume Encryption policy must be set to On for encryption to take place and for other policy settings to function. For information on additional policies, see AdminHelp .
Only FileVault encryption is supported, which Encryption Enterprise will manage. If a computer has the Dell Volume Encryption policy set to On and Encrypt Using FileVault for Mac set to Off , a policy conflict message displays on the Encryption client. The administrator must set both policies to On .

Install/Upgrade Encryption Enterprise for Mac
This section guides you through the Encryption Enterprise for Mac installation/upgrade and activation process.
There are two methods to install/upgrade Encryption Enterprise for Mac. Select one of the following:
●
Interactive Installation/Upgrade and Activation
- This method is the easiest method to install or upgrade the client software package. However, this method does not allow any customizations. If you intend to use Boot Camp or a version of operating system that is not yet fully supported by Dell (through .plist modification), you must use the command line installation/ upgrade method. For information about using Boot Camp, see
.
●
administrators experienced with command line syntax. If you intend to use Boot Camp or a version of operating system that is not yet fully supported by Dell (through .plist modification), you must use this method to install or upgrade the client software package. For information about using Boot Camp, see
For more information on the Installer Command options, see the Mac OS X Reference Library at http://developer.apple.com.
Dell highly recommends using remote deployment tools, such as Apple Remote Desktop, to distribute the client installation package.
NOTE:
Apple often releases new versions of operating systems between releases of Encryption Enterprise for Mac. To support as many customers as possible, a modification of the com.dell.ddp.plist file is allowed to support these cases. Testing of these versions begins as soon as Apple releases a new version, to ensure that they are compatible with Encryption
Enterprise for Mac.
Prerequisites
Dell recommends that IT best practices are followed during the deployment of client software. This includes, but is not limited to, controlled test environments for initial tests and staggered deployments to users.
Before beginning this process, ensure the following prerequisites are met:
● Ensure that the Dell Server and its components are already installed.
If you have not yet installed the Dell Server, follow the instructions in the appropriate guide below.
Security Management Server Installation and Migration Guide
Security Management Server Virtual Quick Start Guide and Installation Guide
● Ensure that you have the Security Server and Policy Proxy URLs handy. Both are needed for client software installation and activation.
8 Tasks for the Encryption Client
● If your deployment uses a non-default configuration, ensure that you know the port number for the Security Server. It is needed for client software installation and activation.
● Ensure that the target computer has network connectivity to the Security Server and Policy Proxy.
● Ensure that you have a domain user account in the Active Directory installation configured for use with the Dell Server. The domain user account is used for client software activation. Configuring Mac endpoints for domain (network) authentication is not required.
Before setting encryption policies, the Dell Volume Encryption policy must be On.
. Be sure that you understand the Encrypt
Using FileVault for Mac and Volumes Targeted for Encryption policies.
For more information about encryption policies, see Mac Encryption > Dell Volume Encryption
.
Interactive Installation or Upgrade
To install or upgrade and activate the client software, follow the steps below. You must have an administrator account to perform these steps.

Activate Encryption Enterprise for Mac
.
macOS 10.15 and higher with removable media
If an enterprise uses removable media with macOS 10.15 and higher, users must enable full disk access for external media. For
more information, see Enable Full Disk Access for Removable Media
.
Command Line Installation/Upgrade
To install the client software using the command line, follow these steps.
Command Line Installation
1. From the Dell installation media, mount the Dell-Encryption-Enterprise-<version>.dmg file.
2. Copy the Install Dell Encryption Enterprise package and the com.dell.ddp.plist
file to the local drive.
3. In the Management Console, modify the following policies if needed. Policy settings override .plist file settings. Use .plist
settings if policies do not exist in the Management Console.
● No Auth User List - In some cases, you may want to edit this policy so that specified users or classes of users do not have to activate against the Dell Server. For example, in an educational facility, teachers would be prompted to activate their computer against the Dell Server, but individual students using lab computers would not. The lab administrator could use this policy and the account running the client tool so that student users could log in without being prompted to activate. For information on the client tool, see
. If an enterprise needs to know which user account is associated with each Mac computer, all users must activate against the Dell Server, so that enterprise would not edit this property. However, if a user wants to provision Encryption External Media, the user must be authenticated against the
Dell Server.
