Overview
This guide assumes that Advanced Authentication is installed with Encryption Personal.
Encryption Personal
The purpose of Encryption Personal is to protect data on your computer, even if the computer is lost or stolen.
To ensure the security of your confidential data, Encryption Personal encrypts data on your Windows computer. You can always access the data when logged into the computer, but unauthorized users do not have access to this protected data. Data always remains encrypted on the drive, but because encryption is transparent, there is no need to change the way you work with applications and data.
Normally, the application decrypts data as you work with it. Occasionally, an application may try to access a file at the same moment that the application is encrypting or decrypting it. If this happens, after a second or two, a dialog is displayed that gives you the option of waiting or canceling the encryption/decryption. If you choose to wait, the application releases the file as soon as it is finished (generally within a few seconds).
Advanced Authentication
The Data Security Console is the interface that guides users through configuring their PBA credentials and self-recovery questions, based on policy set by the local administrator.
See Configure Advanced Authentication Administrator Settings
and refer to the Dell Data Security Console User Guide to learn how to use advanced authentication.

Requirements
These requirements detail everything needed for Encryption Personal installation.
Encryption
• Encryption Personal requires an entitlement to successfully install. The entitlement is supplied when you purchase Encryption Personal.
Depending on how you purchase Encryption Personal, you may manually install the entitlement, using the simple instructions that accompany it. You may also enter the entitlement at the command line. If Encryption Personal is installed using Dell Digital Delivery, the entitlement installation is taken care of by the Dell Digital Delivery service. (The same binaries are used for Encryption Enterprise and
Encryption Personal. The entitlement tells the installer which version to install.)
• To activate a Microsoft Live account with Encryption Personal, refer to KB article SLN290988 .
• A Windows password is required (if one does not already exist) to protect access to your encrypted data. Creating a password for your computer prevents others from logging on to your user account without your password. Encryption Personal will fail to activate if a password is not created.
• Dell Encryption cannot be upgraded to v10.7.0 from versions earlier than v8.16.0. Endpoints running versions prior to v8.16.0 must upgrade to v8.16.0 then upgrade to v10.7.0.
• Dell Encryption uses Intel's encryption instruction sets, Integrated Performance Primitives (IPP). For more information, see KB article
SLN301500 .
1. Go to the Windows Control Panel ( Start > Control Panel ).
2. Click the User Accounts icon.
3. Click Create a password for your account .
4. Enter a new password and re-enter the password.
5. Optionally enter a password hint.
6. Click Create Password .
7. Restart your computer.
• IT best practices should be followed during deployment. This includes, but is not limited to, controlled test environments for initial tests, and staggered deployments to users.
• The user account performing the installation/upgrade/uninstallation must be a local or domain administrator user, which can be temporarily assigned by a deployment tool such as Microsoft SMS. A non-administrator user that has elevated privileges is not supported.
• Back up all important data before beginning installation/uninstallation/upgrade.
• Do not make changes to the computer, including inserting or removing external (USB) drives during installation/uninstallation/ upgrade.
• To reduce initial encryption time (as well as decryption time if uninstalling), run the Windows Disk Cleanup Wizard to remove temporary files and any other unnecessary data.
• Turn off sleep mode during the initial encryption sweep to prevent an unattended computer from going to sleep. Encryption cannot occur on a sleeping computer (nor can decryption).
• The Encryption client does not support dual boot configurations since it is possible to encrypt system files of the other operating system, which would interfere with its operation.
• The master installer does not support upgrades from pre-v8.0 components. Extract the child installers from the master installer and upgrade the component individually. Should you have questions or concerns, contact Dell ProSupport.
• The Encryption client now supports Audit Mode. Audit Mode allows administrators to deploy the Encryption client as part of the corporate image, rather than using a third-party SCCM or similar solutions to deploy the Encryption client. For instructions about how to install the Encryption client in a corporate image, see KB article SLN304039 .
• The TPM is used for sealing the General Purpose Key. Therefore, if running the Encryption client, clear the TPM in the BIOS before installing a new operating system on the target computer.
