Interview question · Detection Engineering & Incident Response

Design a security telemetry pipeline for millions of events per second that supports detection and survives an attacker.

A logging pipeline is a distributed system with a threat model: attackers want it blind, analysts want it fast, finance wants it cheap. The staff answer designs for all three and for the day the queue backs up.

What if · the follow-ups in this answer

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

A company ingests terabytes of security logs a day into a SIEM, and during a recent incident authentication events were delayed by hours behind debug logs.

  1. How should collection work?
  2. Where do normalisation and detection run?
  3. How do you stop debug logs delaying authentication events?
  4. How do you store terabytes affordably?
  5. How do you protect the pipeline's integrity?
  6. How would you design the pipeline?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
