The STIX Language intends to convey the full range of potential cyber threat information and strives to be fully expressive, flexible, extensible, and automatable. STIX does not only allow tool-agnostic fields, but also provides so-called <i>test mechanisms</i> that provide means for embedding tool-specific elements, including OpenIOC, Yara and Snort.
The Trusted Automated eXchange of Indicator Information (TAXII) standard defines a set of services and message exchanges that, when implemented, enable sharing of actionable cyber threat information across organization and product/service boundaries. TAXII defines concepts, protocols, and message exchanges to exchange cyber threat information for the detection, prevention, and mitigation of cyber threats.
The Vocabulary for Event Recording and Incident Sharing (VERIS) is a set of metrics designed to provide a common language for describing security incidents in a structured and repeatable manner. VERIS is a response to one of the most critical and persistent challenges in the security industry - a lack of quality information. In addition to providing a structuref format, VERIS also collects data from the community to report on breaches in the Verizon Data Breach Investigations Report (<atarget="_blank"href="http://www.verizonenterprise.com/DBIR/">DBIR</a>) and publishes this database online at <atarget="_blank"href="http://vcdb.org/index.html">VCDB.org</a>.
CRITS is a platform that provides analysts with the means to conduct collaborative research into malware and threats. It plugs into a centralized intelligence data repository, but can also be used as a private instance.
The Collective Intelligence Framework (CIF) allows you to combine known malicious threat information from many sources and use that information for IR, detection and mitigation. Code available on <ahref="https://github.com/csirtgadgets/massive-octo-spice"target="_blank">GitHub</a>.
IntelMQ is a solution for CERTs for collecting and processing security feeds, pastebins, tweets using a message queue protocol. It's a community driven initiative called IHAP (Incident Handling Automation Project) which was conceptually designed by European CERTs during several InfoSec events. Its main goal is to give to incident responders an easy way to collect & process threat intelligence thus improving the incident handling processes of CERTs.
IOC Bucket is a free community driven platform dedicated to providing the security community a way to share quality threat intelligence in a simple but efficient way. The IOCs are developed by the community, reviewed by the community, and distributed for use by the community. The content will always remain free and available. In addition to searching and uploading IOCs, it also features an online IOC editor.
The Model-based Analysis of Threat Intelligence Sources (MANTIS) Cyber Threat Intelligence Management Framework supports the management of cyber threat intelligence expressed in various standard languages, like STIX and CybOX. It is *not* ready for large-scale production though.
The Malware Information Sharing Platform (MISP) is an open source software solution for collecting, storing, distributing and sharing cyber security indicators and malware analysis.
