About Symantec Endpoint If you are using Microsoft
Encryption
Windows Server 2008
Symantec™ Endpoint Encryption is comprised of the Drive
Encryption functionality, the Removable Media Encryption
functionality, and a Management Agent.
■
■
■
Drive Encryption
The Drive Encryption functionality ensures only
authorized access to the data that is stored on hard disks.
This functionality helps safeguard enterprises from data
loss or breach in case of theft or accidental damage to
laptops or PCs.
Removable Media Encryption
The Removable Media Encryption functionality protects
data available on standard, off-the-shelf removable
storage devices. As part of Symantec Endpoint
Encryption, Removable Media Encryption helps prevent
the unauthorized physical or logical access that
jeopardizes the confidentiality of the data on a removable
storage device. Removable Media Encryption provides
file-based encryption using passwords or certificates and
supports external hard drives, USB flash drives, and
portable devices. An Access Utility to enable access to
encrypted files on unmanaged systems (Microsoft
Windows or Mac OS X) is also provided.
Management Agent
Management Agent includes all of the functionalities
that are used across Symantec Endpoint Encryption, such
as authentication methods and settings, registering users
and setting up client administrator accounts and
information.
For Symantec Endpoint Encryption Management Agent to
appear properly on Windows Server 2008 R2, you must

Viewing the encryption status of your
disk
Drive Encryption protects the data that are stored on your
hard disk by encrypting it. Encryption is the process by
which an algorithm renders data unreadable. Only those
who possess the “key” can decrypt the data, thereby
rendering it intelligible again.
The disk of your computer is configured to get encrypted
automatically after you install the Drive Encryption
functionality and restart your computer. Disk encryption
does not even require any user registration and starts even
before you log on to Windows. You can continue to work
normally during and after the encryption of your hard disk.
All partitions should be encrypted, especially the Windows
system partition.
To view the encryption status of your disk
1
On the Start menu, click All Programs > Symantec
Endpoint Encryption > SEE Management Agent.
2
On the Internal Drives tab, click Drives.

View the encryption status of your disk. The status can
be one of the following:
■
Encrypting
Indicates that the encryption of the disk is not yet
complete. Along with this status, the page also
displays the percentage of the disk already
encrypted.
functionality and restart your computer. For disk encryption,
a client computer does not require any user registration.
Drive Encryption silently registers you when you successfully
log in to the computer using Windows credentials after
installation. Drive Encryption uses your Windows password
or token to register you to preboot authentication. Every
time a user logs in to your computer with different Windows
credentials, Drive Encryption automatically registers the
new user.
Note: Preboot authentication does not support certain ALT
characters such as ALT+155. These are special characters
that appear when you press the ALT key and your number
pads. Ensure that you do not use any ALT characters in your
user name or password to avoid any issues during preboot
authentication.
During the silent registration of a client user, Drive
Encryption also enables Single sign-on. When the Single
sign-on is enabled, you can authenticate at preboot and can
directly access your computer without authenticating at
Windows login screen.
Note: Single sign-on is enabled only for client users and not
for client administrators. When a client administrator
authenticates at preboot, the Windows login screen appears.
When you are a registered user, you can use one of the
following options to authenticate and access data on your
computer.
■
Encrypted with a lock icon
Indicates that the disk or partition is fully encrypted.
■
Use Windows credentials at the preboot authentication
screen.
■
Decrypting
Indicates that the decryption of the disk is not yet
complete. Along with this status, the page also
displays the percentage of decryption remaining for
the disk.
■
Use your Token PIN at the token login screen.
■
Not Encrypted
Indicates that the disk is not encrypted. This status
appears for a disk or partition that was encrypted
previously but now is fully decrypted.

