> **🆕 What changed since last review (v1.1 → v1.2, 2026-04-20):**
> - 📈 **IMF elevated to a primary external economic data source** (parity with SCB and World Bank) per [ADR 0001](docs/adr/0001-adopt-imf-data-alongside-world-bank.md). Existing row **TB-6a** covers the `imf-ts-client` data flow in detail; this revision additionally: (a) adds IMF to the **Critical Assets** inventory under "Parliamentary Data / Economic Context", (b) notes two IMF-specific residual risks — **projection-vintage confusion** (WEO vintage drift: an old WEO dataset cited as current; mitigated by `projectionVintage` sidecar + Economic Data Contract v2.0 field) and **cache poisoning of `analysis/data/imf/`** (mitigated by `.meta.json` integrity sidecars, SBOM-covered schema validation, and Git-tracked diffs under PR review), and (c) adds an **"IMF upstream / transport adversary"** row to the Threat Agent Classification Framework (low likelihood; controls already enumerated in TB-6a).
>
> **🆕 What changed since last review (v1.0 → v1.1, 2026-04-20):**
> - Full **STRIDE pass** re-executed over the current architecture of Riksdagsmonitor `v0.8.48`:
>   - **Spoofing:** GitHub OIDC federation to AWS (no long-lived keys); npm provenance attestations; MCP server TLS + token-scoped auth.
>   - **Tampering:** SRI on all static assets via `vite-plugin-sri-gen@1.3.2`; Git signed commits; immutable S3 object versioning + CloudFront origin signing; schema-validated CIA data ingestion (`validate-against-cia-schemas`); translation integrity via `validate-translations`.
>   - **Repudiation:** GitHub audit log + CloudTrail; signed releases; SLSA L3 provenance on npm; Actions run logs retained.
>   - **Information Disclosure:** Public classification by design, but secrets scanning, CodeQL, Dependabot alerts, and `step-security/harden-runner` guard against accidental exfiltration from build runners.
>   - **Denial of Service:** CloudFront absorbs L3/L7 volumetrics; WAF rate-limiting; dual-region failover; GitHub Pages DR tier; npm package remains available independently of web tier.
>   - **Elevation of Privilege:** Least-privilege `permissions:` on every workflow; PR-gated merges; five-layer safe-output validation for agentic workflows; reviewer approval for every agentic-generated PR.
> - **New threat category — Agentic / LLM-specific:**
>   - Prompt injection via upstream political-content sources → mitigated by MCP-side input sanitisation, system-prompt hardening, and safe-outputs schema validation.
>   - Tool-call exfiltration attempts → mitigated by Squid proxy + iptables egress allow-list.
>   - Model-generated misinformation → mitigated by human-review gate (layer 4 of safe-outputs), source citation enforcement, and the AI FIRST quality principle.
>   - Covered by [OWASP LLM Security Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/OWASP_LLM_Security_Policy.md) and [AI_Policy](https://github.com/Hack23/ISMS-PUBLIC/blob/main/AI_Policy.md).
> - **New threat category — Supply-chain on MCP servers:** SBOM checks for `@jarib/pxweb-mcp`, `worldbank-mcp`, and the hosted `riksdag-regering` endpoint; version pinning; OpenSSF Scorecard on dependencies where available.
> - **Data poisoning on CIA upstream repo:** schema validation + diff review gates on every `update-cia-csv-data.yml` auto-PR.
> - MITRE ATT&CK references integrated: T1195 (Supply Chain Compromise), T1566 (Phishing — N/A no users), T1078 (Valid Accounts — OIDC-only mitigates), T1486 (Data Encrypted for Impact — immutable backups mitigate), plus ATLAS AML.T0051 (LLM Prompt Injection) and AML.T0053 (LLM Plugin Compromise).
> - Compliance mapping: ISO 27001:2022 Annex A.5.7/A.8.8/A.8.28, NIST CSF 2.0 ID.RA/DE.AE/RS.AN, CIS Controls v8.1 #16/#18, NIS2 Art. 21, EU CRA Annex I §(3).