• Encryption client is tested against and is compatible with several popular signature-based antiviruses and AI-driven antivirus solutions including McAfee Virus Scan Enterprise, McAfee Endpoint Security, Symantec Endpoint Protection, CylancePROTECT, CrowdStrike
Falcon, Carbon Black Defense, and several others. Hard-coded exclusions are included by default for many antivirus providers to prevent incompatibilities between antivirus scanning and encryption.
6 Requirements
If your organization uses an unlisted antivirus provider or any compatibility issues are being seen, please see KB article SLN288353 or
Security solutions.
• Operating system re-install is not supported. To re-install the operating system, perform a backup of the target computer, wipe the computer, install the operating system, then recover the encrypted data following established recovery procedures.
• Be sure to periodically check dell.com/support for the most current documentation and Technical Advisories.
• Following Windows 10 feature upgrade, a restart is required to finalize Dell Encryption. The following message displays in the notification area after Windows 10 feature upgrades:
Prerequisites
• Microsoft .Net Framework 4.5.2 (or later) is required for the master and child installers. The installer does not install the Microsoft .Net
Framework component.
NOTE: .Net Framework 4.6 (or later) is required when running FIPS mode.
• The master installer installs the following prerequisites if not already installed on the computer. When using the child installer , you must install this component before installing Encryption.
Prerequisite
○ Visual C++ 2012 Update 4 or later Redistributable Package (x86 or x64)
○ Visual C++ 2017 Update 3 or later Redistributable Package (x86 or x64)

8 Requirements
Language Support
○ IT - Italian
○ DE - German
○ PT-PT - Portuguese, Portugal (Iberian)
SED Management
• IPv6 is not supported.
• Be prepared to shut down and restart the computer after you apply policies and are ready to begin enforcing them.
• Computers equipped with self-encrypting drives cannot be used with HCA cards. Incompatibilities exist that prevent the provisioning of the HCA. Dell does not sell computers with self-encrypting drives that support the HCA module. This unsupported configuration would be an after-market configuration.
• If the computer targeted for encryption is equipped with a self-encrypting drive, ensure that the Active Directory option, User Must
Change Password at Next Logon , is disabled. Preboot Authentication does not support this Active Directory option.
• Dell Encryption utilizes Intel's encryption instruction sets, Integrated Performance Primitives (IPP). For more information, see KB article SLN301500 .
• NOTE:
Due to the nature of RAID and SEDs, SED Management does not support RAID. The issue with
RAID=On
with SEDs is that RAID requires access to the disk to read and write RAID-related data at a high sector not available on a locked
SED from start and cannot wait to read this data until after the user is logged on. Change the SATA operation in the
BIOS from
RAID=On
to
AHCI
to resolve the issue. If the operating system does not have the AHCI controller drivers pre-installed, the operating system will crash when switched from
RAID=On
to
AHCI
.
• The master installer installs the following prerequisites if not already installed on the computer. When using the child installer , you must install this component before installing SED Management.
Prerequisite
○ Visual C++ 2017 Update 3 or later Redistributable Package (x86 or x64)
Visual C++ 2017 requires Windows Update KB2999226 if installed on Windows 7.
○ In January 2020, SHA1 signing certificates are no longer valid and cannot be renewed. Devices running Windows 7 or Windows
Server 2008 R2 must install Microsoft KBs https://support.microsoft.com/help/4474419 and https://support.microsoft.com/ help/4490628 to validate SHA256 signing certificates on applications and installation packages.
Applications and installation packages signed with SHA1 certificates will function but an error will display on the endpoint during installation or execution of the application without these updates installed
• Configuration of self-encrypting drives for SED Management differ between NVMe and non-NVMe (SATA) drives, as follows.
○ Any NVMe drive that is being leveraged for SED:
▪ The BIOS’ SATA operation must be set to RAID ON, as SED Management does not support AHCI on NVMe drives.
▪ The BIOS's boot mode must be UEFI and Legacy option ROMs must be disabled.
○ Any non-NVMe drive that is being leveraged for SED:
▪ The BIOS’ SATA operation must be set to AHCI, as SED Management does not support RAID with non-NVMe drives.
▪ RAID ON is not supported because access to read and write RAID-related data (at a sector that is not available on a locked non-NVMe drive) is not accessible at start-up, and cannot wait to read this data until after the user is logged on.
▪ The operating system will crash when switched from RAID ON > AHCI if the AHCI controller drivers are not pre-installed. For instructions on how to switch from RAID > AHCI (or vice versa), see KB article SLN306460 .
