Assess whether the incident is contained or still lateral from insider exfil

SITUATION An EDR agent uninstalled on the domain controller put insider exfil of a customer export in front of CISO briefing officer in a university after a research-lab GPU cluster alert. This Cybersecurity / Incident Response decision is the incident is contained from insider exfil of a customer export, and the live options are The incident is contained, Still lateral.

DECISION CISO briefing officer in a university after a research-lab GPU cluster alert must choose The incident is contained / Still lateral using insider exfil of a customer export after an EDR agent uninstalled on the domain controller.

HYPOTHESES TO TEST 1. An EDR agent uninstalled on the domain controller is noise around an already-controlled Incident Response process in a university after a research-lab GPU cluster alert, given insider exfil of a customer export. 2. An EDR agent uninstalled on the domain controller is the event in insider exfil of a customer export that forces The incident is contained for CISO briefing officer under Cybersecurity. 3. Insider exfil of a customer export shows a one-file miss after an EDR agent uninstalled on the domain controller, not a Incident Response program failure. 4.

ANALYSIS REQUIRED 1. Check SIEM or identity logs in insider exfil of a customer export for reuse after an EDR agent uninstalled on the domain controller. 2. Separate a scoped exception from an unbounded exposure a university after a research-lab GPU cluster alert has not measured. 3.
