12. Bitlocker Modes
• Basic Mode:
- TPM only
• Advanced Modes:
- TPM + PIN
- TPM + USB Dongle
- USB Dongle
- TPM + PIN + USB Dongle

13. Windows 8 And Bitlocker
• Pre-encrypt, ask for pin on first logon
• Only encrypt sectors with data
• Bitlocker Network Unlock

14. Bitlocker Are Vulnerable When:
• The Disk Have Not Yet Been Totally Encrypted
• You Don’t Use Pin
• Especial If The Computer Have Or Might Get:
• Firewire
• Thunderbolt
• Fake Bios Startup (To Get Pin)

15. Important To Do
• Use Bitlocker
• Use Pin
• Change Pin
• Disable Possibility to use
- Firewire
- Thunderbolt

16. If You Can’t Use Bitlocker Yet

17. Bitlocker Requirements
• A computer running:
• Windows 7 Enterprise (x86/x64)
• Windows 7 Ultimate (x86/x64)
• Windows Server 2008 R2
• With TPM
• A Trusted Computing Group (TCG)-compliant BIOS
• TPM microchip version 1.2 (turned on)
• TPM must be resettable from the operating system
• Removable Storage
• USB
• Floppy
• Memory Card

18. Enable Bitlocker On A Virtual Machine For TESTING:
1. Set “Allow Bitlocker without compatible TPM” In a GPO
2. Create a virtual floppy disk
3. Enable bitlocker with «manage-bde»
cscript c:WindowsSystem32manage-bde.wsf -on C: -rp -sk A:
4. Restart and it will start to encrypt

20. THE VANILA TASTE
BITLOCKE WITHOUT
MBAMM

21. Enabling Bitlocker Server Side
• On The Schema Master:
- C:TempBitlocker Scrip>ldifde -i -v -f
BitLockerTPMSchemaExtension.ldf -c "DC=X"
"DC=DomainName,DC=com" -k -j .
• On Any DC
- cscript Add-TPMSelfWriteACE.vbs

22. Enabling Bitlocker Client Side
• During Deployment
• Best way, but some «challenges»
• After Deployment
• Manual or script

23. Management
• Script
• Active Directory User And Computer
• ADSI Edit
• No Feedback
• No Reporting

25. And Always Remember!!!

29. What is Microsoft BitLocker Administration
and Monitoring (MBAM)?
• MBAM builds on the BitLocker data protection offering in Windows
7 by providing IT professionals with an enterprise-grade solution
for BitLocker provisioning, monitoring, and key recovery.
GOALS ARE:
Simplify provisioning Provide reporting Reduce support costs
1 and deployment 2 (e.g.: compliance 3 (e.g.: improved
& audit) recovery)

30. Prerequisites For Server
• Operation System:
Windows Server 2008 SP2 (x86/x64)
Windows Server 2008 R2
• Database:
• Compliance and Audit Report Server
• Microsoft Sql Server 2008 R2 Std/Ent/Dev
• Recovery and Hardware Database Server
• Microsoft Sql Server 2008 R2 Enterprise Only
• Security reason: Transparent Data Encryption
(TDE)

32. Installing Mbam
• Single computer configuration
• Everything on a single server.
Supported, but only recommended for testing purposes.
• Three-computer configuration
• Recovery and Hardware Database, Compliance and Audit Reports, and
Compliance and Audit Reports features are installed on a server
• Administration and Monitoring Server feature is installed on a server
• Group Policy template is installed on a server or client computer.
• Five-computer configuration
• Each server feature is installed on dedicated computers:
• Recovery and Hardware Database
• Compliance Status Database
• Compliance and Audit Reports
• Administration and Monitoring Server
• Group Policy Template is installed on a server or client computer

33. Installing Mbam
• Or In Most Cases 2 Computer
• 1 Sql
• 1 Mbam w/Group Policy Template
• Need To Have GPMC Installed
Group Policy Template Server?