4. Open the .plist file and edit any additional placeholder values:
NOTE:
Apple often releases new versions of operating systems between releases of Encryption Enterprise for Mac. To support as many customers as possible, Dell allows a modification of the .plist file to support these cases. As soon as Apple releases a new version, Dell begins testing these versions to ensure that they are compatible with Encryption Enterprise for Mac.

Encryption Process
The encryption process varies depending on the state of the boot volume when encryption is enabled.
NOTE:
To maintain the integrity of user data, the client software does not begin encrypting a volume until the verification process is successful on that volume. If a volume fails verification, the client software notifies the user and reports the failure in
Dell Data Protection Preferences. If you need to repair a volume, follow the instructions in Apple Support article HT1782
( http://support.apple.com/kb/HT1782 ). The client software re-attempts verification on the next computer restart.
Select one of these:
●
FileVault encryption of an unencrypted volume
●

FileVault Encryption of an Unencrypted Volume
With FileVault encryption, an additional unnamed user displays in the PBA. Do not delete this user as it allows the Dell Server to enforce policy on the device. If the PBA user is removed, the user will need to take action to begin policy-mandated decrypts.
1. After installation and activation, you must log into the account you want to boot from after FileVault encryption is active.
2. Wait for validation of the drive and verification of the volume to complete.
3. Enter the password for the account.
18 Tasks for the Encryption Client
NOTE:
If you allow this dialog to time out, you must reboot or log in for the password dialog to display again.
4. Click OK .
5. Be sure that each user has a secure token. See https://www.dell.com/support/article/us/en/19/sln309192/mobile-usersunable-to-activate-dell-encryption-enterprise-for-mac-on-macos-high-sierra?lang=en .
If the account the user was logged into is a non-mobile network account, a dialog displays. After the boot drive is encrypted, the drive can be booted only by the user who was logged in during FileVault initialization.
This account must be a local or network mobile account. To change non-mobile network accounts to mobile accounts, go to
System Preferences > Users and Groups . Do one of the following:
● Make the account a mobile account.
OR
● Log into a local account and initialize FileVault from that location.
6. Click OK .
7. After encryption preparation is complete, restart the computer.
NOTE:
Depending on the User Experience policies set in the Management Console, the client software may prompt the user to restart the computer.
8. After the computer restarts, it must be connected to the network for the client software to escrow recovery information to the Dell Server.
The client software can begin and complete the encryption process, as well as report encryption status to the Management
Console, all before user login. This allows you to enforce compliance across all Mac computers without requiring user interaction.
Modify Policy to Add FileVault Users
FileVault secures the data on a disk by automatically encrypting it. In a managed FileVault boot volume, to allow multiple users to unlock the disk, you can modify a policy in the Management Console and use your dictionary of OpenDirectory record names and values to then allow users to add themselves to the FileVault disk.
1. In the Management Console's advanced Mac Global Settings policies, scroll to the FileVault 2 PBA User List policy.
2. In the FileVault 2 PBA User List policy field, enter a rule that matches the users you plan to specify. For example, matching
<string>*</string> for any key should match all users that the bound OpenDirectory server has.
Tags are case sensitive, and the entire value must be properly formed as dictionary and array elements in a property list.
Dictionary keys are AND'd together. Array values are or'd together so matching any element in an array matches for the entire array.
NOTE:
If a rule is improperly formed, an error displays in the Dell Encryption Enterprise > Preferences tab.
The following <dict> lists examples for two keys:
<dict>
<key>dsAttrTypeStandard:AuthenticationAuthority</key>
<array>
<string>;Kerberosv5;;user1@LKDC:*</string>
<string>;Kerberosv5;;user2@LKDC:*</string>
<string>;Kerberosv5;;user3@LKDC:*</string>
<string>;Kerberosv5;;z*@LKDC:*</string>
</array>
<key>dsAttrTypeStandard:NFSHomeDirectory</key>
<string>/Users/*</string>
</dict>
● The sample AuthenticationAuthority key entries specify a pattern of user1 , user2 , and user3 or any user id that begins with z . To view the dialog that provides the correct syntax for each user, press the Control-Option-Command keys on the client. Copy the syntax for the user, and paste it to the Management Console.