### **🔐 Crown Jewel Analysis**

Crown Jewels are the top 5 highest-value assets that adversaries most desire and whose compromise would cause the greatest harm to Riksdagsmonitor's democratic transparency mission.

| Crown Jewel Rank | Asset | Crown Jewel Rationale | Attack Attractiveness | Compromise Impact | Protection Priority |
|-----------------|-------|----------------------|----------------------|-------------------|---------------------|
| **👑 #1** | 🗳️ **Election Data Integrity** | Accuracy of election predictions, seat forecasts, and voting record aggregation from CIA platform; any manipulation directly undermines democratic accountability | **VERY HIGH** — Nation-state actors, political adversaries, election interference campaigns | Catastrophic: Misinformation affects public understanding of Swedish democratic processes, potential election influence | **CRITICAL — Multiple overlapping controls** |
| **👑 #2** | 📊 **Dashboard Data Accuracy** | CIA platform data pipeline integrity and Chart.js/D3.js visualizations; primary channel for political transparency; 14-language real-time display | **HIGH** — Data accuracy is core mission; CSP/SRI protect against XSS/CDN tampering | High: Corrupted dashboards erode public trust, could misrepresent party standings or vote outcomes | **HIGH — SRI hashes, CSP, dual-region** |
| **👑 #3** | 🌍 **Multi-Language Content** | 14-language factual consistency (SV, EN, DA, NO, FI, DE, FR, ES, NL, AR, HE, JA, KO, ZH); translation divergence enables targeted disinformation campaigns in specific languages | **HIGH** — RTL (Arabic/Hebrew) harder to validate; targeted manipulation of specific language communities | High: Language-specific manipulation could spread unchecked; undermines trust of multilingual audience | **HIGH — TRANSLATION_GUIDE.md, Playwright RTL testing** |
| **👑 #4** | 🔑 **CI/CD Pipeline Security** | GitHub Actions OIDC, supply chain integrity, SHA-pinned actions, SLSA attestations; compromise enables persistent content injection with no trust boundary to stop it | **HIGH** — Supply chain attacks (SolarWinds-pattern) increasingly common against civic platforms | Catastrophic: Persistent backdoor in CI/CD bypasses all publication controls; could inject malicious HTML into all pages | **CRITICAL — OIDC, SHA-pinning, branch protection** |
| **👑 #5** | 📰 **News Article Credibility** | AI-generated (Claude Opus 4.7) daily political news accuracy; journalistic credibility for Swedish parliamentary and government activity reporting | **MEDIUM-HIGH** — Prompt injection, hallucination; AI-generated political misinformation campaigns | High: Fabricated parliamentary data damages reputation, could be amplified by external media; EU AI Act liability | **HIGH — Mandatory PR review, dok_id validation** |

**Crown Jewel Protection Strategy:**
- 🔐 **Defense-in-Depth:** Every Crown Jewel has ≥3 overlapping controls (no single point of failure)
- 🎯 **Zero-Tolerance Policy:** Crown Jewels #1 and #4 have CRITICAL integrity requirements — any detected compromise triggers immediate incident response
- 🔍 **Enhanced Monitoring:** Crown Jewels receive continuous automated monitoring plus human spot-checks
- 📋 **Quarterly Review:** Crown Jewel list reviewed quarterly and after any significant architectural change

| Asset | Confidentiality Goal | Integrity Goal | Availability Goal |
|-------|---------------------|----------------|-------------------|
| **Dashboard Code** | Public (open source) | **HIGH** - No unauthorized modifications | **HIGH** - 99.95% uptime |
| **Political Data** | Public (Swedish law) | **CRITICAL** - 100% accuracy required | **HIGH** - Daily updates essential |
| **Infrastructure** | Internal (AWS configs) | **HIGH** - Prevent misconfiguration | **CRITICAL** - 99.998% target |
| **AI Content** | Public (after review) | **CRITICAL** - Zero hallucinations published | **MEDIUM** - Graceful degradation OK |
| **Brand Assets** | Public (marketing) | **HIGH** - Authentic representation | **MEDIUM** - Backup channels exist |