34. Prerequisites For Clients
• A computer running:
• Windows 7 Enterprise (x86/x64)
• Windows 7 Ultimate (x86/x64)
• A Trusted Computing Group (TCG)-compliant
BIOS
• TPM microchip version 1.2 (turned on)
• TPM must be resettable from the operating
system

35. MBAM Client
• Encrypt volumes BEFORE a user receives the computer
• Works with Windows 7 deployment tools (MDT/SCCM)
• Client can:
• Manage TPM reboot process
• Be configured with TPM first and PIN later (e.g.: user provides PIN at
first logon)
• Recovery key escrow can be bypassed and then escrowed when user
first logs on
• Best Practice
• Encrypt volumes AFTER a user receives a computer
• Client is provides a Policy Driven Experience
• Client will manage TPM reboot process
• Standard or Admin users can encrypt
• Only use when unencrypted machines appear on the network

36. MBAM Policy Settings
• A superset of BitLocker policies
• New MBAM Policies
• Policy for Fixed Disk Volume Auto-unlock
• Hardware capability check before encryption
• Allow user to request an exemption
• Interval client verifies policy compliance
(default = 90 min)
• Policy location:
• Computer Configuration > Administrative Templates >
Windows Components > MDOP MBAM (BitLocker
Management)

37. Client Experience

38. Client Troubleshooting
BdeHdCfg.exe -target c: shrink -size 300 -quiet –restart http://support.microsoft.com/kb/933246

39. Hardware Capability Management
• Some older computers may not properly support
TPM
• To ensure those computers aren’t encrypted, a
feature is included that can be used to define
which computers are BitLocker capable
• How you turn it on:
• Group Policy setting so client checks before
encryption starts
• From Central Console, define computers that
are capable or not

40. How It Works
•
1 New Computer Discovered, Info Added To
Central HW List
2 State Need To be Modified On Website By
•
Operator With Permissions
3 When Feature Is Enabled Only Compatible
•
Computers Will Be Encrypted
4 Mbam Client Check Compatibility Before
•
Encrypting (Make/Model/Bios Version)

41. Troubleshooting:
• “HKLMSoftwareMicrosoftMBAM”
Create Dword “NoStartupDelay” value=1
Create Dword “DisableMachineVerification” value=1
• Prevent Delay Of Hardware Compatibility Checking
delete this 2 keys and restart the MBAM agent:
HKLMsoftwaremicrosoftMBAMHWExemptionTimer
HKLMsoftwaremicrosoftMBAMHWExemptionType
HWExemptionType are 0=unknown,1=incompatible,2=compatible
• Mbam Fails To Start Encrypt Disk

been added?
• MBAM agent collects and passes data to
reporting server
• All clients pass this up, encrypted or not
• IT can clarify WHY a computer is not compliant
• Built on SQL Server® Reporting Services
(SSRS), it gives you
flexibility to add your own reports

43. Troubleshooting/Speeding Up Reporting:

44. Central Storage of Recovery Key
• Recovery Key(s) are Escrowed
• Operating System Volume
• Fixed Data Volumes
• Removable Data Volumes
• Stored outside of Microsoft Active Directory®
• 3-Tier Architecture
• DB encrypted with SQL Server’s Transparent
Data Encryption
• Web Service API to build org-specific solutions
• All logging and authorization are done at web
service layer to ensure parity for custom apps

45. Helpdesk Key Recovery UI
• MBAM provides a web page for helpdesk functionality
• Provide BitLocker Recovery Key for authorized users
• Provide TPM unlock package for authorized users
• All requests (successful or not) are logged:
who, when, which volume
• Role based authorization model to get recovery info
• Tier 1: Helpdesk needs to have
person/key match
• Tier 2: Key ID is sufficient (limited role)
• Create your own custom page leveraging web service
layer

46. Single Use Recovery Keys
• Once a BitLocker Recovery key has been
exposed , the client will create a new one
• As part of regular client/server communication,
client checks to
see if Recovery Key has been exposed
• MBAM client will create new one
• Transparent to user
• Recovery Keys are created once a volume is
unlocked
