Automated Indicator Sharing (AIS) Scoring Framework Used for Indicator Enrichment

CISA uses the AIS Scoring Framework to provide an opinion value for each Indicator object submitted to AIS and will also use it when CISA provides a confidence score on CISA-published Indicator objects. Together, these enrichments can help those receiving information from AIS prioritize actioning and investigating Indicator objects. This document describes methodology to explain how CISA develops opinion values and confidence scores for individual Indicator objects when provided, and so other organizations can decide whether to use the same methodology in developing their own opinion values and confidence scores.
