Question 310
The business insists on strongest possible encryption without understanding operational recovery impact. Which decision is BEST supported by the business and security evidence?
Explanation
Correct Answer
Control requirements must support all applicable business and security properties. This directly meets the requirement to balance encryption with service resilience.
Incorrect Answers
Complementary layers reduce reliance on one possibly failing defense. That action would design defense in depth for critical processes; it does not address the case's priority to balance encryption with service resilience.
Controls should address specific risks with measurable performance. This would help derive monitoring needs from threat scenarios; the scenario instead requires a decision to balance encryption with service resilience.
Proportionate controls focus assurance where the consequences justify it. That action would risk-tier security control requirements; it does not address the case's priority to balance encryption with service resilience.