Tasks for the Encryption Client 19
NOTE:
For this example, trailing asterisks represent the latter part of the authentication authority records. Typically, to avoid under-specifying, include the complete record instead of a trailing asterisk because the asterisk matches any information after the colon in the OpenDirectory record.
● The NFSHomeDirectory key requires that any user passing the first key must also have a home directory in /Users/ .
NOTE:
You must create the home folder if one does not exist for a user.
3. Reboot the computers.
4. Notify users to enable FileVault booting for their user account. The user must have a local or mobile account. Network accounts are automatically converted to mobile accounts.
For a user to enable their FileVault account:
1. Launch System Preferences , and click Dell Encryption Enterprise .
2. Click the System Volumes tab.
3. Control-click the System Volume drive, and select Add FileVault users to FileVault Booting .
4. In Search , enter a user's name or scroll down. User accounts display only if they meet the criteria set by policy.
For local and mobile users, an Enable User button displays.
For network users, a Convert & enable user button displays.
NOTE:
A green indicator displays next to user accounts that can boot FileVault.
5. Click Enable User or Convert & enable user .
6. Enter the password for the selected account and click OK . A progress indicator displays.
7. After a success dialog, click Done .
Assume Management of an Existing FileVault-Encrypted Volume
If the computer already has a FileVault-encrypted volume and FileVault encryption is enabled in the Management Console, Dell
Encryption can assume management of the volume.
If Dell Encryption detects that the boot volume is already encrypted, the Dell Encryption Enterprise dialog displays. To allow Dell
Encryption to assume management of the volume, follow these steps.
1. Select either Personal Recovery Key
or
Bootable Account Credentials .
NOTE:
For macOS High Sierra and Apple File System (APFS), you must select Bootable Account Credentials .
● Personal Recovery Key - if you have the personal recovery key you received when the drive was FileVaultencrypted.
a. Enter the key.
If a user does not have the existing key, they can request it from the administrator.
b. Click OK .
NOTE:
After the assumption process is complete, a new personal recovery key is generated and escrowed. The previous recovery key is invalidated and removed.
● Bootable Account Credentials - if you have the username and password of an account that is currently authorized to boot from the volume.
a. Enter the user name and password.
b. Click OK .
2. When a dialog displays indicating that Dell now manages encryption of the volume, click OK .
If Dell Encryption detects that a non-boot volume is already encrypted, a passphrase prompt displays.
20 Tasks for the Encryption Client
3. (FileVault-encrypted non-boot volumes only) To allow Dell Encryption to assume management of the volume, enter the passphrase to access the volume. This is the password that was assigned to the volume when it was originally FileVaultencrypted.
Once Dell manages the volume's encryption, the old password is no longer valid. Your Dell administrator can retrieve a recovery key for your volume in the event that you should need recovery assistance.
If you choose not to enter the password, the volume's contents are accessible and are encrypted with FileVault but the encryption is not managed by Dell.
NOTE:
In the Management Console, the administrator can see that the Dell Server now manages the endpoint.
Recycling FileVault Recovery Keys
If you have security issues with a recovery bundle or if a volume or keys are compromised, you can recycle the key material for that volume.
You can recycle keys for boot and non-boot drives on Mac OS X.
To recycle the key material:
1. Download a recovery bundle from the Management Console and copy it to the computer's desktop.
2. Launch System Preferences and click Dell Encryption Enterprise .
3. Click the System Volumes tab.
4. Drag the recovery bundle from step 1 to the appropriate partition.
A dialog prompts you to cycle the FileVault keys.
5. Click OK .
A dialog confirms success for cycling keys.
6. Click OK .
NOTE:
Keys in the recovery bundle for this drive are now obsolete. You must download a new recovery bundle from the
Management Console.
User Experience
For maximum security, the client software disables the Automatic Login feature of Mac OS X computers.