| Trust Boundary | Crossing Point | STRIDE Threats | Key Controls |
|---------------|----------------|----------------|-------------|
| **TB-1: Internet → CloudFront** | User HTTPS requests | **S**: Domain spoofing, **T**: MITM, **D**: DDoS | TLS 1.3, HSTS, AWS Shield, Domain monitoring |
| **TB-2: Internet → GitHub Pages** | DR failover requests | **S**: Phishing sites, **T**: Content injection, **D**: GitHub outage | HTTPS, Branch protection, GitHub SLA |
| **TB-3: CloudFront → S3** | Internal AWS communication | **I**: Unauthorized access, **E**: IAM escalation | OIDC, Least privilege IAM, S3 bucket policy |
| **TB-4: GitHub Actions → AWS** | OIDC deployment | **I**: Secret exposure, **E**: Privilege escalation | OIDC (no long-lived keys), CloudTrail monitoring |
| **TB-5: GitHub Actions → Claude API** | AI content generation | **T**: Prompt injection, **I**: Hallucination, **R**: Non-determinism | Input sanitization, output validation, PR review |

### **🔪 Kill Chain Disruption Analysis**

Per [Hack23 Threat Modeling Policy § 4.1.4](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Threat_Modeling.md), mapping defensive controls to each Cyber Kill Chain phase for Riksdagsmonitor:

| Kill Chain Phase | Attacker Activity (Riksdagsmonitor Context) | Defensive Control | Detection Mechanism | Disruption Effectiveness |
|-----------------|---------------------------------------------|-------------------|---------------------|--------------------------|
| **1. Reconnaissance** | Scan public GitHub repo for secrets, enumerate AWS infrastructure, identify AI workflow schedules | Public repo accepted risk; minimal metadata exposure via `.gitignore`, S3 bucket policy, no directory listing | Repository traffic anomaly (GitHub Insights), Route 53 query logs | ⚠️ 60% — Public repo limits concealment |
| **2. Weaponization** | Craft malicious npm package, prepare XSS payload, develop AI prompt injection | N/A — occurs off-target; no direct defense | Threat intelligence feeds (ENISA, CERT-SE, MITRE ATT&CK updates) | ⚠️ 30% — Attacker-side activity |
| **3. Delivery** | Submit malicious PR, phishing for GitHub credentials, CDN asset substitution | Branch protection (PREV-002), MFA (PREV-001), SRI hashes (PREV-012), SHA-pinned Actions (PREV-015) | Dependabot alerts (DET-007), SRI failure (DET-006), CodeQL (DET-008) | ✅ 95% — Multi-layer delivery blocking |
| **4. Exploitation** | Execute XSS via CDN compromise, exploit vulnerable dependency, AI prompt injection | CSP (PREV-011), Dependabot patching (PREV-013), input sanitization (PREV-023), HTTPS-only (PREV-009) | CSP violation reports (DET-005), CodeQL findings (DET-008), PR review rejection (DET-012) | ✅ 92% — Static architecture limits exploitation |
| **5. Installation** | Persist via modified GitHub Actions workflow, inject into build pipeline | Workflow approval (PREV-016), CODEOWNERS (PREV-004), Git immutable history | Workflow execution logs (DET-009), GitHub audit logs (DET-001) | ✅ 90% — No server-side persistence possible |
| **6. Command & Control** | Covert C2 via DNS tunneling, CDN abuse for data exfiltration | Static architecture eliminates server-side C2; Route 53 monitoring | CloudTrail (DET-002), Route 53 DNS query logs | ⚠️ 70% — Limited by static-site architecture (vendor-dependent) |
| **7. Actions on Objectives** | Deface website, inject disinformation, manipulate political data, DDoS during elections | S3 versioning (PREV-019), Git revert (CORR-001), DR failover (CORR-003), mandatory PR review (PREV-028) | CloudWatch alarms (DET-004), Shield metrics (DET-010), content integrity monitoring | ✅ 97% — Rapid rollback + multi-region DR |

