Phases + +### Phase 1: Core SAML Service (Week 1) +- [ ] SAML types and models +- [ ] SAML service layer (using `samlify` or `passport-saml`) +- [ ] Metadata generation and parsing +- [ ] Certificate validation +- [ ] Basic SP-initiated SSO flow +- [ ] Unit tests + +### Phase 2: REST API (Week 1-2) +- [ ] `/api/auth/saml/initiate` endpoint +- [ ] `/api/auth/saml/callback` endpoint +- [ ] `/api/auth/session` validation +- [ ] `/api/auth/logout` endpoint +- [ ] `/api/saml/metadata` generation +- [ ] Integration tests + +### Phase 3: IdP Management (Week 2) +- [ ] MongoDB schema for IdP configuration +- [ ] CRUD endpoints (`/api/admin/idps/*`) +- [ ] Metadata URL auto-fetch +- [ ] Certificate expiry monitoring +- [ ] Admin UI integration (optional) + +### Phase 4: Security & Production (Week 2-3) +- [ ] Assertion replay prevention +- [ ] Rate limiting on SSO endpoints +- [ ] Comprehensive security testing +- [ ] Docker integration with Keycloak/Authentik +- [ ] Production deployment guide + +### Phase 5: Documentation (Week 3) +- [ ] API reference documentation +- [ ] Integration guides (web, mobile, API gateway) +- [ ] Example implementations (React, Node.js, Python) +- [ ] Troubleshooting guide +- [ ] Security best practices + +## Technology Stack + +- **SAML Library**: `samlify` (lightweight, well-maintained) +- **Alternative**: `passport-saml` (if using Passport.js) +- **XML Parsing**: `xml2js`, `xmlbuilder2` +- **Certificate**: `node-forge` for certificate validation +- **Backend**: Keycloak or Authentik (Docker) - optional enhancement +- **Testing**: Jest, supertest, SAML test IdP + +## Security Considerations + +1. **Assertion Validation** + - Signature verification + - Certificate chain validation + - Timestamp validation (NotBefore, NotOnOrAfter) + - Audience restriction + - Recipient validation + +2. **Replay Attack Prevention** + - Track used assertion IDs + - Short assertion lifetime (5 minutes) + - Redis-based assertion ID cache + +3. **Session Management** + - Secure session cookies (httpOnly, secure, sameSite) + - Session timeout (8 hours default) + - Activity-based session refresh + - Single logout support + +4. **Certificate Management** + - Automated metadata refresh (daily) + - Certificate expiry warnings (30 days) + - Multiple certificate support (rotation) + +5. **Rate Limiting** + - SSO initiate: 10 requests/minute per IP + - Callback: 20 requests/minute per IP + - Admin API: 100 requests/hour per admin + +## Success Metrics + +- ✅ Support for major IdPs (Okta, Azure AD, OneLogin, Auth0, Google Workspace) +- ✅ Generic REST API works with ANY client (not just FlexGate) +- ✅ SP and IdP-initiated SSO flows +- ✅ Single Logout (SLO) support +- ✅ Multi-tenant isolation +- ✅ 90%+ test coverage +- ✅ Comprehensive documentation with examples +- ✅ Security audit passed +- ✅ Production deployment ready + +## Estimated Timeline + +- **Phase 1**: 20-24 hours (Core SAML service) +- **Phase 2**: 12-16 hours (REST API) +- **Phase 3**: 8-12 hours (IdP management) +- **Phase 4**: 16-20 hours (Security & production) +- **Phase 5**: 8-12 hours (Documentation) + +**Total**: 64-84 hours (8-10.5 working days) + +## Future Enhancements + +- LDAP/Active Directory integration +- SCIM 2.0 user provisioning +- Multi-factor authentication (MFA) +- Advanced RBAC mapping from SAML attributes +- SAML artifact binding +- Enhanced audit logging +- Real-time IdP health monitoring diff --git a/package-lock.json b/package-lock.json index e8da619..822a002 100644 --- a/package-lock.json +++