Additionally, the client software automatically enforces the Mac OS X feature require password after sleep or screen saver begins . Also, a configurable amount of time is allowed in sleep/screen saver mode before enforcing authentication. The client software allows a user to set a value up to five minutes before authentication is enforced.
Users can use the computer normally as the encryption sweep progresses. All data on the currently booted system volume is being encrypted, including the operating system, while the operating system continues to operate.
If the computer is restarted or enters system sleep, the encryption sweep pauses and then automatically resumes after the restart or wake.
The client software does not support the use of hibernation images, which the Mac OS X Safe Sleep feature uses to wake the computer if the battery is fully discharged during sleep.
To reduce user impact, the client software automatically updates the system sleep mode to disable hibernation and enforces this setting. The computer can still enter sleep, but the current system state is maintained only in memory. Therefore, the computer is fully restarted if completely shut down during sleep, which could occur if the battery runs down or is replaced.
Copy allowlist rule
A hidden menu item allows a user to copy a allowlist rule for removable media.
Tasks for the Encryption Client 21
1. Launch System Preferences and click Dell Encryption Enterprise .
2. Select the Removable Media tab.
3. Right-click a drive row, and simultaneously press the command key.
A hidden menu item displays.
4. Click Copy allowlist rule for the current removable media. The allowlist rule is copied to the Clipboard.
5. Access the Clipboard, copy the allowlist rule, and send it to your administrator.
If the Mac Media Encryption policy is toggled On , data is encrypted, including Thunderbolt drives.
To exclude a device or group of devices to prevent writing encrypted data to the Thunderbolt drive or to Encryption External
Media, use the allowlist rule to modify the values.
Use the complete rule to specify a particular drive for allowlisting, for example: bus=USB;fstype=HFS+;tbolt=0;size=4006608896;USBPRODUCTNUM=5669;USBPRODNAME=DT101
II;USBVENDORNAME=Kingston;USBVENDORNUM=2385;USBSERNUM=001CC0EC3447AA308699119F
NOTE:
Be sure to replace the sample values with the information for your drive.
NOTE:
You must enable HFS Plus. See Enable HFS Plus
.
To exclude SATA devices from Mac Media Encryption policy enforcement when connected via Thunderbolt: tbolt=1;bus=SATA
You can also allowlist or exclude media from Encryption External Media based on:
● Media size
Allowlist rule to exclude large media from Encryption External Media protection: size <op> <size specifier>
<op> can be =, <=, >=, <, >
<size specifier> is of the form decimal integer with an optional suffix from {K, M, G, T} aligned on 1000, not 1024. For example, to exclude media or a drive greater than 500000000 bytes from Encryption External Media, use one of these: size >= 500000000 size >= 500000K size >= 500M
● File system type
Allowlist rule: fstype=<fstype>
<fstype> can be ExFAT, FAT, or HFS+
To exclude both, here is an example for 1TB and greater HFS+ media: size>=1T;fstype=HFS+
Recovery
Occasionally, you may need access to data on encrypted disks. As a Dell administrator, you can access encrypted disks without decrypting them, saving you valuable time.
You might need to access a user's encrypted data for many reasons, but a few common use cases are as follows:
● Someone leaves the company, and no one knows the password.
● A user cannot recall the password.
22 Tasks for the Encryption Client
This section guides you through the process of using
FileVault Recovery when FileVault encryption is on the endpoint to be
recovered. FileVault can be used with Encryption Enterprise for Mac v8.11 or later running on macOS Sierra 10.12.6. FileVault recovery is also used on Fusion Drives.
FileVault Recovery
Recovery of a managed FileVault-encrypted volume is dictated by Apple and is automated where possible but requires a few more steps.
The Dell Recovery Utility simplifies the operation of Apple's recovery tools with scripts to assist with mounting a volume or, in some cases, decrypting it. FileVault recovery functionality is determined by the operating system installed on the Recovery HD and the paired target partition.
A FileVault-encrypted volume can be recovered only from a Recovery HD partition that is written to all disk drives running
Mac OS X 10.9.5 or later. This requirement eliminates the possibility of performing a recovery operation directly from the Dell
Recovery Utility.
