What this card says

Short answer

A zero-day is a vulnerability with no public patch at the time it’s found or exploited.

Example

You can’t patch it yet, so you lean on layers: least privilege, EDR behaviour detection, segmentation.

Say it in the interview

“Defence-in-depth buys time until the vendor fix lands, then I patch fast.”

Why it matters

No patch means detection and layering are your only defence for a while.