Supported OPAL compliant SEDs require updated Intel Rapid Storage Technology Drivers, located at www.dell.com/support . Dell recommends Intel Rapid Storage Technology Driver version 15.2.0.0 or later, with NVMe drives.
NOTE: The Intel Rapid Storage Technology Drivers are platform dependent. You can find your system's driver at the link above based on your computer model.
• Direct Feature Updates from Windows 10 v1607 (Anniversary Update/Redstone 1), to the Windows 10 v1903 (May 2019 Update/
19H1) are not supported with Dell Encryption. Dell recommends updating the operating system to a newer Feature Update if updating to Windows 10 v1903. Any attempts to update directly from Windows 10 v1607 to v1903 results in an error message and the update is prevented.
Requirements 9

•
NOTE: A password is required with Pre-boot Authentication. Dell recommends setting a minimum password of 9 or more characters.
NOTE: A password is required for all users added in the
Add User
panel. Zero-length password users will be locked out of the computer following activation.
NOTE: Computers protected by SED Management must be updated to Windows 10 v1703 (Creators Update/
Redstone 2) or later before updating to Windows 10 v1903 (May 2019 Update/19H1) or later. If this upgrade path is attempted, an error message displays.
NOTE: In-place operating system upgrades to a newer version - such as Windows 7 or Windows 8.1 - to Windows 10 is not supported.

10. Click Browse to choose a network drive or removable storage to back up your encryption keys (which are wrapped in an application named LSARecovery_[hostname].exe).
In the event of certain computer failures, these keys are used to recover your data.
In addition, future policy changes sometimes require that your encryption keys get backed up again. If the network drive or removable storage is available, backing up of your encryption keys is done in the background. However, if the location is not available (such as the original removable storage device not being inserted into the computer), policy changes do not take effect until the encryption keys are manually backed up.
NOTE: To learn how to manually back up encryption keys, click "? > Help" in the upper right corner of the Local

Uninstall from the Command Line
• Command line switches and parameters are case-sensitive.
• Be sure to enclose a value that contains one or more special characters, such as a blank space in the command line, in escaped quotation marks. Command line parameters are case-sensitive.
• Use these installers to uninstall the clients using a scripted installation, batch files, or any other push technology available to your organization.
• Log files
Windows creates unique child installer uninstallation log files for the logged in user at %temp%, located at C:\Users\<UserName>
\AppData\Local\Temp.
If you decide to add separate a log file when you run the installer, ensure that the log file has a unique name, as child installer log files do not append. The standard .msi command can be used be create a log file by using /l C:\<any directory>\<any log file name>.log
. Dell does not recommend using "/l*v" (verbose logging) in a command line uninstallation, as the username/password is recorded in the log file.
• All child installers use the same basic .msi switches and display options, except where noted, for command line uninstallations. The switches must be specified first. The /v switch is required and takes an argument. Other parameters go inside an argument that is passed to the /v switch.
Display options can be specified at the end of the argument passed to the /v switch to achieve the expected behavior. Do not use both /q and /qn in the same command line. Only use ! and - after /qb.

True, False, User-Optional
When True, there is no encryption or decryption of data while the user is actively working. The client only processes data when the screen is locked.
User-Optional adds an option to the notification area icon allowing the user to turn this feature on or off.
When False, encryption processing occurs any time, even while the user is working.
Enabling this option significantly extends the amount of time it takes to complete encryption or decryption.
Template Descriptions
Aggressive Protection for All Fixed Drives and External
Drives
This policy template is designed for organizations with a primary goal of enforcing strong security and risk avoidance across the entire enterprise. It is best used when security is significantly more important than usability and the need for less secure policy exceptions for specific users, groups or devices is minimal.
This policy template:
• is a highly restricted configuration, providing greater protection.
• provides protection of the System Drive and all Fixed Drives.
• encrypts all data on removable media devices, and prevents the use of non-encrypted removable media devices.
60 Policies and Template Descriptions
• provides read-only optical drive control.
PCI Regulation Targeted
Payment Card Industry Data Security Standard (PCI DSS) is a multi-faceted security standard that includes requirements for security management, policies, procedures, network architecture, software design, and other critical protective measures. This comprehensive standard is intended to set the guidelines for organizations to proactively protect customer account data.
