What if · the follow-ups in this answer

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

A company's security team must decide how much to worry about Android exploit chains for its employees' phones.

  1. What does full device compromise usually need?

  3. Who uses full chains?
  4. What reduces exposure for everyone?
  5. What extra steps for high-risk staff?
  6. What policy would you set?

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.
