Week 11: GuardScript — Security Hardening & Access Control

1. Objectives

  • Finalize security hardening for loader v2/v3 flows on AWS backend.
  • Validate license, HWID, and access-list behavior under workspace scope.
  • Improve runtime observability through logs, metrics, and realtime events.

2. Weekly Tasks Breakdown

DayMain TaskTechnical DetailsStatus
MonLoader Protocol v2 Review- Verified request signature validation, timestamp window, and nonce checks.
- Verified encrypted response and response-signature flow.		Completed
TueLoader Protocol v3 Review- Validated X25519 handshake flow and AES-GCM encryption path.
- Verified response signature integrity checks.		Completed
WedLicense/HWID Hardening- Reviewed HWID lock toggle and reset flow.
- Checked active/expired license rules and project binding logic.		Completed
ThuAccess Policy & Rate Limiting- Verified workspace blacklist/whitelist behavior.
- Verified IP/scope-based rate limiting and TTL cleanup behavior.		Completed
FriLogging & Realtime Auditability- Reviewed workspace log action flow.
- Verified event broadcasting for workspace/user/admin channels.		Completed

3. Key Results

  • Loader execute and handshake paths were validated against current security design.
  • License/HWID enforcement and access-list checks are consistently applied in API flows.
  • Rate limiting behavior is enforced via TTL-backed records in DynamoDB.
  • Workspace-level logging and realtime event propagation are stable for dashboard/admin visibility.

4. Issues & Solutions

  • Issue: Some legacy report claims were not fully aligned with current implementation state.
  • Resolution: Proposal content was normalized to include only repository-verifiable technical claims.

5. Next Steps

  • Finalize end-to-end deployment documentation and validation checklist.
  • Consolidate cleanup and cost-awareness practices for demo readiness.
  • Complete bilingual proposal/worklog synchronization before submission.
