+### [Trust - Indicators of Trust](./trust)
+
+The Trust Taxonomy provides a way to use Indicators of Trust within MISP to get insight on data about what can be trusted. Similar to a whitelist but on steroids, leveraging MISP features one would use with Inidicators of Compromise, but to filter out what is known to be good.

 ### Vocabulary for Event Recording and Incident Sharing [VERIS](./veris)
 
 Vocabulary for Event Recording and Incident Sharing is a format created by the [VERIS community](http://veriscommunity.net/).