**Kill Chain Disruption Summary:**
- **Strongest disruption:** Phase 3 (Delivery) at 95% and Phase 7 (Actions on Objectives) at 97% — multi-layer preventive and corrective controls
- **Weakest disruption:** Phase 2 (Weaponization) at 30% — attacker-side activity, mitigated by threat intelligence
- **Architecture advantage:** Static website + no server-side code eliminates Phases 5-6 attack surface almost entirely
- **Overall Kill Chain Disruption Score:** **76%** (simple average across all phases)

| **🤝 Civil Society Trust** | Loss of transparency advocate support | HIGH - Stakeholder alienation | Incident transparency, public accountability |

### **Swedish Political Context Threats**

#### Riksdag-Specific Threats:

| Threat | Swedish Political Context | Attack Scenario | Current Controls | Gap Analysis |
|--------|---------------------------|----------------|------------------|--------------|
| **Betänkande Manipulation** | "Betänkande" (committee report) mistranslation | AI translates "betänkande" as "consideration" instead of "committee report" across 14 languages | TRANSLATION_GUIDE.md terminology dictionary | ⚠️ GAP: No automated translation validation (planned Q2 2026) |
| **Riksdagsbeslut Fabrication** | "Riksdagsbeslut" (parliamentary decision) fake records | AI hallucinates non-existent parliamentary decisions with plausible dok_id | Document ID validation (manual PR review) | ⚠️ GAP: No automated API verification (planned Q1 2026) |
| **Utskott Misattribution** | Committee ("utskott") jurisdiction errors | AI attributes motion to wrong committee (e.g., Finance instead of Foreign Affairs) | riksdag-regering-mcp organ field validation | ✅ ADEQUATE: MCP returns correct organ code |
| **Voteringsresultat Arithmetic** | Vote margin calculation errors | AI reports 175-174 vote when actual is 176-173 | Display full vote counts (not margins), PR review | ⚠️ GAP: No automated vote arithmetic validation |
| **Partirepresentation Bias** | Unequal party coverage in AI news | AI-generated articles favor specific parties (e.g., more positive language for S vs. SD) | Editorial guidelines, human review | ⚠️ GAP: No party mention tracking dashboard (planned Q2 2026) |

#### Regeringen-Specific Threats:

| Threat | Swedish Government Context | Attack Scenario | Current Controls | Gap Analysis |
|--------|----------------------------|----------------|------------------|--------------|
| **Proposition Fabrication** | Fake government propositions (prop.) | AI invents non-existent proposition with fabricated prop number | regeringen.se URL validation via g0v.se | ✅ ADEQUATE: All propositions require valid URL |
| **SOU/Ds Report Misattribution** | Government inquiry (SOU/Ds) incorrect department | AI attributes SOU report to wrong ministry | analyze_g0v_by_department validation | ✅ ADEQUATE: MCP returns correct department |
| **Ministerial Quote Fabrication** | Fake statements from Swedish ministers | AI generates quotes attributed to ministers that were never said | Source citations (g0v.se URLs), PR review | ⚠️ GAP: No automated quote verification against speech transcripts |
| **Government Document Metadata** | Incorrect document dates, departments | AI reports wrong publication date or departmental origin | get_g0v_document_content metadata validation | ✅ ADEQUATE: MCP returns structured metadata |
| **Remiss Process Misrepresentation** | Incorrect remiss (public consultation) status | AI reports closed remiss as open or vice versa | g0v.se remiss status field | ✅ ADEQUATE: MCP returns current status |

### **Democratic Accountability Metrics**

| Metric | Target | Current Performance | Monitoring Method |
|--------|--------|---------------------|------------------|
| **Factual Accuracy (Post-Review)** | 98%+ | 98-99% (estimated) | PR rejection rate tracking |

| **Cross-Language Consistency** | 90%+ | 80-85% (estimated) | Manual spot-checks (planned automation Q2 2026) |
| **Party Representation Balance** | ±5% variance | Not measured | ⚠️ GAP: Planned Q2 2026 dashboard |
| **Document ID Validation Coverage** | 100% | 100% (manual) | PR review checklist |
| **Translation Quality (Human Review)** | 90%+ | 90-95% (estimated) | TRANSLATION_GUIDE.md compliance |

