Test: 1. Feed onboarding: Can your top 5 feeds be ingested within 4 hours? 2. SIEM integration: Can enriched IOCs push to your SIEM in <5 minutes? 3. ATT&CK mapping: Can analysts tag indicators with ATT&CK techniques efficiently? 4. Report generation: Can the platform produce a tactical IOC bulletin with one click? 5. API performance: Can the REST API handle 10,000 indicator queries per day? ### Step 4: Score and Select Use weighted scoring matrix (weight each criterion by organizational priority): ``` Criterion Weight Vendor A Vendor B STIX 2.1 compliance 20% 95 85 SIEM integration 25% 90 70 ATT&CK mapping 15% 85 95 Cost (inverse) 20% 60 90 UI/analyst experience 10% 80 75 Vendor support quality 10% 85 80 TOTAL 100% 82.0 81.5 ``` ### Step 5: Implementation and Onboarding Planning Plan 90-day implementation: - Week 1–2: Infrastructure deployment (cloud or on-prem) - Week 3–4: Feed onboarding and deduplication tuning - Week 5–6: SIEM/SOAR integration and testing - Week 7–8: Analyst workflow configuration and training - Week 9–12: Operational validation and go-live ## Key Concepts | Term | Definition | |------|-----------| | **TIP** | Threat Intelligence Platform — software for collecting, processing, analyzing, and disseminating cyber threat intelligence | | **TAXII Server** | Component of a TIP that serves STIX bundles to consuming systems on request | | **TC Exchange** | ThreatConnect's commercial marketplace for pre-built feed integrations and app connectors | | **Multi-tenancy** | TIP capability to serve multiple organizational units or customers with isolated data environments | | **Deduplication** | Process of identifying and merging duplicate indicators within a TIP to reduce analyst noise | ## Tools & Systems - **MISP**: Open-source TIP used by 6,000+ organizations; strongest ISAC/government community integration - **OpenCTI**: Modern open-source TIP with native STIX 2.1 and graph-based analysis - **ThreatConnect**: Enterprise commercial TIP with lifecycle management and SOAR playbook integration - **Anomali ThreatStream**: Commercial TIP with strong Splunk ecosystem integration - **EclecticIQ**: Commercial TIP with ATT&CK-centric workflow design ## Common Pitfalls - **Selecting TIP before defining requirements**: Technology selection before use case definition leads to expensive mismatches. - **Underestimating administration burden**: MISP and OpenCTI require dedicated admin time (minimum 0.25 FTE); budget accordingly. - **Ignoring data migration costs**: Moving historical intelligence from one TIP to another is costly and often impractical for legacy systems. - **Not testing SIEM integration in PoC**: TIP value depends heavily on downstream integration quality; always test SIEM/SOAR connectivity during evaluation. ## Other files in this skill - [LICENSE](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/evaluating-threat-intelligence-platforms/LICENSE) - [references/api-reference.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/evaluating-threat-intelligence-platforms/references/api-reference.md) - [scripts/agent.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/evaluating-threat-intelligence-platforms/scripts/agent.py) ## references/api-reference.md (verbatim) # Threat Intelligence Platform Evaluation API Reference ## MISP REST API ```bash # Get version curl "https://misp.example.com/servers/getVersion.json" \ -H "Authorization: YOUR_API_KEY" -H "Accept: application/json" # Search events curl -X POST "https://misp.example.com/events/restSearch" \ -H "Authorization: YOUR_API_KEY" -H "Content-Type: application/json" \ -d '{"tags": ["apt28"], "limit": 50}' # Export STIX 2.1 curl "https://misp.example.com/events/restSearch" \ -H "Authorization: YOUR_API_KEY" -H "Accept: application/json" \ -d '{"returnFormat": "stix2"}' # Feed management curl "https://misp.example.com/feeds/index.json" -H "Authorization: YOUR_API_KEY" ``` ## OpenCTI GraphQL API ```graphql # Get platform version query { about { version } } # Search indicators query { indicators(filters: { key: "pattern_type", values: ["stix"] }) { edges { node { name pattern valid_from valid_until } } } } # Get campaigns query { campaigns(first: 20, orderBy: created_at, orderMode: desc) { edges { node { name first_seen last_seen objectLabel { value } } } } } ``` ## ThreatConnect REST API ```bash # List indicators curl "https://api.threatconnect.com/v3/indicators" \ -H "Authorization: TC :" # Create indicator curl -X POST "https://api.threatconnect.com/v3/indicators" \ -H "Content-Type: application/json" \ -d '{"type":"Host","hostName":"evil.example.com","rating":5,"confidence":80}' ``` ## TAXII 2.1 API ```bash # Discovery curl https://taxii.example.com/taxii2/ -H "Accept: application/taxii+json;version=2.1" # Get API roots curl https://taxii.example.com/api1/ -H "Accept: application/taxii+json;version=2.1" # List collections curl https://taxii.example.com/api1/collections/ -H "Accept: application/taxii+json;version=2.1" # Get objects from collection curl "https://taxii.example.com/api1/collections/{id}/objects/" \ -H "Accept: application/stix+json;version=2.1" ``` ## TIP Evaluation Criteria Weights | Category | Criterion | Weight | |----------|-----------|--------| | Core | STIX 2.1 support | 10 | | Core | REST API | 9 | | Core | TAXII server | 8 | | Core | TLP enforcement | 8 | | Integration | SIEM integration | 9 | | Integration | Feed ingestion | 8 | | Integration | EDR integration | 7 | | Operations | Sharing (ISAC) | 7 | | Operations | Analyst workflow | 7 | | Operations | Reporting | 6 | ## Platform Comparison Matrix | Feature | MISP | OpenCTI | ThreatConnect | |---------|------|---------|---------------| | License | Open Source | Open Source | Commercial | | STIX 2.1 | Native | Native | Import/Export | | TAXII 2.1 | Yes | Yes | Yes | | ATT&CK | Plugin | Native | Module | | Graph Viz | Basic | Advanced | Advanced | | SOAR | API | Connectors | Playbooks | Back to [[skills-anthropic-cybersecurity-skills]] or [[agent-skills]].
