7. Lesson 2: Implementing GPOs • What Is Group Policy? How Do You Apply GPOs? How Multiple Local GPOs Work Demonstration: How to Create Multiple Local GPOs Demonstration: How to Configure Local Security Policy Settings

8. What Is Group Policy? Group Policy enables IT administrators to automate one-to-several management of users and computers Use Group Policy to: • Apply standard configurations • Deploy software • Enforce security settings • Enforce a consistent desktop environment Local Group Policy is always in effect for local and domain users, and local computer settings

9. How Do You Apply GPOs? Computer settings are applied at startup and then at regular intervals, while user settings are applied at logon and then at regular intervals Group Policy Processing Order: 4. OU GPOs 1. Local GPOs 3. Domain GPOs 2. Site-level GPOs

10. How Multiple Local GPOs Work You can use MLGPOs to apply different levels of Local Group Policy to local users on a stand-alone computer There are three layers of local GPOs, which are applied in the following order: Local GPO that may contain both computer and user settings Administrators and Non-Administrators Local GPOs are applied next and contain only user settings User-specific Local Group Policy is applied last, contains only user settings, and applies to one specific user on the local computer

11. Demonstration: How to Create Multiple Local GPOs In this demonstration, you will see how to: • Create a custom management console • Configure the Local Computer Policy • Configure the Local Computer Administrators Policy • Configure the Local Computer Non-Administrators Policy • Test multiple local Group Policies

12. Demonstration: How to Configure Local Security Policy Settings In this demonstration, you will see how to review the local Group Policy for security settings

14. Lab Scenario Holly Dickson is the IT manager at A. Datum Corp. She has expressed a concern that some of the laptop computers that users utilize outside of the A. Datum network are susceptible to security breaches. She wants you to investigate how best to configure security and other settings on these computers.

15. Lab Review • Can you create multiple local Group Policies and apply them to different users?

16. Lesson 3: Securing Data with EFS and BitLocker • What Is EFS? Demonstration: How to Encrypt Files and Folders with EFS What Is BitLocker? BitLocker To Go BitLocker Requirements BitLocker Modes Group Policy Settings for BitLocker Configuring BitLocker Configuring BitLocker To Go Recovering BitLocker-Encrypted Drives

17. What Is EFS? EFS is the built-in file encryption tool for Windows file systems: • Enables transparent file encryption and decryption • Provides for encrypted file recovery • Allows encrypted files to be shared with other users

18. Demonstration: How to Encrypt Files and Folders with EFS In this demonstration, you will see how to: • Encrypt files and folders • Confirm the files and folders have been encrypted • Decrypt files and folders • Confirm the files and folders have been decrypted

19. What Is BitLocker? • Windows BitLocker Drive Encryption encrypts the computer operating system and data stored on the operating system volume • Provides offline data protection • Protects all other applications installed on the encrypted volume • Includes system integrity verification • Verifies integrity of early boot components and boot configuration data • Ensures the integrity of the startup process

20. BitLocker To Go Provides enhanced protection against data theft and exposure by extending BitLocker to removable storage devices. When securing a removable drive, you can choose to unlock the drive with either: • A password • A smart card

21. BitLocker Requirements Encryption and decryption key: Hardware Requirements: • BitLocker encryption requires either: • A computer with TPM v1.2 or later • A removable USB memory device • Have enough available hard drive space for BitLocker to create two partitions • Have a BIOS that is compatible with TPM and supports USB devices during computer startup

22. BitLocker Modes Windows 8 supports two modes of BitLocker operation: TPM mode and Non-TPM mode TPM mode • Locks the normal boot process until the user optionally supplies a personal PIN and/or inserts a USB drive containing a BitLocker startup key • Performs system integrity verification on boot components • Non-TPM mode • Uses Group Policy to allow BitLocker to work without a TPM • Locks the boot process similar to TPM mode, but the BitLocker startup key must be stored on a USB drive • Provides limited authentication

23. Group Policy Settings for BitLocker Group Policy provides the following settings for BitLocker: • Turn on BitLocker backup to AD DS • Configure the recovery folder on Control Panel Setup • Enable advanced startup options on Control Panel Setup • Configure the encryption method • Prevent memory overwrite on restart • Configure the TPM validation method used to seal BitLocker keys

24. Configuring BitLocker • Three methods to enable BitLocker: • From System and Settings in Control Panel • Right-click the volume to be encrypted in Windows Explorer, and then select the Turn on BitLocker menu option • Use the manage-bde.wsf command-line tool • Enabling BitLocker initiates a start-up wizard that: • Validates system requirements • Creates the second partition if it does not already exist • Allows you to configure how to access an encrypted drive: • USB • User function keys to enter the Passphrase • No key

25. Configuring BitLocker To Go • Enable BitLocker To Go Drive Encryption by right-clicking the portable device, such as a USB drive, and then clicking Turn On BitLocker • Select one of the following settings to unlock a drive encrypted with BitLocker To Go: • Unlock with a Recovery Password or passphrase • Unlock with a Smart Card • Always auto-unlock this device on this PC

26. Recovering BitLocker-Encrypted Drives • When a BitLocker-enabled computer starts: • BitLocker checks the operating system for conditions indicating a security risk • If a condition is detected: • BitLocker enters recovery mode and keeps the system drive locked • The user must enter the correct Recovery Password to continue • The BitLocker Recovery Password is: • A 48-digit password used to unlock a system in recovery mode • Unique to a particular BitLocker encryption • Can be stored in AD DS • If stored in AD DS, search for it by using either the drive label or the computer’s password

29. Lab Review • What are some ways of protecting sensitive data in Windows 8?

30. Lesson 4: Configuring User Account Control • What Is UAC? How UAC Works Configuring UAC Notification Settings Demonstration: How to Configure UAC with GPOs

31. What Is UAC? UAC is a security feature that simplifies the ability of users to run as standard users and perform all necessary daily tasks • UAC prompts the user for an administrative user’s credentials if the task requires administrative permissions • Windows 8 increases user control of the prompting experience

32. How UAC Works In Windows 8, what happens when a user performs a task requiring administrative privileges? Standard UsersUAC prompts the user for the credentials of a user with administrative privileges AdministrativeUsersUAC prompts the user for permission to complete the task

33. Configuring UAC Notification Settings • UAC elevation prompt settings include the following: • Always notify me • Notify me only when programs try to make changes to my computer • Notify me only when programs try to make changes to my computer (do not dim my desktop) • Never notify

34. Demonstration: How to Configure UAC with GPOs In this demonstration, you will see how to: • Open the User Accounts window • Review user groups • View the Credential prompt • Change UAC settings and view the Consent prompt