of security questions that are predefined and require only
the answers to complete the configuration. Your policy
administrator can also let you customize your questions and
provide answers for them.
Drive Encryption protects the data on a hard disk by
prompting a user of the computer to authenticate before the
Windows operating system starts. When you provide your
credentials to Drive Encryption, it derives the “key”
necessary to render the data on the hard disk intelligible
again.
Security questions are configured after installation of the
Drive Encryption functionality. If you skip configuration
after you log in the first time, Drive Encryption notifies you
to configure Drive Encryption Self-Recovery every time you
log in to your system. Drive Encryption also notifies you to
configure security questions if Drive Encryption
Self-Recovery was enabled after registration through a policy
deployment.
After encryption of the boot disk is initiated, Drive
Encryption displays a preboot authentication screen every
time you start your computer. This screen requires a set of
credentials before it lets you access protected data on the
disk.
Drive Encryption restricts you from accessing your data on
your computer under the following circumstances:
■
When you forget your password (Windows credentials)
or token.
■
When your client computer fails to communicate with
Symantec Endpoint Encryption Management Server
within the schedule that the policy administrator
prescribes.
When you fail to authenticate at preboot, press F4 to use the
recovery options that are configured for your computer as
per the administrative policies. These recovery options help
you bypass the preboot authentication screen once so that
you can reconfigure your authentication credentials.
Based on the administrative policies that are enabled for
your computer, you can have the following recovery options:
■
Drive Encryption Self-Recovery
■
Help Desk Recovery
Additionally, you can also contact your client administrator
to gain access to your computer.
About Drive Encryption Self-Recovery
When you forget your password, Drive Encryption
Self-Recovery assists you to gain access to your computer
without any help desk assistance. You can bypass the preboot
authentication step by answering predefined security
questions correctly.
Drive Encryption Self-Recovery is enabled or disabled for a
user by the administrative policies of Symantec Endpoint
Encryption Management Server. Your policy administrator
can enable Drive Encryption Self-Recovery, in which case
you need to configure a maximum of three security
questions. Your policy administrator can specify the number
When you forget your password, you can select Drive
Encryption Self-Recovery and answer the security questions
to gain access to your computer. After bypassing preboot
authentication, you can contact your local administrator to
reset your Windows login credentials.
Security questions once configured can be used whenever
you need to bypass preboot authentication. In case your
administrator disables Drive Encryption Self-Recovery and
re-enables it, the same security questions can be used to
bypass preboot authentication.
Note: For improved protection, Symantec recommends that
you configure Drive Encryption Self-Recovery the first time
you receive the Drive Encryption Self-Recovery setup after
installation.
See “Configuring Drive Encryption Self-Recovery security
questions” on page 4.

About Help Desk Recovery
With Help Desk Recovery, you can access your encrypted
computer if you lose your password or if there is a lockout
state at preboot. This recovery feature is enabled or disabled
for a computer by the administrative policies of Symantec
Endpoint Encryption Management Server. All you need is
to provide your computer information to the help desk,
receive a Response Key, and then use the Response Key to
access your computer.
A Response Key (also known as One-Time Password) that
the Help Desk Recovery provides is associated with an
encrypted computer, not a user. Each computer has a unique
Response Key that unlocks the encrypted disk on that
computer.
Based on the connectivity of the client with Symantec
Endpoint Encryption Management Server, Help Desk
Recovery offers two types of recovery mode:
■
■
Online Recovery
Online Recovery is possible when the client establishes
a connection with Symantec Endpoint Encryption
Management Server after installation. The server receives
data about the client that it requires to generate a
Response Key in the future. Help Desk Recovery requires
minimum authentication for the computer and does not
involve a Challenge Key.
Offline Recovery
Offline Recovery is required when the client has never
communicated with Symantec Endpoint Encryption
Management Server after installation. The server does
not find any data about the client that it requires to
generate Response Key. Help Desk Recovery requires a
Challenge Key for authentication.
Note: When you recover from a forgotten password, you are
prompted to enter a new password when the Windows
operating system starts. Contact your local administrator
to get your new Windows credentials.
See “Recovering your computer using Help Desk Recovery”
on page 6.
See “Recovering from a communication lockout” on page 7.
Recovering your computer using Help
Desk Recovery
You can use Help Desk Recovery in case of a preboot lockout
or if you forget your user credentials. This recovery feature
requires you to call the help desk, provide your computer
information, receive the Response Key, and use the Response
Key to access your computer.
■
Based on the availability of the recovery information on the
server, preboot authentication displays one of the following
screens when you use Help Desk Recovery:
■
The Help Desk Recovery screen appears when the
recovery information is available on the server and
displays only the computer identity and the Sequence
Number.
■
The Advance Help Desk Recovery screen appears when
the recovery information is not available on the server.
This screen displays the computer identity, the Sequence
Number, and the Challenge Key.
The Response Key box appears on both the screens and
requires you to enter the information that your help desk
administrator provides.
Note: You can press F5 on the Help Desk Recovery screen to
switch to Advance Help Desk Recovery screen. Alternatively,
you can press Esc on the Advance Help Desk Recovery screen
to switch back to Help Desk Recovery.
To recover your computer using Help Desk Recovery
1

