# Goal-2 (RBAC Implementation) Task Sheet

## Dependencies
- Goal-1 completion (Core Dispatcher, RBAC Integration, TLS Compliance)
- Security validation fixes from Goal-1-Task-3

## Security Requirements (from SYM-SEC-004)
1. TLS 1.3 REQUIRED for all external communications
2. Certificate OU field MUST map to RBAC roles via signed claims
3. Certificate revocation checks REQUIRED before RBAC validation
4. Full TLS handshake parameters logged for security audits

## Pending Fixes (from security-validation.md)
1. Negative encryption tests (RBAC edge cases)
2. TLS-RBAC integration tests (placeholders exist)
3. Negative TLS protocol validation tests
