Interview question · Detection Engineering & Incident Response

What endpoint telemetry matters most for detection and investigation on Windows and Linux, and how is it collected?

Process creation with full command line and parentage answers more questions than any other event. The rest of the answer is about the next five sources, how sensors collect them, and what attackers do to blind them.

What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

A company deploys EDR across Windows laptops and Linux servers and must decide what telemetry to collect and how to keep it trustworthy.

  1. Which endpoint events are most valuable?
  2. How do sensors collect this?
  3. Why send telemetry off-host quickly?
  4. What if an attacker tampers with the sensor?
  5. How do you manage cost and volume?
  6. What telemetry plan would you set?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Sign in free to open it.
