Indicator Verdict

Indicator verdict affects how the indicator is processed and handled in Cortex XSOAR. Assigned by reputation returned by the source with highest reliability.
An indicator’s verdict is assigned according to the verdict returned by the source with the highest reliability. In cases where multiple sources with the same reliability score return a different verdict for the indicator, the worst verdict is taken.

Source reliability
The reliability of an intelligence-data source influences the verdict of an indicator and the values for indicator fields when merging indicators.
Indicator fields are merged according to the source reliability hierarchy. This means that when there are two different values for a single indicator field, the field will be populated with the value provided by the source with the highest reliability score.
In rare cases, two sources with the same reliability score might return different values for the same indicator field. In these cases, the field is populated with the most recently provided source, unless the field is verdict. If two sources have the same reliability score and return different values for the verdict field, the worse verdict is used.
For the field types Tags and Multi-select, all values are appended, nothing is overridden.
