The US Cybersecurity and Infrastructure Security Agency (CISA) has released Decider, a free and open source tool designed to help defenders map attacker behavior to the Mitre ATT&CK framework. Developed in partnership with the Homeland Security Systems Engineering and Development Institute (HSSEDI) and Mitre, Decider makes the mapping process easier by asking the user a series of questions about the adversary’s activity in their network. It also provides search and filtering functionality, and allows users to export the results to common formats.
The Mitre ATT&CK knowledge base of adversary tactics, techniques and procedures (TTPs) helps security professionals understand adversary behavior. It can be useful for assessing security tools, identifying defense gaps, hunting for threats, and validating mitigation controls. However, CISA learned that many stakeholders have difficulties mapping hacker behavior to ATT&CK. That is why it has developed Decider. The tool uses simplified language to guide the user through a decision tree format, helping them pick the correct technique or subtechnique. It also provides information on potentially incorrect mappings and similar techniques to ensure accuracy.
CISA has published a fact sheet and a blog post to help defenders get started with Decider. The tool is available on GitHub, but since it’s a web application it must be hosted somewhere before it can be used. Decider is compatible with Enterprise ATT&CK 11.0 and 12.0.
In conclusion, the US Cybersecurity and Infrastructure Security Agency (CISA) has released Decider, a free and open source tool designed to help defenders map attacker behavior to the Mitre ATT&CK framework. Developed in partnership with the Homeland Security Systems Engineering and Development Institute (HSSEDI) and Mitre, Decider simplifies the mapping process and provides search and filtering functionality. CISA has published a fact sheet and a blog post to help defenders get started with the tool.
