Indicator Verdict

Learn how indicator verdicts work in Cortex XSOAR 6.13.

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.

Indicator verdicts

Indicators are assigned a verdict on a scale of 0 to 3.

Score	Verdict	Color
0	Unknown	Gray
1	Benign	Green
2	Suspicious	Orange
3	Malicious	Red

Note

You can change the benign verdict by editing the indicator. If you have manually changed the indicator’s verdict and want to recalculate it according to enrichment integrations, click Calculate when editing the indicator.

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.

Source reliability hierarchy also determines which custom indicator field mapping is used. The system uses the custom indicator field mapping from the integration instance with the highest source reliability score. To prioritize a specific mapping, ensure its integration instance has the highest source 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.

Source	Reliability Score	Notes
Manual	A+++	A user manually updates the verdict of an indicator.
Reputation script	A++	A script with the reputation tag, which calculates the verdict of an indicator.
Third-party enrichment	A+	An integration or service that evaluates the verdict of an indicator. For example, the urlscan.io integration evaluates the verdict of a URL.
Feed	A: Completely reliable	The feed reliability is applied at the integration instance level.
Feed	B: Usually reliable	The feed reliability is applied at the integration instance level.
Feed	C: Fairly reliable	The feed reliability is applied at the integration instance level.
Feed	D: Not usually reliable	The feed reliability is applied at the integration instance level.
Feed	E: Unreliable	The feed reliability is applied at the integration instance level.
Feed	F: Reliability cannot be judged	The feed reliability is applied at the integration instance level.

Example 1

In this example, two third-party integrations, VirusTotal and AlienVault, return a different verdict for the same indicator. The indicator’s verdict will be Malicious because VirusTotal’s reliability score is higher than AlienVault.

Integration	Reliability	Verdict	Final Verdict
VirusTotal	C - Fairly reliable	Malicious	Malicious
AlienVault	D- Not usually reliable	Benign	Malicious

Example 2

In this example, two sources with the same verdict score return a different verdict for the same indicator. The indicator’s verdict will be Malicious because when two sources have the same reliability, the worse verdict applies.

Integration	Reliability	Verdict	Final Verdict
TAXII Feed	B - Usually reliable	Malicious	Malicious
CSV Feed	B - Usually reliable	Benign	Malicious
