Critical and High Risks

R-1: Non-Member Access Policy Ambiguity 🔴

Category: Business
Probability: High
Impact: High
Status: ⚠️ UNRESOLVED

Description: Lack of clear business rules for granting data access to non-member subcontractors creates operational and legal uncertainty.

Potential Impact:

• Legal liability for unauthorized data sharing
• Operational delays in transport chains
• Inconsistent access decisions
• Compliance violations

Mitigation Strategy:

• Stakeholder workshop to define non-member access policy (planned)
• Legal review of liability framework
• Pilot program with selected participants
• Implement tiered access model as interim solution

Contingency Plan:

• Default to restrictive access
• Manual approval workflow
• Escalation to legal team

---

R-2: Scalability Bottlenecks 🔴

Category: Technical
Probability: High
Impact: Critical

Description: System may not scale to handle 10,000+ active participants with millions of records.

Current Bottlenecks:

• Database write throughput limits
• Event Grid capacity constraints
• Token generation performance
• Cache synchronization overhead

Mitigation Strategy:

• Implement database sharding
• Deploy read replicas
• Optimize query patterns
• Enhance caching strategy

Monitoring:

Metrics to Track:
  - Database CPU utilization
  - Query response times
  - Event processing lag
  - Cache miss rate
  - API throttling incidents

---

R-3: Security Breach 🔴

Category: Security
Probability: High
Impact: High

Description: Potential for unauthorized access to sensitive transport data through various attack vectors.

Attack Vectors:

• Token forgery or theft
• API vulnerabilities
• Insider threats
• Supply chain attacks

Mitigation Strategy:

• Regular security audits
• Penetration testing quarterly
• Security training for developers
• Implement zero-trust architecture
• Enhanced monitoring and alerting

Incident Response Plan:

1. Immediate containment
2. Impact assessment
3. Stakeholder notification
4. Forensic analysis
5. Recovery and remediation

Medium Risks

R-4: Integration Complexity 🟡

Category: Technical
Probability: High
Impact: Medium

Description: Complex integration requirements may delay adoption by transport parties.

Challenges:

• Diverse existing systems
• Varying technical capabilities
• Legacy system constraints
• Multiple data formats

Mitigation:

• Provide comprehensive SDKs
• Create integration templates
• Offer professional services
• Phased rollout approach

---

R-5: Regulatory Compliance Changes 🟡

Category: Compliance
Probability: High
Impact: Medium

Description: Evolving regulations (GDPR, NIS2, sector-specific) may require system changes.

Mitigation:

• Regular compliance reviews
• Flexible architecture design
• Legal team engagement
• Audit trail capabilities
• Maintain explicit mapping to current obligations: see NIS2 compliance mapping

Related risk: R-17 covers the specific NIS2 supply-chain liability exposure.

---

R-6: Vendor Lock-in 🟡

Category: Technical
Probability: Medium
Impact: High

Description: Heavy reliance on Azure-specific services creates vendor dependency.

Dependencies:

• Azure Kubernetes Service (AKS)
• API Management
• Document Intelligence

Mitigation:

• Abstract Azure services behind interfaces
• Document Azure-agnostic alternatives
• Maintain portability assessment
• Regular vendor review

---

R-7: Performance Degradation 🟡

Category: Technical
Probability: High
Impact: Low

Description: System performance may degrade under unexpected load patterns.

Mitigation:

• Continuous performance testing
• Auto-scaling configuration
• Performance monitoring
• Capacity planning

---

R-8: Data Quality Issues 🟡

Category: Data
Probability: Medium
Impact: Medium

Description: Poor data quality from Excel imports and manual entry affects system reliability.

Mitigation:

• Input validation rules
• Data quality monitoring
• User training programs
• Automated data cleaning

---

R-17: NIS2 Supply-Chain Liability Exposure 🟡

Category: Compliance / Commercial
Probability: High
Impact: High
Status: ⚠️ ACTIVE — gap analysis published

Description: Most CTN participants are themselves NIS2-obliged entities (Transport sector). Under Article 21(2)(d) they must perform supply-chain security assessments on their critical providers — including CTN. If CTN cannot demonstrate adequate security controls (ISO 27001, pentest reports, SBOM, CVD policy, incident response capability), participants face two equally bad options: include CTN in their attestations regardless and absorb the residual risk, or exclude CTN as a critical provider and reduce their reliance on it. Either outcome harms CTN adoption.

A separate question is whether DIL itself qualifies as a NIS2 entity under “Digital Infrastructure” or “ICT service management”. If yes, DIL faces direct supervision by RDI, mandatory registration, 24h/72h/1M incident reporting, and management-body liability with personal exposure for directors. Penalties reach €10M / 2% of worldwide turnover.

Potential Impact:

• Participant churn or refusal to onboard
• Direct regulatory exposure for DIL with personal director liability
• Reputational damage from a publicly-reported security incident without an established response process
• Penalties up to €10M / 2% of worldwide turnover

Mitigation Strategy:

• Maintain the NIS2 compliance mapping as a living document
• Pursue ISO 27001 certification for DIL operations
• Schedule annual external penetration test
• Publish vulnerability disclosure policy (security.txt) on all CTN portals
• Establish SBOM generation in CI/CD
• Document and rehearse 24h / 72h / 1M incident reporting flow
• Provide NIS2 awareness training for the DIL management body
• Obtain legal opinion on whether DIL qualifies as a NIS2 entity

Contingency Plan:

• If a participant’s NIS2 audit identifies CTN as inadequate: targeted remediation plan with documented timeline
• If RDI determines DIL is in scope: registration, board training, and rapid-track ISO 27001 program
• Maintain pre-drafted CSIRT-DSP notification templates so the 24h clock can be met from day one
