Show answer
Answer
- C Block USB ports and restrict software with an allow list
- D Document the residual risk and plan the replacement
- E Separate the computer from the office network and allow only necessary connections

If an upgrade is not possible, the system is isolated and hardened: segmentation, application control, blocked interfaces. An unauthorized update can jeopardize the manufacturer's approval and operations. The remaining risk is consciously accepted and documented.
