Show Worked Solution
  • B is correct: Encryption and regular security audits are system-level measures that protect privacy and confidentiality by securing data against unauthorised access and detecting vulnerabilities.

Other options:

  • A is incorrect: Two-step authentication is a valuable individual-level measure, not a system-wide safeguard.
  • C is incorrect: Withdrawing consent is a protection of an individual’s rights, but not a system-level technical measure.
  • D is incorrect: Updating contact details ensures accuracy of personal information but does not address privacy or confidentiality risks at the system level.
