3. We have a firewall
We can‘t get
hacked!

4. Agenda:
The threat landscape
No-brainers to secure Windows 10
Latest & greatest mitigation features in Windows 10

5. The discussion is always about tools!

6. Threat Landscape
Phishing
Keylogger
Ransomware Spyware
Worm Compromised accounts

7. Analysis: High-level vulnerability & exploit trends
Vulnerabilities are increasing while evidence of actual exploits is decreasing due to mitigation investments

10. No-Brainer: Microsoft BitLocker
• Full drive encryption solution provided natively with Windows 10 Professional and Enterprise
• Used to protect the operating system drive, secondary data drives and removable devices
• System Center Configuration Manager, MDT and Intune can be used to deploy BitLocker

12. Windows Defender Credential Guard
• Uses virtualization-based security to isolate secrets in the Local Security Authority (LSA) .
• Only privileged system software can access secrets when stored locally.
• Mitigates credential theft attacks, such as Pass-the-Hash (PtH) or Pass-The-Ticket (PtT).
Overview

13. Windows Defender Credential Guard
Overview
• Credential Guard isolates secrets that previous versions of Windows stored in the Local Security
Authority (LSA) by using virtualization-based security.
• The LSA process in the operating system talks to the isolated LSA by using remote procedure calls.
• Data stored by using VBS is not accessible to the rest of the operating system.

14. Get deeper into attack scenarios
Good to
know
Exploit:
Computercode that takes advantage of a vulnerability in a software system.
Payload:
Payloads carry the functionality for the greater access into the target.

15. Scenario

PayloadExploit
Common way‘s to share payloads:
• Fake Hyperlink
• PowerPoint Macro
• as „JPG“ File

16. Create a payload with Metasploit

19. Windows Defender SmartScreen
• The Windows Defender SmartScreen provides an early warning system to notify users of
suspicious websites that could be engaging in phishing attacks or distributing malware through a
socially engineered attack.
• Windows Defender SmartScreen is one of the multiple layers of defense in the anti-phishing and
malware protection strategies

21. Windows Defender Application Guard
• Windows Defender Application Guard protects the device from advanced attacks launched against
Microsoft Edge.
• Malware and vulnerability exploits targeting the browser, including zero days, are unable to impact
the operating system, apps, data and network.
• Application Guard uses virtualization based security to hardware to isolate Microsoft Edge and any
browsing activity away from the rest of the system.
• Closing Microsoft Edge wipes all traces of attacks that may been encountered while online.

27. User Account Control
• User Account Control (UAC) helps prevent malware from damaging PCs
and helps organizations deploy a better-managed desktop.
• Apps and tasks always run in the security context of a standard user
account, unless an administrator specifically authorizes elevated access to
the system

28. Windows Defender Device Guard
Device Guard Kernel Mode Code Integrity
• Protects kernel mode processes and drivers from “zero day” attacks and
vulnerabilities by using HVCI.
• Drivers will must signed.
Device Guard User Mode Code Integrity
• Enterprise-grade application white-listing that achieves PC lockdown for enterprise that runs only
trusted apps.
• Untrusted apps and executables, such as malware, are unable to run.

• Windows Defender Exploit Guard helps you audit, configure, and manage Windows system and
application exploit mitigations .
• In addition Exploit Guard delivers a new class of capabilities for intrusion prevention.
While it provides legacy app protections including:
• Arbitrary Code Guard
• Block Low Integrity Images
• Block Remote Images
• Block Untrusted Fonts
• Code Integrity Guard
• Disable Win32k system calls
• Validate Stack Integrity
• Do Not Allow Child Processes
• Export Address Filtering
• Import Address Filtering
• Simulate Execution
• Validate API Invocation (CallerCheck)
• Validate Image Dependency Integrity
