# Platform-wide Audit Logging

**ID:** ADM-003
**Priority:** High
**Status:** Planned

## User Story
As a platform administrator, I want to view platform-wide audit logs so that I can monitor security events, investigate incidents, and demonstrate compliance.

## Acceptance Criteria
- [ ] Log all authentication events (login, logout, failed attempts)
- [ ] Log all administrative actions (user changes, config changes)
- [ ] Log all security events (password changes, 2FA changes, token revocations)
- [ ] Searchable log interface with filters
- [ ] Real-time log streaming for monitoring
- [ ] Export logs in standard formats (JSON, CSV, CEF)
- [ ] Log retention configuration
- [ ] Integration with external SIEM systems

## Technical Notes
- Separate from organization audit logs (ORG-007)
- Platform-wide view across all organizations
- Consider ELK stack or similar for log aggregation
- Structured logging format for parsing
- Compliance: SOC 2, ISO 27001, GDPR audit requirements
