Implementing digital examinations in free software systems
summary
Debian‑based school OS boots from USB now for secure exams but national exams have been fully digital for five years and the plan is to move from USB to a cross‑platform exam app that supports Windows Mac and managed Chromebooks but not Linux. The system in use runs on about 20% of Finnish upper secondary laptops roughly 10,000 machines and risks being displaced. Proposed defenses are signed kernel, TPM‑unlocked keys, DM‑verity/DM‑integrity plus sandboxing with bubblewrap or Tomoyo and optional monitoring (screenshots and keystroke capture). Free software claims it can meet or exceed these measures.
