A Threat signal from endpoint protection (EDR, endpoint.compromised): a device this person uses was cut off the network because it is believed compromised.
Classification
- Risk domain One of 9 areas of human risk, from social engineering to readiness and response. Every signal belongs to one.
- Evidence level
- Maturity practices One capability a program performs, scored on its own: See, Understand, Act, Prove, Govern and Culture.
- Leads to The kind of breach the evidence beneath it points toward, each anchored to a Verizon DBIR or VERIS pattern or an FBI IC3 category.

How it is used
Programs count "Device quarantined or flagged compromised" per person from Endpoint protection and read it beside the other Endpoint and device signals; it feeds 0 cohorts, 0 sequences and 2 breach scenarios.
A "device quarantined or flagged compromised" record is evidence of what reaches the person (the threat side of the model). It says nothing on its own about what the person did.