### **Civic Technology Threat Scenarios**

#### Scenario: Election Day Disinformation Campaign

**Threat Actor:** Nation-State APT (Foreign Intelligence Service)  
**Timing:** Swedish parliamentary election Sunday (September 2026)  
**Attack Vector:**
1. **Pre-positioning (Weeks Before):** Compromise MCP server, inject subtle bias in AI content generation
2. **Activation (Election Day):** Publish false exit poll data, fabricate early vote counts
3. **Amplification (Social Media):** Coordinate with bot networks to spread misinformation
4. **Persistence (Post-Election):** Maintain doubt about election integrity

**Impact:**
- Erosion of public trust in Swedish election results
- International media attention questioning Swedish democracy
- Long-term reputational damage to Riksdagsmonitor
- Potential legal liability for spreading false information

**Mitigation:**
- **Pre-Election:** Freeze AI content generation 48h before election (manual mode only)
- **During Election:** Heightened human review, no automated political data publication
- **Post-Election:** Cross-verify all results with official Riksdag sources before publication
- **Incident Response:** Pre-drafted public statement, CEO accountability, transparent correction process

**Residual Risk:** **MEDIUM** (2.5/10) - Accept risk with enhanced monitoring during high-stakes events

### **PASTA Framework Integration**

PASTA (Process for Attack Simulation and Threat Analysis) provides a risk-centric, attacker-focused methodology complementing STRIDE for riksdagsmonitor's democratic mission.

| PASTA Stage | Description | Riksdagsmonitor Implementation | Output |
|-------------|-------------|-------------------------------|--------|
| **Stage I: Define Objectives** | Business and security objectives | Democratic transparency, accurate Swedish political data, 14-language access | Mission statement, business objectives |
| **Stage II: Define Technical Scope** | Application + infrastructure inventory | Static website, AI workflows, AWS CloudFront, riksdag-regering-mcp, GitHub Actions | Asset inventory (ASSET-001 to ASSET-010) |
| **Stage III: Application Decomposition** | DFD, trust boundaries, data flows | C4 architecture diagrams, STRIDE per DFD element, trust boundary documentation | Architecture diagrams, DFDs |
| **Stage IV: Threat Analysis** | Threat intelligence integration | ENISA 2024/2025 trends, MITRE ATT&CK 23 techniques, Swedish CERT-SE advisories | Threat agent profiles, MITRE mapping |
| **Stage V: Vulnerability Analysis** | Identify weaknesses per component | CodeQL static analysis, Dependabot, GitHub Secret Scanning, SRI validation | Vulnerability tracking (ATT-GAP-001/002/003) |
| **Stage VI: Attack Modeling** | Realistic attack scenarios | 9 attack trees: defacement, misinformation, CDN supply chain, AI hallucination | Attack trees with probability estimates |
| **Stage VII: Risk/Impact Analysis** | Quantify business impact | $180K cost avoidance, risk scores (0-10), ROI 682% | Risk matrix, treatment decisions |

**PASTA Applicability for Riksdagsmonitor:**
- ✅ Risk-first approach aligns with democratic mission (election integrity > financial impact)
- ✅ Business objective mapping: Transparency ↔ Integrity, Availability ↔ Access to democracy
- ✅ Attacker simulation: AI misinformation actors, nation-state APTs, hacktivists modeled
- ✅ Seven-stage completion demonstrates mature threat modeling practice

### **Trike Risk-Centric Approach**

Trike focuses on acceptable risk and security auditing, ensuring every threat has an explicit risk treatment decision — fully aligned with Hack23 ISMS policy.