option and appears when Drive Encryption
Self-Recovery is enabled and configured for at least one
user on your computer.
For authentication, the following details are required:
■
■
■
Computer
The name of your computer with the domain name. Help
Desk Recovery requires this information to verify the
computer record in the server database.
Sequence Number
A four-digit number that is used to synchronize a client
with the server. Help Desk Recovery requires this
information for generation of a Response Key.
Challenge Key
The public key that the client generates using the public
key of the server. Help Desk Recovery requires this
information to authenticate a client that has never
communicated with the server.
Checksum
A two-character checksum that appears for the Response
Key and the Challenge Key. Checksum helps to verify
that the Challenge Key has been communicated correctly
to the help desk or the Response Key to the user. A
matching checksum confirms that the Challenge Key on
the server side or the Response Key on the client side
have been entered correctly.
3
Call your Symantec Endpoint Encryption Management
Server help desk administrator.
4
From the Help Desk Recovery screen or the Advance
Help Desk Recovery screen, provide the following
information to the help desk administrator:

See “Recovering from a communication lockout” on page 7.
About the communication lockout
Client computers communicate with Symantec Endpoint
Encryption Management Server to send status and recovery
information to the server. For security reasons, your policy
administrator might enforce a check-in policy to monitor
your client computer through periodic contact with the
server. When your client computer fails to communicate
with the server within the prescribed schedule, the computer
is locked out at preboot. When the lockout occurs, the
computer remains in a pre-Windows state after restart. No
registered user can log on to the computer without the
assistance from the help desk or until a client administrator
unlocks the system. The lockout, thereby, protects the data
on your computer if the computer is lost or stolen.
The administrative policies of Symantec Endpoint
Encryption Management Server control the client check-in
enforcement. Your policy administrator might enable
communication lockout and specify a minimum contact
period within which the client must check in to establish
connection with Symantec Endpoint Encryption
Management Server. The administrator can also specify a
warning period during which Drive Encryption should notify
you to communicate with the server. If you do not check in
the client computer within the specified periods, the client
goes into a communication lockout state after next restart.
Based on the policies that are enabled for your computer,
you can use one of the following options to recover from a
communication lockout state:
■
Help desk assistance
You can contact your help desk administrator and request
for a Response Key for your computer.
■
Client administrator assistance
You can contact your Client Administrator. The client
administrator authenticates at the preboot and provides
access to the computer.
After the computer recovers from a communication lockout,
the check-in due date gets extended by the same minimum
contact period and warning period as previous.
See “Recovering from a communication lockout” on page 7.
See “Recovering your computer using Help Desk Recovery”
on page 6.
Recovering from a communication
lockout
When a communication lockout occurs, your client computer
remains in a pre-Windows state after restart. Drive
Encryption displays a dialog box with options to recover
from the lockout state.
Based on the policies that are enabled for your computer,
you can recover your client computer in one of the following
ways:
■
Help desk assistance
The administrative policies of Symantec Endpoint
Encryption Management Server manage this recovery
assistance.