This policy template:
• provides protection of the System Drive and all Fixed Drives.
• prompts users to encrypt removable media devices.
• provides the ability to write only UDF CD/DVDs. Port control configuration allows read access to all optical drives.
Data Breach Regulation Targeted
The Sarbanes-Oxley Act requires adequate controls for financial information. Because much of this information resides in electronic format, encryption is a key control point when this data is stored or transferred. The Gramm-Leach-Bliley (GLB) Act (also known as the
Financial Services Modernization Act) guidelines do not require encryption. However, the Federal Financial Institutions Examination Council
(FFIEC) recommends that, "Financial institutions should employ encryption to mitigate the risk of disclosure or alteration of sensitive information in storage and transit." California Senate Bill 1386 (California's Database Security Breach Notification Act) aims to protect
California residents from identity theft by requiring organizations that have had computer security breaches to notify all affected individuals. The only way an organization can avoid notifying customers is to be able to prove all personal information was encrypted prior to a security breach.
This policy template:
• provides protection of the System Drive and all Fixed Drives.
• prompts users to encrypt removable media devices.
• provides the ability to write only UDF CD/DVDs. Port control configuration allows read access to all optical drives.
HIPAA Regulation Targeted
The Health Insurance Portability and Accountability Act (HIPAA) mandates that healthcare organizations implement a number of technical safeguards to protect the confidentiality and integrity of all individually identifiable health information.
This policy template:
• provides protection of the System Drive and all Fixed Drives.
• prompts users to encrypt removable media devices.
• provides the ability to write only UDF CD/DVDs. Port control configuration allows read access to all optical drives.
Basic Protection for All Fixed Drives and External Drives
(Default)
This policy template provides the recommended configuration, which provides a high level of protection without significantly impacting system usability.
This policy template:
• provides protection of the System Drive and all Fixed Drives.
• prompts users to encrypt removable media devices.
• provides the ability to write only UDF CD/DVDs. Port control configuration allows read access to all optical drives.
Basic Protection for All Fixed Drives
This policy template:
• provides protection of the System Drive and all Fixed Drives.
• provides the ability to write CD/DVDs in any supported format. Port control configuration allows read access to all optical drives.
This policy template does not:
Policies and Template Descriptions 61
• provide encryption for removable media devices.
Basic Protection for System Drive Only
This policy template:
• provides protection of the System Drive, typically the C: drive, where the operating system is loaded.
• provides the ability to write CD/DVDs in any supported format. Port control configuration allows read access to all optical drives.
This policy template does not:
• provide encryption for removable media devices.
Basic Protection for External Drives
This policy template:
• provides protection of removable media devices.
• provides the ability to write only UDF CD/DVDs. Port control configuration allows read access to all optical drives.
This policy template does not:
• provide protection for the System Drive (typically the C: drive, where the operating system is loaded) or other Fixed Drives.
Encryption Disabled
This policy template does not provide encryption protection. Take additional measures to safeguard devices from loss and theft when using this template.
This template is useful for organizations that prefer to start with no active encryption to transition into security. As the organization becomes comfortable with their deployment, encryption can be enabled slowly by adjusting individual policies or by applying stronger templates for portions of or for the entire organization.

Extract Child Installers
• To install each client individually, extract the child executable files from the installer.
• If the master installer has been used to install, the clients must be uninstalled individually. Use this process to extract the clients from the master installer so that they can be used for uninstallation.
1. From the Dell installation media, copy the DDSSetup.exe
file to the local computer.
2. Open a command prompt in the same location as the DDSSetup.exe
file and enter:
DDSSetup.exe /z"\"EXTRACT_INSTALLERS=C:\extracted\""
The extraction path cannot exceed 63 characters.
Before you begin installation, ensure that all prerequisites have been met and all required software has been installed for each child
installer that you plan to install. Refer to Requirements for details.
The extracted child installers are located at C:\extracted\.
Proceed to
Extract Child Installers 63

Troubleshooting
Upgrading to the Windows 10 April 2018 Update
Computers running Encryption must use a specially configured Windows 10 Upgrade package to upgrade to the Windows 10 October 2018
Update. The configured version of the upgrade package ensures that Encryption can manage access to your encrypted files to protect them from harm during the upgrade process.
