Configure how to access an encrypted drive Use the Set BitLocker startup preferences window. • Select an access option: • USB • Enter the Passphrase by using function keys • No key

  18. Performance & Security • 4 levels of AES encryption • 128 & 256 bit • the diffuser is a new unproven algorithm • diffuser runs in about 10 clock cycles/byte • Combination with AES-CBC for performance & security

  19. BitLocker To Go • Extends BitLocker Drive Encryption to portable devices ü • Manageable through Group Policy ü • Users choose to encrypt portable devices and use them to their fullest capabilities or leave them unencrypted and have them be read-only ü • Enable BitLocker Drive Encryption by right-clicking the device and then clicking Turn On BitLocker ü • Data on encrypted portable devices can be accessed from computers that do not have BitLocker enabled ü • BitLocker can be configured to unlock with one of the following: • Recovery Password or passphrase • Smart Card • Always auto-unlock this device on this PC ü

  28. Windows Defender • Overview • Alert Levels • Windows Defender Tasks

  29. Overview Three ways to help protect the computer: Definitions Real-time protection (RTP) The SpyNet community Scanning options • Used to determine if software that it detects is spyware or other potentially unwanted software, and then to alert you to potential risks. • Works with Windows Update to automatically install new definitions as they are released. • Set Windows Defender to check online for updated definitions before scanning.

  30. Alert Levels Help you choose how to respond to spyware and potentially unwanted software • Severe - remove this software immediately. • High - remove this software immediately. • Medium - review the alert details, consider blocking the software. • Low - review the alert details to see if you trust the publisher. Actions • Quarantine – software is moved to another location on the computer; prevents the software from running until you choose to restore or remove it from the computer. • Remove - permanently deletes the software from the computer. • Allow - adds the software to the Windows Defender allowed list and allows it to run on the computer. Add software to the allowed list only if you trust the software and the software publisher.

  31. Windows Defender Tasks • Turn on Windows Defender ü • Enable real-time protection ü • Automatically check for new definitions ü • Schedule a scan ü • Manually scan for new definitions ü • Windows Defender helps automatically remove malicious software.

  32. Windows Defender • Performance enhancement • Removed the Software Explorer tool

  33. Session Summary Security and User Productivity Enhancements • Customizable UAC requires fewer instances of elevation prompts • Manageable through Group Policy BitLocker and BitLocker To Go • BitLocker To Go extends BitLocker Drive Encryption to password-protected portable media • Users choose to encrypt drive or leave read-only • Manageable through Group Policy AppLocker • Provides a rule-based structure to specify which applications are available to which end users • Create default rules first • View rule event information in the Event Viewer WindowsDefender • Integrated with Action Center • Provides an improved user experience when scanning for spyware or manually checking for updates.
