Interview question · Identity, OAuth & Access Control

A vendor connected to your CRM is breached and its OAuth tokens are stolen. How do SaaS-to-SaaS breaches work, and how do you respond?

Nobody broke into the CRM. An integration that customers had approved years ago simply asked for the data, with valid tokens. The scored answer treats third-party grants as identities you own.

What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

A vendor announces that OAuth tokens for its integration with your CRM were stolen and used between two dates. Your CRM admin confirms the integration has a full-access API profile, and support cases sometimes contain customers' API keys and your engineers' cloud credentials.

  1. What do you do first?
  2. What is the most urgent follow-up?
  3. What changes for every integration afterwards?
  4. How do you summarise SaaS-to-SaaS breach risk?

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.