To upgrade to the Windows 10 April 2018 Update, follow the instructions in KB article SLN298382 .
Dell Encryption Troubleshooting
(Optional) Create an Encryption Removal Agent Log File
• Before beginning the uninstall process, you can optionally create an Encryption Removal Agent log file. This log file is useful for troubleshooting an uninstall/decryption operation. If you do not intend to decrypt files during the uninstall process, you do not need to create this log file.
• The Encryption Removal Agent log file is not created until after the Encryption Removal Agent service runs, which does not happen until the computer is restarted. Once the client is successfully uninstalled and the computer is fully decrypted, the log file is permanently deleted.
• The log file path is C:\ProgramData\Dell\Dell Data Protection\Encryption.
• Create the following registry entry on the computer targeted for decryption.
[HKLM\Software\Credant\DecryptionAgent]
"LogVerbosity"=DWORD:2
0: no logging
1: logs errors that prevent the service from running
2: logs errors that prevent complete data decryption (recommended level)
3: logs information about all decrypting volumes and files
5: logs debugging information
Find TSS Version
• TSS is a component that interfaces with the TPM. To find the TSS version, go to (default location) C:\Program Files\Dell
\Dell Data Protection\Drivers\TSS\bin > tcsd_win32.exe
. Right-click the file and select Properties . Verify the file version on the Details tab.
Encryption External Media and PCS Interactions
To Ensure Media is Not Read-Only and the Port is Not Blocked
The EMS Access to unShielded Media policy interacts with the Port Control System - Class: Storage > Subclass Storage: External Drive
Control policy. If you intend to set the EMS Access to unShielded Media policy to Full Access , ensure that the Subclass Storage: External
Drive Control policy is also set to Full Access to ensure that the media is not set to read-only and the port is not blocked.
To Encrypt Data Written to CD/DVD
• Set Windows Media Encryption = On.
• Set EMS Exclude CD/DVD Encryption = not selected.
• Set Subclass Storage: Optical Drive Control = UDF Only.
64 Troubleshooting
Use WSScan
• WSScan allows you to ensure that all data is decrypted when uninstalling Encryption as well as view encryption status and identify unencrypted files that should be encrypted.
• Administrator privileges are required to run this utility.
NOTE: WSScan must be run in System Mode with the PsExec tool if a target file is owned by the system account.
Run WSScan

Check Encryption Removal Agent Status
The Encryption Removal Agent displays its status in the description area of the services panel (Start > Run > services.msc > OK) as follows. Periodically refresh the service (highlight the service > right-click > Refresh) to update its status.
• Waiting for SDE Deactivation - Encryption is still installed, is still configured, or both. Decryption does not start until Encryption is uninstalled.
• Initial sweep - The service is making an initial sweep, calculating the number of encrypted files and bytes. The initial sweep occurs one time.
• Decryption sweep - The service is decrypting files and possibly requesting to decrypt locked files.
• Decrypt on Reboot (partial) - The decryption sweep is complete and some locked files (but not all) are to be decrypted on the next restart.
• Decrypt on Reboot - The decryption sweep is complete and all locked files are to be decrypted on the next restart.
• All files could not be decrypted - The decryption sweep is complete, but all files could not be decrypted. This status means one of the following occurred:
○ The locked files could not be scheduled for decryption because they were too big, or an error occurred while making the request to unlock them.
○ An input/output error occurred while decrypting files.
○ The files could not be decrypted by policy.
○ The files are marked as should be encrypted.
○ An error occurred during the decryption sweep.
○ In all cases, a log file is created (if logging is configured) when LogVerbosity=2 (or higher) is set. To troubleshoot, set the log verbosity to 2 and restart the Encryption Removal Agent service to force another decryption sweep.
• Complete - The decryption sweep is complete. The service, the executable, the driver, and the driver executable are all scheduled for deletion on the next restart.

How to Encrypt an iPod with Encryption External Media
These rules disable or enable encryption for these folders and file types for all removable devices - not just an iPod. Use care when defining rules.
• Dell does not recommend the use of the iPod Shuffle, as unexpected results may occur.
