Unit 2 assessment — Security levels and protection profiles

Six questions on target levels, the seven requirements, and what breaches a profile.

6 questions drawn from a bank of 11, in their own order with the options moved. Take it again and you sit a different paper.

  1. 1. A plant publishes a target of SL3 for its control zone and an achieved level of SL2. What is that gap?

  4. 4. Achieved level is measured today and target level is set by consequence. Which one moves when a new firewall is installed?

    Tests: Which level a control changes

  5. 5. Why is a claimed security level worth less without a documented threat the zone was sized against?

    Tests: What makes a level claim meaningful
