Backend Changes:
- Fix user identification to use UPN (User Principal Name) claim as primary identifier instead of display name
- Add JWT authentication validation to all API endpoints with Authorization header support
- Implement Galactic Admin role with cross-tenant access permissions for sessions, events, and SignalR groups
- Add cross-tenant validation in GetSessionEventsFunction, SignalRAddToGroupFunction, and SignalRRemoveFromGroupFunction
- Enhance AuthenticationMiddleware to log actual user identifier (UPN) instead of display name
Admin Configuration:
- Add GetAdminConfigurationFunction and UpdateAdminConfigurationFunction for global settings
- Create AdminConfigurationService for managing platform-wide configuration
- Add AdminConfiguration model with global rate limiting and maintenance settings
- Restrict admin configuration access to Galactic Admins only
SignalR Real-time Updates:
- Implement "galactic-admins" SignalR group for cross-tenant session visibility
- RegisterSessionFunction now sends "newSession" events to both tenant-specific and galactic-admins groups
- IngestEventsFunction sends "newevents" only to tenant-specific groups (prevents flooding)
- Frontend listens to both "newSession" and "newevents" for real-time updates
- Galactic Admins see new sessions from all tenants without being flooded with event updates
Frontend Changes:
- Add Authorization headers with JWT tokens to all API fetch calls (sessions, events, metrics, configuration)
- Implement automatic joining/leaving of "galactic-admins" SignalR group based on Galactic Admin mode
- Handle both "newSession" and "newevents" SignalR events for complete session list updates
- Add authentication error handling with user notifications for token failures
Security Improvements:
- Validate tenant access for all cross-tenant operations
- Ensure users can only access their own tenant data unless they're Galactic Admins
- Log all cross-tenant access attempts with user identifiers for audit trail
- Add JWT-based authentication to all API endpoints
- Implement tenant isolation and access control validation
- Add Galactic Admin role validation for cross-tenant endpoints
- Enhance certificate validation with full X.509 chain checking
- Add certificate validation cache (5-min TTL) and self-signed cert protection
- Implement NDJSON payload size limit protection (configurable per tenant)
- Replace placeholder audit user identifiers with actual JWT user principals
- Add TenantHelper utility for consistent tenant/user extraction from tokens
- Disable PII logging in production (ShowPII = false)
Agent:
- Add automatic tenant ID detection from Windows Registry (AAD Join enrollment)
- Implement tenant ID precedence: CLI argument > Registry > Fallback
SignalR:
- Add authentication checks to all SignalR functions
- Implement tenant-based group access control
- Add user identifier logging for SignalR operations
Frontend:
- Change MSAL cache from localStorage to sessionStorage (XSS protection)
- Add warning status support to health check page
- Add Admin Configuration link in navbar (Galactic Admin only)
- Move maintenance trigger from Settings to Admin Configuration page
- Update tenant context logging for clarity
Configuration:
- Add MaxNdjsonPayloadSizeMB setting to TenantConfiguration model
- Update configuration service to persist new retention/timeout settings
- install only during enrollment
Agent
- added geolocation support
- HelloDetector
- Reboot on complete
- WMI Model parsing fix
...and general small additions here and there
