Cybersecurity · Unit 4 · Paper 2

Securing Devices unit test

A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Paper 1 Paper 2 Paper 3

Each paper is built from this unit’s 41 terms and is the same for everyone, so a teacher can assign “Unit 4, Paper 2” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

This course has no free-response prompt tagged to this unit, so one from elsewhere in the course is used. It is still worth writing — the skill transfers.

A hospital is deciding how to protect a system that stores patient records. (a) Define the confidentiality, integrity, and availability triad, and for each element give a concrete failure that would matter in this specific setting. (b) Ransomware encrypts the records and demands payment. Identify which element of the triad is most directly attacked and justify your choice. (c) Explain why a backup strategy must include restoration testing and at least one offline or immutable copy. (d) The hospital proposes requiring a second staff member to approve any bulk export of records. Name the principle this implements and explain what class of threat it addresses that technical access controls do not.