| Trike Concept | Riksdagsmonitor Application | Implementation |
|---------------|----------------------------|----------------|
| **Actor → Asset → Action** model | Threat agent → Crown Jewel → Attack type mapping | 7 threat agent profiles × 5 Crown Jewels × STRIDE actions |
| **Acceptable Risk Definition** | CEO-defined risk tolerance thresholds | Risk Score ≤ 3.2/10 acceptable; 0 CRITICAL risks tolerated |
| **Threat Enumeration Completeness** | All actor-asset-action triples evaluated | 52 STRIDE threats + 18 AI/LLM threats = 70 total threat entries |
| **Permission Model** | Intended vs. implemented access rights | GitHub OIDC scopes, AWS IAM policies, MCP server access controls |
| **Risk Treatment Tracking** | Every threat has explicit treatment | 0 AVOID, 48 MITIGATE, 4 TRANSFER, 18 ACCEPT (70 threats, 100% coverage) |
| **Audit Trail** | All changes tracked to threat model | Git commit history, quarterly review schedule |

**Trike Benefits for Riksdagsmonitor:**
- ✅ Auditability: Every threat has explicit MITIGATE/TRANSFER/ACCEPT decision
- ✅ Completeness check: Actor-asset-action matrix prevents threat omissions
- ✅ Democratic accountability: CEO-level risk acceptance for all residual risks
- ✅ Continuous improvement: Risk threshold adjustments tracked over time

### **Democratic Accountability Procedures**

#### Incident Response for Published Misinformation

**Severity Classification:**

| Severity | Definition | Response Time | Public Statement Required | Example |
|----------|-----------|--------------|--------------------------|---------|
| **CRITICAL** | Completely fabricated parliamentary data published | **< 4 hours** | **Yes (CEO)** | Fake vote results, non-existent proposition |
| **HIGH** | Significant factual error with reputational impact | **< 12 hours** | **Yes (project lead)** | Wrong vote margin (175-174 vs. 176-173), misattributed committee |
| **MEDIUM** | Minor factual error, limited visibility | **< 24 hours** | **No (correction notice)** | Typo in minister name, incorrect date |
| **LOW** | Stylistic issue, translation nuance | **< 72 hours** | **No (silent correction)** | Word choice in translation, formatting inconsistency |

#### Correction Protocol:

1. **Detection:** PR reviewer, user report, or automated validation failure
2. **Classification:** Assign severity (CRITICAL/HIGH/MEDIUM/LOW)
3. **Immediate Action:**
   - **CRITICAL/HIGH:** Remove article immediately (Git revert)
   - **MEDIUM/LOW:** Mark for correction (next release cycle)
4. **Investigation:** Root cause analysis (hallucination? MCP error? reviewer oversight?)
5. **Correction:** Create corrected article version with changelog
6. **Public Statement (if required):**
   - Transparent acknowledgment of error
   - Explanation of root cause (if appropriate)
   - Preventive measures implemented
   - CEO accountability signature
7. **Prevention:** Update validation gates, reviewer training, or automated checks

#### Transparency Commitment

**Public Incident Log:** All CRITICAL and HIGH severity incidents documented in GitHub Issues (public) with:
- Incident description
- Root cause analysis
- Impact assessment
- Corrective actions
- Preventive measures
- CEO accountability statement

**Example PUBLIC Incident Disclosure:**

> **Incident #2026-001: Fabricated Vote Margin Published (2026-03-15)**
>
> **Severity:** HIGH  
> **Detection:** PR reviewer post-publication (within 6 hours)  
> **Description:** AI-generated article reported incorrect vote margin (175-174) for motion H901:23. Actual margin was 176-173.  
> **Root Cause:** AI hallucination (Claude Opus 4.7 non-determinism). Document ID was correct (H901:23), but vote arithmetic was fabricated.  
> **Impact:** Misinformation visible to ~500 users before correction. No external media amplification.  
> **Corrective Actions:**
> - Article removed within 4 hours of detection
> - Corrected version published with changelog
> - Email notification to known stakeholders
>
> **Preventive Measures:**
> - Implemented automated vote margin verification against Riksdag API (Q1 2026 accelerated)
> - Enhanced PR review checklist (vote arithmetic mandatory check)
> - Reviewer training on AI hallucination detection
>
> **Accountability:** James Pether Sörling, CEO - Full responsibility for incident and prevention.
