This document provides an overview of managing Bitlocker encryption with Microsoft Desktop Optimization Pack (MDOP). It discusses using Bitlocker encryption to encrypt drives on devices and the benefits of using disk encryption. It then compares managing Bitlocker without using Microsoft Bitlocker Administration and Monitoring (MBAM) versus using MBAM. Managing Bitlocker without MBAM involves manual scripts and management with no reporting capabilities, while MBAM simplifies deployment, provides reporting on compliance and auditing, and reduces support costs through improved key recovery.

- 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

- 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)
- 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 %windir%system32bdeHdCfg.exe -target default -size 300 -quiet http://social.technet.microsoft.com/Forums/en/w7itprosecurity/thread/9e6dc763-03e5-421c-b0c5-33ca89477880 http://social.technet.microsoft.com/Forums/en-US/w7itprosecurity/thread/ecd17002-0f06-4a62-845c-920442adb2b5 http://social.technet.microsoft.com/Forums/en/w7itprosecurity/thread/0f62a250-2eb7-4e9a-aab8-bc4cafb6f71a
- 42. Compliance and Reporting Need to know how effective Who and when keys Need to know the your rollout is, or how have been accessed and last known state of a compliant your company is? when new hardware has lost computer? 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
- 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
