- Implementation: windows-rs for process attribute detection
- Equivalent to: macOS SIP-protected processes, Linux kernel threads
System Processes#
- Capability: Identify Windows system processes and services
- Implementation: windows-service crate + process analysis
- Equivalent to: macOS system daemons, Linux kernel processes
Process Integrity Levels#
- Capability: Extract process integrity levels (System, High, Medium, Low)
- Implementation: Windows API through windows-rs
- Equivalent to: macOS sandbox entitlements, Linux namespaces
3. Windows-Specific Features#
Windows Services#
- Capability: Detect and monitor Windows services
- Implementation: windows-service crate
- Equivalent to: macOS launchd, Linux systemd
Windows Defender Integration#
- Capability: Handle Windows Defender and antivirus restrictions
- Implementation: Process analysis and registry monitoring
- Equivalent to: macOS SIP restrictions, Linux security modules
Hyper-V and Container Support#
- Capability: Support for Hyper-V containers and Windows Server containers
- Implementation: Container detection through Windows API
- Equivalent to: macOS Docker Desktop, Linux Docker/LXC
4. Performance and Monitoring#
Windows Performance Counters#
- Capability: Access Windows performance counters
- Implementation: Use PDH bindings from the windows or windows-sys crates (Win32::System::Performance) with thin wrappers in our codebase
- Equivalent to: macOS sysctl, Linux /proc/stat
WMI Integration#
- Capability: Windows Management Instrumentation for system info
- Implementation: wmi crate for safe WMI access
- Equivalent to: macOS system information, Linux /proc/sys
Third-Party Crate Strategy#
Primary Crates#
- sysinfo - Cross-platform process enumeration (enhanced)
- windows-rs - Safe Windows API access
- winsafe - Modern, well-maintained Windows API safety wrappers
- winapi-util - Additional Windows API utilities and helpers
Secondary Crates#
- windows-service - Windows service management
- wmi - Windows Management Instrumentation
- windows or windows-sys - PDH performance counter bindings (choose one approach)
- winreg - Windows registry access
Maintenance Status Notes#
- winsafe: Adopted winsafe v0.0.25 for ergonomic PDH counter helpers, strongly typed handle wrappers, and quicker upstream fixes compared to windows/windows-sys
- psutil-rs: Removed due to limited maintenance; sysinfo provides equivalent functionality
- perfmon: Does not provide Windows PDH performance counter support; use PDH bindings via windows or windows-sys crates for performance counters
- MSRV Compatibility: winsafe v0.0.25 is supported (DaemonEye MSRV is 1.87+); the windows/windows-sys crates support MSRV 1.60 for projects with lower MSRV requirements
Safety Considerations#
- No unsafe code - All crates provide safe abstractions
- Error handling - Comprehensive error handling for Windows API failures
- Graceful degradation - Continue with reduced functionality when APIs fail
- Security boundaries - Respect Windows security model
Implementation Plan#
Phase 1: Core Process Collection#
- Implement basic process enumeration using sysinfo
- Add Windows-specific metadata collection
- Handle basic privilege requirements
Phase 2: Security Features#
- Implement SeDebugPrivilege detection
- Add process token analysis
- Handle protected processes
Phase 3: Advanced Features#
- Add Windows service detection
- Implement performance counter access
- Add container support
Phase 4: Integration and Testing#
- Comprehensive Windows-specific tests
- Performance benchmarking
- Cross-platform compatibility validation
Testing Strategy#
Windows-Specific Tests#
- Privilege Tests - SeDebugPrivilege detection and management
- Protected Process Tests - Handle PPL processes gracefully
- Service Tests - Windows service detection and monitoring
- Container Tests - Hyper-V and Windows Server containers
- Performance Tests - Performance counter access and monitoring
Cross-Platform Validation#
- Feature Parity - Ensure equivalent capabilities across platforms
- Performance Comparison - Benchmark against macOS and Linux implementations
- Security Validation - Verify security boundaries are maintained
- Error Handling - Test graceful degradation scenarios
Expected Outcomes#