• As iPods change, this information could also change, so caution is advised when allowing the use of iPods on Encryption External
Media-enabled computers.
• Because folder names on iPods are dependent on the model of the iPod, Dell recommends creating an exclusion policy which covers all folder names, across all iPod models.
• To ensure encrypting an iPod via Encryption External Media does not make the device unusable, enter the following rules in the
Encryption External Media Encryption Rules policy:
-R#:\Calendars
-R#:\Contacts
-R#:\iPod_Control
-R#:\Notes
-R#:\Photos
• You can also force encryption of specific file types in the directories above. Adding the following rules will ensure that ppt, pptx, doc, docx, xls, and xlsx files are encrypted in the directories excluded from encryption via the previous rules:
^R#:\Calendars;ppt.doc.xls.pptx.docx.xlsx
^R#:\Contacts;ppt.doc.xls.pptx.docx.xlsx
^R#:\iPod_Control;ppt.doc.xls.pptx.docx.xlsx
^R#:\Notes;ppt.doc.xls.pptx.docx.xlsx
^R#:\Photos;ppt.doc.xls.pptx.docx.xlsx
• Replacing these five rules with the following rule will force encryption of ppt, pptx, doc, docx, xls, and xlsx files in any directory on the iPod, including Calendars, Contacts, iPod_Control, Notes, and Photos:
^R#:\;ppt.doc.xls.pptx.docx.xlsx
• Rules have been tested against these iPods: iPod Video 30gb fifth generation iPod Nano 2gb second generation iPod Mini 4gb second generation

Troubleshooting 81
Encryption
(Optional) Create an Encryption Removal Agent Log File
• Before beginning the uninstall process, you can optionally create an Encryption Removal Agent log file. This log file is useful for troubleshooting an uninstall/decryption operation. If you do not intend to decrypt files during the uninstall process, you do not need to create this log file.
• The Encryption Removal Agent log file is not created until after the Encryption Removal Agent service runs, which does not happen until the computer is restarted. Once the client is successfully uninstalled and the computer is fully decrypted, the log file is permanently deleted.
• The log file path is C:\ProgramData\Dell\Dell Data Protection\Encryption.
• Create the following registry entry on the computer targeted for decryption.
[HKLM\Software\Credant\DecryptionAgent]
"LogVerbosity"=DWORD:2
0: no logging
1: logs errors that prevent the service from running
2: logs errors that prevent complete data decryption (recommended level)
3: logs information about all decrypting volumes and files
5: logs debugging information
Use Smart Cards with Windows Log On
• To determine if a smart card is present and active, ensure the following value is set:
HKLM\SOFTWARE\Dell\Dell Data Protection\
"SmartcardEnabled"=DWORD:1
If SmartcardEnabled is missing or has a value of zero, the Credential Provider will display only Password for authentication.
If SmartcardEnabled has a non-zero value, the Credential Provider will display options for Password and smart card authentication.
• The following registry value indicates whether Winlogon should generate a notification for logon events from smart cards.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
"SmartCardLogonNotify"=DWORD:1
0 = Disabled
1 = Enabled
Preserve Temp Files During Installation
• By default, all temporary files in the c:\windows\temp directory are automatically deleted during installation. Deletion of temporary files speeds initial encryption and occurs before the initial encryption sweep.
However, if your organization uses a third-party application that requires the file structure within the \temp directory to be preserved, you should prevent this deletion.
To disable temporary file deletion, create or modify the registry setting as follows:
[HKLM\SOFTWARE\CREDANT\CMGShield]
"DeleteTempFiles"=REG_DWORD:0
Not deleting temporary files increases initial encryption time.
Change the Default Behavior of the User Prompt to Begin or Delay Encryption
• The Encryption client displays the length of each policy update delay prompt for five minutes each time. If the user does not respond to the prompt, the next delay begins. The final delay prompt includes a countdown and progress bar, and it displays until the user responds, or the final delay expires and the required logoff/reboot occurs.
You can change the behavior of the user prompt to begin or delay encryption, to prevent encryption processing following no user response to the prompt. To do this, set the registry the following registry value:
[HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\CMGShield]
"SnoozeBeforeSweep"=DWORD:1
Any non-zero value changes the default behavior to snooze. With no user interaction, encryption processing is delayed up to the number of configurable allowed delays. Encryption processing begins when the final delay expires.
