Security Architecture & Threat Model + +### Security Boundaries +The ChainProof REST Server acts as a multi-tenant analysis platform where untrusted users can submit arbitrary Solidity source files or archive payloads. To protect against malicious or adversarial payloads, the server implements strict security boundaries: + +1. **Authentication Boundary**: Principals are verified via prefixed API keys (`cp_live_...`) hashed with SHA-256 or via OIDC claims (JWTs). +2. **Authorization Boundary**: Scope-based RBAC (`scan:create`, `scan:read`, `scan:cancel`, `scan:delete`, `jobs:manage`, `metrics:read`, `audit:read`, `keys:manage`, `tenant:manage`). +3. **Execution Sandbox Boundary**: Scans run in isolated, single-use per-job file sandboxes (`chainproof-sandboxes/tenant-/job-`) with scrubbed environment variables. +4. **Archive & Bomb Safeguards**: `.zip` archive payloads undergo strict compression ratio checks (max 100:1), uncompressed size limits (max 50MB aggregate, 10MB per file), file count caps (max 500), and path traversal checks (`..`, absolute paths, symlinks). +5. **Data Sanitization & Privacy Boundary**: Errors, stack traces, and findings are scrubbed of host filesystem paths, API keys, and environment secrets before being returned to clients or logged in audit stores. +6. **LLM Transmission Policy Boundary**: Source code transmission to external LLM providers is disabled by default (`allowLLM: false`). + +--- + +## 2. Authentication & Principal RBAC + +### Principals & Roles +- **Roles**: `admin`, `tenant-admin`, `operator`, `viewer`. +- **Scopes**: + - `scan:create`: Submit synchronous or queued scans. + - `scan:read`: Read scan progress, status, and findings. + - `scan:cancel`: Request job cancellation. + - `scan:delete`: Delete job records and results. + - `jobs:manage`: Manage worker queue and job retention. + - `metrics:read`: Read queue, quota, and server metrics. + - `audit:read`: Query tenant audit logs. + - `keys:manage`: Create, rotate, or revoke API keys. + +### API Key Lifecycle & Rotation +- **Prefix**: All production API keys begin with `cp_live_`. +- **Rotation**: Key rotation (`POST /auth/keys/rotate`) issues a new key while maintaining a configurable grace period (default: 24h) during which the retiring key remains valid for smooth client migration. +- **Revocation**: Key revocation (`DELETE /auth/keys/:id`) immediately invalidates a key and logs the revocation reason. + +--- + +## 3. Durable Priority Job Queue & Worker Architecture + +### Job Lifecycle +`queued` ➔ `running` ➔ (`completed` | `failed` | `cancelled` | `timed_out`) + +- **Priorities**: 0 (Critical/Urgent) to 3 (Low). Jobs are dequeued strictly in order of priority, then submission time. +- **Idempotency**: Submitting with an `idempotencyKey` returns the existing job if submitted within the active retention window. +- **Leases & Heartbeats**: Workers acquire a timed lease (default: 30s) and send periodic heartbeats (default: 5s). +- **Crash Recovery**: Stale leases (due to worker crash or unhandled process termination) are automatically detected during periodic sweeps and requeued if `attempts < maxRetries`. +- **Cancellation**: Jobs can be cancelled at any point (`POST /jobs/:id/cancel`). AbortSignals terminate running worker tasks and clean up sandbox temp directories. +- **Status Streaming**: Server-Sent Events (SSE) stream progress (`GET /jobs/:id/stream`) in real-time. + +--- + +## 4. Multi-Tenant Quota & Resource Controls + +Per-tenant resource quotas are actively enforced with structured JSON error responses: + +- **Max Concurrent Jobs**: Default 2 active jobs per tenant. +- **Submission Rate Limits**: Default 100 job submissions per hour. +- **Storage Limits**: Default 500MB total stored results per tenant. +- **Compute Time Limits**: Cumulative CPU scan duration limit per tenant window. + +When a quota is exceeded, the server returns HTTP `429 Too Many Requests` or `413 Payload Too Large` with a structured payload: + +```json +{ + "error": "Tenant 'tenant-acme' has reached maximum concurrent job limit (2/2)", + "code": "QUOTA_EXCEEDED_CONCURRENCY", + "tenantId": "tenant-acme", + "metric": "concurrency", + "limit": 2, + "current": 2, + "retryAfterSeconds": 15 +} +``` + +--- + +## 5.