Two recovery methods exist, based on whether the FileVault recovery key is a personal or institutional recovery key. One valid recovery key always exists. If a personal recovery key exists, Dell recommends that you use the most recent entry for that key.
If that key does not work, then use the institutional recovery keychain.
●
- Existing FileVault encryption is managed by the Dell Server. If the most recent entry in the recovery
bundle contains a RecoveryKey entry, follow the Personal Recovery Key
steps. Here is a RecoveryKey example:
RecoveryKey</key><string>C73W-CX2B-ANFY-HH3K-RLRE-LVAK</string>
●
(rarely used) - This recovery method is based on use of a FileVault institutional recovery key.
steps. Here is a
KeychainKey example:
KeychainKey</key><data>a3ljaAABAAAAA...

Recovery of Encryption Enterprise for Windows on Boot Camp
Mac OS X Boot Camp Support
NOTE:
When using Boot Camp, Dell Encryption Enterprise does not encrypt the Windows operating system. Also, if two or more bootable macOS partitions exist on the device, Encryption Enterprise encrypts only the primary volume.
Boot Camp is a utility included with Mac OS X that assists you in installing Windows on Mac computers in a dual-boot configuration. Boot Camp is supported with the following Windows operating systems:
● Windows 7 and 7 Home Premium, Professional, and Ultimate (64-bit)
● Windows 8.1 and 8.1 Pro (64-bit)
NOTE:
Windows 7 is Boot Camp 4 or 5.1. Windows 8.1 and higher is Boot Camp 5.1 only.
To use Encryption Enterprise for Windows in Boot Camp on a computer with Encryption Enterprise for Mac, the system volume must be encrypted through Encryption Enterprise with FileVault2. See the
Command Line Installation/Upgrade
for instructions.
NOTE:
If your Windows partition is a candidate for Encryption External Media, be sure to allowlist it or it will be encrypted. See
.
NOTE:
You must ensure Windows is installed before deploying client policies enabling encryption. After the client begins the encryption process, it disallows disk partition operations required by Boot Camp.
Recovery of Encryption Enterprise for Windows on
Boot Camp
To recover Encryption Enterprise for Windows running in a Boot Camp volume, you must also create a Boot Camp volume on an external drive.
Prerequisites
● An external bootable drive
● The Device ID/Unique ID of the computer targeted for recovery. In most cases, you can find the computer targeted for recovery in the Management Console by searching for the owner's user name and viewing the devices encrypted for that user. The format of the Device ID/Unique ID is "John Doe's MacBook.Z4291LK58RH".
Process
1. On an external drive, create a Boot Camp volume.
The steps are similar to creating a Boot Camp volume on your local system. See http://www.apple.com/support/ bootcamp/ .
2. From the Management Console, copy the recovery bundle to one of these:
30 Using Boot Camp
● Bootable USB drive or

Client Tool
The Client Tool is a shell command that runs on a Mac endpoint. It is used to activate the client from a remote location or to run a script through a remote management utility. As administrator, you can activate a client and do the following:
● Activate as administrator
● Activate temporarily
● Retrieve information from the Mac client
To use the Client Tool manually, open a ssh session and enter the desired command on the command line.
Example:
/Library/PreferencePanes/Dell\ Encryption\Enterprise.prefPane/Contents/Helpers/ client -at domainAccount domainPassword
Enter client alone to display the usage instructions.
/Library/PreferencePanes/Dell\ Encryption\Enterprise.prefPane/Contents/Helpers/client

Disk
Activates a Mac client with the Dell
Server but without going through the user interface. To activate, a valid domain user name and password must be entered.
With the client tool you can activate a different local user than the one logged in and associate the domain credentials with that user.
-a domainAccount domainPassword
-a localAccount* domainAccount domainPassword domainAccount is the account used to activate via the client tool.
localAccount is optional and is the current user if none is specified.
The activation command has this format: client -a <user to activate*> <domainUser>
<domainPassword>
If you use the No Auth User List policy to create classes of users that do not get activated to the Dell Server, optionally, you can use the client tool to specify a different
local account than the one logged in. See No
Auth User List policy in step 3