82 Troubleshooting
Calculate the maximum possible delay as follows (a maximum delay would involve the user never responding to a delay prompt, each of which displays for 5 minutes):
(NUMBER OF POLICY UPDATE DELAYS ALLOWED × LENGTH OF EACH POLICY UPDATE DELAY) + (5 MINUTES × [NUMBER OF
POLICY UPDATE DELAYS ALLOWED - 1])
Change the Default Use of SDUser Key
• System Data Encryption (SDE) is enforced based on the policy value for SDE Encryption Rules. Additional directories are protected by default when the SDE Encryption Enabled policy is Selected. For more information, search "SDE Encryption Rules" in AdminHelp.
When Encryption is processing a policy update that includes an active SDE policy, the current user profile directory is encrypted by default with the SDUser key (a User key) rather than the SDE key (a Device key). The SDUser key is also used to encrypt files or folders that are copied (not moved) into a user directory that is not a encrypted with SDE.
To disable the SDUser key and use the SDE key to encrypt these user directories, create the following registry entry on the computer:
[HKEY_LOCAL_MACHINE\SOFTWARE\Credant\CMGShield]
"EnableSDUserKeyUsage"=DWORD:00000000
If this registry key is not present or is set to anything other than 0, the SDUser key is used to encrypt these user directories.
Disable/Enable Encrypt for Sharing in Right-click Context Menu
• To disable or enable the Encrypt for Sharing option in the right-click menu use the following registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Dell\Dell Data Protection\Encryption
"DisplaySharing"=DWORD
0 = disable the Encrypt for Sharing option in the right-click context menu
1 = enable the Encrypt for Sharing option in the right-click context menu
Disable/Enable the notification for Encryption Personal activation
• HKCU\Software\Dell\Dell Data Protection\Encryption
"HidePasswordPrompt"=DWORD
1 = disables the password prompt for Encryption Personal activation
0 = enables the password prompt for Encryption Personal activation
Advanced Authentication
Disable Smart Card and Biometric Services (Optional)
If you do not want Advanced Authentication to change the services associated with smart cards and biometric devices to a startup type of "automatic", you can disable the service startup feature.
When disabled, Authentication does not attempt to start these three services:
• SCardSvr - Manages access to smart cards read by the computer. If this service is stopped, this computer is unable to read smart cards. If this service is disabled, any services that explicitly depend on it fail to start.
• SCPolicySvc - Allows the system to be configured to lock the user desktop upon smart card removal.
• WbioSrvc - The Windows biometric service gives client applications the ability to capture, compare, manipulate, and store biometric data without gaining direct access to any biometric hardware or samples. The service is hosted in a privileged SVCHOST process.
Disabling this feature also suppresses warnings associated with the required services not running.
• By default, if the registry key does not exist or the value is set to 0, this feature is enabled.
[HKEY_LOCAL_MACHINE\SOFTWARE\DELL\Dell Data Protection]
SmartCardServiceCheck=REG_DWORD:0
Set to 0 to Enable.
Set to 1 to Disable
Use Smart Cards with Windows Log On
• To determine if the PBA is activated, ensure that the following value is set:
[HKLM\SYSTEM\CurrentControlSet\services\DellMgmtAgent\Parameters]
"PBAIsActivated"=DWORD (32-bit):1
A value of 1 means that the PBA is activated. A value of 0 means the PBA is not activated.
Troubleshooting 83
NOTE: Manually deleting this key can create unintended results for users syncing with the PBA resulting in the need for manual recovery.
• To determine if a smart card is present and active, ensure the following value is set:
HKLM\SOFTWARE\Dell\Dell Data Protection\
"SmartcardEnabled"=DWORD:1
If SmartcardEnabled is missing or has a value of zero, the Credential Provider will display only Password for authentication.
If SmartcardEnabled has a non-zero value, the Credential Provider will display options for Password and smart card authentication.
