Deploy MISP (Malware Information Sharing Platform) to aggregate, correlate, and distribute threat intelligence feeds from multiple sources for centralized IOC management and automated SIEM integration.
MISP is the leading open-source threat intelligence platform for collecting, storing, distributing, and sharing cybersecurity indicators and threat intelligence. It aggregates feeds from OSINT sources, commercial providers, and sharing communities into a unified platform with automatic correlation, STIX/TAXII export, and direct integration with SIEMs and security tools. This skill covers deploying MISP via Docker, configuring feeds from sources like abuse.ch, AlienVault OTX, and CIRCL, setting up automated feed synchronization, and integrating with Splunk, Elasticsearch, and SOAR platforms.
When to Use
When deploying or configuring building threat feed aggregation with misp capabilities in your environment
When establishing security controls aligned to compliance requirements
When building or improving security architecture for this domain
When conducting security assessments that require this implementation
Prerequisites
Docker and Docker Compose for deployment
Python 3.9+ with pymisp library for API interaction
Linux server with 8GB+ RAM for production deployment
Understanding of IOC types and threat intelligence lifecycle
Network access to external feed URLs
Key Concepts
MISP Architecture
MISP stores threat intelligence as Events containing Attributes (IOCs) organized by type and category. Events can have Tags (MITRE ATT&CK, TLP marking, sector tags), Galaxies (threat actor profiles, malware families, attack patterns), and Objects (structured groupings of related attributes). Events are correlated automatically across the instance.
Feed Types
MISP supports three feed formats: MISP format (native JSON events), CSV (comma-separated IOCs), and freetext (unstructured text with automatic IOC extraction). Feeds can be remote (fetched from URLs) or local (uploaded files). MISP ships with 80+ default OSINT feeds including abuse.ch URLhaus, Botvrij, CIRCL OSINT, and malware traffic analysis.
Sharing and Synchronization
MISP instances can synchronize with other MISP instances via push/pull mechanisms. Sharing groups control distribution (organization only, this community, connected communities, all communities). The TAXII server module enables integration with STIX/TAXII consumers.
Workflow
Step 1: Deploy MISP with Docker

Step 2: Configure Feeds via PyMISP API
from pymisp import PyMISP, MISPFeed
import json
classMISPFeedManager:
def__init__(self, misp_url, misp_key, verify_ssl=False):
self.misp = PyMISP(misp_url, misp_key, verify_ssl)

Step 3: Search and Correlate Indicators

results_by_type = search_indicators(misp, type_attribute="ip-dst", last_days=7)
results_by_tag = search_indicators(misp, tags=["tlp:white", "type:OSINT"])
Step 4: Export to SIEM (Splunk / Elasticsearch)

)
if resp.status_code == 200:
exported += 1print(f"[+] Exported {exported}/{len(attributes)} indicators to Splunk")
defexport_ioc_list(self, output_file, ioc_types=None, days=30):

ioc_types = ioc_types or ["ip-dst", "domain", "hostname", "url"]
