MISP
MISP — Open Source Threat Intelligence Platform
Offene Threat-Intelligence-Sharing-Plattform
MISP is an open platform for collecting, structuring and sharing threat information — in particular indicators such as malicious IP addresses, domains or file hashes. It enables organisations to exchange insights about attacks among one another in a trust-based, machine-readable way. In the CERT and SOC world, MISP is one of the most widely used building blocks of threat intelligence.
History & facts. MISP grew out of the practice of defenders who observed that attackers reuse infrastructure and tools — shared knowledge about indicators therefore yields a collective advantage. The platform organises information into events and attributes, augments them with taxonomies and so-called galaxies (e.g. for attributing actors) and controls precisely who may see what via sharing groups. Exchange is machine-readable and can be connected to detection systems.
Outlook & recommendation. Threat intelligence only realises its value collectively: a single incident at one member can forewarn many others. Discipline with confidentiality levels matters — the TLP model governs how far information may be passed on. MISP indicators can be fed into a SIEM or an intelligence platform and correlated there with one's own telemetry.