• The following registry value indicates whether Winlogon should generate a notification for logon events from smart cards.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
"SmartCardLogonNotify"=DWORD:1
0 = Disabled
1 = Enabled
Proceed to

• To prevent SED management from disabling third-party credential providers, create the following registry key:
HKLM\SOFTWARE\Dell\Dell Data Protection\
"AllowOtherCredProviders" = DWORD:1
0=Disabled (default)
1=Enabled
• The Encryption Management Agent no longer outputs policies by default. To output future consumed policies, create the following registry key:
HKLM\Software\Dell\Dell Data Protection\
DWORD: DumpPolicies
Value=1
Note: a reboot is required for this change to take effect.
• To suppress all Toaster notifications from the Encryption Management Agent, the following registry value must be set on the client computer.
[HKEY_LOCAL_MACHINE\SOFTWARE\Dell\Dell Data Protection]
"PbaToastersAllowClose" =DWORD:1
0=Enabled (default)
1=Disabled

Glossary
Advanced Authentication - The Advanced Authentication product provides smart card reader options. Advanced Authentication helps manage these multiple authentication methods, supports login with self-encrypting drives, SSO, and manages user credentials and passwords.
Encryption Administrator Password (EAP) - The EAP is an administrative password that is unique to each computer. Most configuration changes made in the local Management Console require this password. This password is also the same password that is required to use your LSARecovery_[hostname].exe file to recover data. Record and save this password in a safe place.
Encryption Client - The Encryption client is the on-device component that enforces security policies, whether an endpoint is connected to the network, disconnected from the network, lost, or stolen. Creating a trusted computing environment for endpoints, the Encryption client operates as a layer on top of the device operating system, and provides consistently-enforced authentication, encryption, and authorization to maximize the protection of sensitive information.
Encryption keys - In most cases, Encryption uses the User encryption key plus two additional encryption keys. However, there are exceptions: All SDE policies and the Secure Windows Credentials policy use the SDE key. The Encrypt Windows Paging File policy and
Secure Windows Hibernation File policy use their own key, the General Purpose Key (GPK). The Common encryption key makes files accessible to all managed users on the device where they were created. The User encryption key makes files accessible only to the user who created them, only on the device where they were created. The User Roaming encryption key makes files accessible only to the user who created them, on any encrypted Windows or Mac device.
Encryption sweep - The process of scanning folders to be encrypted to ensure the contained files are in the proper encryption state.
Ordinary file creation and rename operations do not trigger an encryption sweep. It is important to understand when an encryption sweep may happen and what may affect the resulting sweep times, as follows: - An encryption sweep occurs upon initial receipt of a policy that has encryption enabled. This can occur immediately after activation if your policy has encryption enabled. - If the Scan Workstation on
Logon policy is enabled, folders specified for encryption are swept on each user logon. - A sweep can be re-triggered under certain subsequent policy changes. Any policy change related to the definition of the encryption folders, encryption algorithms, encryption key usage (common verses user), triggers a sweep. In addition, toggling between encryption enabled and disabled triggers an encryption sweep.
Pre-boot Authentication (PBA) - Pre-boot Authentication serves as an extension of the BIOS or boot firmware and guarantees a secure, tamper-proof environment external to the operating system as a trusted authentication layer. The PBA prevents anything being read from the hard disk, such as the operating system, until the user has confirmed they have the correct credentials.
Single Sign-On (SSO) - SSO simplifies the logon process when multi-factor authentication is enabled at both preboot and Windows logon.
If enabled, authentication is required at preboot only, and users are automatically logged on to Windows. If not enabled, authentication may be required multiple times.
System Data Encryption (SDE) - SDE is designed to encrypt the operating system and program files. To accomplish this purpose, SDE must be able to open its key while the operating system is booting. Its intent is to prevent alteration or offline attacks on the operating system by an attacker. SDE is not intended for user data. Common and User key encryption are intended for sensitive user data because they require a user password to unlock encryption keys. SDE policies do not encrypt the files needed by the operating system to start the boot process. SDE policies do not require preboot authentication or interfere with the Master Boot Record in any way. When the computer boots up, the encrypted files are available before any user logs in (to enable patch management, SMS, backup and recovery tools). Disabling SDE triggers automatic decryption of all SDE encrypted files and directories for the relevant users, regardless of other
SDE policy values, such as SDE Encryption Rules.
Trusted Platform Module (TPM) - TPM is a security chip with three major functions: secure storage, measurement, and attestation. The
Encryption client uses TPM for its secure storage function. The TPM can also provide encrypted containers for the software vault.
