Hard_Configurator is a GUI application to configure various Windows security features and apply recommended defaults.
- Minimum standards for a highly secure Windows device (Secure-Core)
- Windows up-to-date
- Microsoft Defender up-to-date
- Latest Driver and Program updates
- Only necessary programs/apps/games which you need
- avoid insecure software like 7-Zip (which lacks Anti-Exploit and MOTW support) and also Forks, Open/ LibreOffice, Firefox, True/Veracrypt, ...
- stay away from "Anti-Spying"/"Anti-Telemetry"/.. tools and use official documentation
- No "Tuning" tools (not even stuff like Ccleaner!)
- Hardware Requirements for System Guard / Hardware-based Isolation
- Hardware Requirements for Memory integrity
- Hardware Requirements for Microsoft Defender Credential Guard
- Set User Account Control (UAC) to maximum
- Create a different Admin account and transform your current account to limited/restricted/standard user to reduce the attack surface enormously. Don't use administrator access for your tasks!
- Use Smart App Control
- Block all incoming connections with Microsoft Defender Firewall
- Always display file type extension
- Manage Microsoft Defender Credential Guard
- Enable Memory Integrity (HVCI)
- Enable Network Protection (NP)
- Enable SmartScreen and enable SmartScreen Logs
- Enable Controlled Folder Access (CFA)
- Enable Attack Surface Reduction rules (ASR)
- Enable Mandatory ALSR and Bottom-Up-ALSR (Address Space Layout Randomization)
- Enable System Guard Secure Launch
- Enable cloud-delivered protection
- Enable protection against Potentially Unwanted Apps (PUA)
- Enable Bitlocker Encryption with TPM, optionally with Startup PIN & read about Countermeasures to reduce DMA threats
- Use Windows Sandbox for new/unknown binaries (you can use it with the right click menu) or enable Hyper-V for use with Microsoft's Virtual Machine Platform
- Enable sandboxing for Microsoft Defender Antivirus
- Only elevate executables which are signed and validated
- Use the only browser that natively supports hardware isolation: Edge
- Use EFS file encryption for very sensitive files - also compatible with Bitlocker
- Harden OneDrive with Windows Controlled Folder Access (CFA aka Ransomeware Protection)
- Avoid old file systems like FAT32 that do not preserve Alternative NTFS Streams (where Mark Of The Web is skipped)
- While DNS encryption isn't perfect both Quad9 and Cloudflare are recommend. AdGuard and NextDNS are another, but some users report problems like false positive filtering, stability/performance issues.
- Specify the cloud-delivered protection level
- Configure Microsoft's Exploit Protection and Enforced CET
- Use Microsoft's recommended block rules
- Control USB devices and other removable media
- See UEFI Hardening aka NSA Defensive Practices Guidance and Hardware-and-Firmware-Security-Guidance
- See Hardware and Firmware Security Guidance for Windows and AMD CPUs
- Deploy Windows Security Baselines and keep it up-to-date
- Use Mandatory Integrity Control
- Use Security-ADMX custom template focused on hardening Windows 10 systems
- Application Control (WDAC) - Microsoft's Policy Wizard will help a lot
- Enterprise Certificate Pinning
- Block untrusted fonts in an enterprise
- Web protection
- Protect Remote Desktop credentials with Windows Defender Remote Credential Guard
- Manage Windows Hello for Business
- Protect against DLL Search Order Hijacking
