# Standards and Frameworks Reference
|
|
|
|
## MISP Standards
|
|
|
|
### MISP Core Format
|
|
- **MISP JSON Format**: Native event format used for synchronization between instances
|
|
- **MISP Galaxy**: Cluster-based knowledge base linked to MITRE ATT&CK, threat actors, tools
|
|
- **MISP Taxonomies**: Machine-readable tagging schemes (TLP, PAP, admiralty-scale, OSINT)
|
|
- **MISP Warninglists**: Lists of well-known indicators to reduce false positives (Alexa Top 1M, Office 365 IPs)
|
|
|
|
### STIX 2.1 (Structured Threat Information Expression)
|
|
- Standard language for representing cyber threat intelligence
|
|
- MISP supports import/export of STIX 2.1 bundles
|
|
- Object types: Indicator, Malware, Threat Actor, Attack Pattern, Campaign, Observed Data
|
|
- Relationship types: uses, targets, attributed-to, indicates, mitigates
|
|
|
|
### TAXII 2.1 (Trusted Automated Exchange of Intelligence Information)
|
|
- Transport protocol for sharing CTI over HTTPS
|
|
- MISP can consume TAXII feeds and serve as a TAXII server
|
|
- Collection-based model: discovery, API root, collections, objects
|
|
- Supports pagination and filtering by added_after, type, version
|
|
|
|
## MITRE ATT&CK Integration
|
|
- MISP Galaxy clusters map directly to ATT&CK techniques (T-codes)
|
|
- Events can be tagged with ATT&CK tactics: Initial Access, Execution, Persistence, etc.
|
|
- ATT&CK Navigator integration for visualizing technique coverage
|
|
- Sub-technique support (e.g., T1566.001 - Spearphishing Attachment)
|
|
|
|
## Traffic Light Protocol (TLP)
|
|
- **TLP:CLEAR** (formerly TLP:WHITE): Unlimited disclosure
|
|
- **TLP:GREEN**: Limited disclosure within community
|
|
- **TLP:AMBER**: Limited disclosure within organization
|
|
- **TLP:AMBER+STRICT**: Restricted to organization only
|
|
- **TLP:RED**: Restricted to specific recipients only
|
|
|
|
## Permissible Actions Protocol (PAP)
|
|
- **PAP:RED**: Only passive actions (no external lookups)
|
|
- **PAP:AMBER**: Active actions allowed but not against infrastructure
|
|
- **PAP:GREEN**: Active actions allowed
|
|
- **PAP:CLEAR**: Unlimited use
|
