# CTI This repository contains the MITRE ATT&CK® and CAPEC™ datasets expressed in STIX 2.0. See [USAGE](USAGE.md) or [USAGE-CAPEC](USAGE-CAPEC.md) for information on using this content with [python-stix2](https://github.com/oasis-open/cti-python-stix2). If you are looking for ATT&CK represented in STIX 2.1, please see the [attack-stix-data](https://github.com/mitre-attack/attack-stix-data) GitHub repository. Both MITRE/CTI (this repository) and attack-stix-data will be maintained and updated with new ATT&CK releases for the foreseeable future, but the data model of attack-stix-data includes quality-of-life improvements not found on MITRE/CTI. Please see the [attack-stix-data USAGE document](https://github.com/mitre-attack/attack-stix-data) for more information on the improved data model of that repository. ## ATT&CK MITRE ATT&CK is a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations. The ATT&CK knowledge base is used as a foundation for the development of specific threat models and methodologies in the private sector, in government, and in the cybersecurity product and service community. ## CAPEC Understanding how the adversary operates is essential to effective cyber security. CAPEC™ helps by providing a comprehensive dictionary of known patterns of attacks employed by adversaries to exploit known weaknesses in cyber-enabled capabilities. It can be used by analysts, developers, testers, and educators to advance community understanding and enhance defenses. - Focuses on application security - Enumerates exploits against vulnerable systems - Includes social engineering / supply chain - Associated with Common Weakness Enumeration (CWE) ## STIX Structured Threat Information Expression (STIX™) is a language and serialization format used to exchange cyber threat intelligence (CTI). STIX enables organizations to share CTI with one another in a consistent and machine readable manner, allowing security communities to better understand what computer-based attacks they are most likely to see and to anticipate and/or respond to those attacks faster and more effectively. STIX is designed to improve many different capabilities, such as collaborative threat analysis, automated threat exchange, automated detection and response, and more.
