Accidental threats to data

Harm to data caused by a mistake with no intent to cause damage, such as emailing the wrong person, deleting files by accident, misconfiguring sharing or losing a device.

Part of: VCE Data Analytics - U4O2 - Cyber Security: Data Security — Module 7, ACARA Digital Technologies Years 9–10 — Cyber Security Threats and Vulnerabilities — Module 12, QCE Digital Solutions Unit 4 — Complex Digital Data Exchange Problems and Solution Requirements — Module 23

Understanding Accidental threats to data in VCE Data Analytics U4O2

What it does: Choosing the wrong recipient is a mistake that discloses data without any intent to harm, so it is an accidental threat. Accidental threats come from mistakes. The key feature is the lack of intent to cause damage. The employee made an honest mistake. Ransomware is deliberate malware, so it does not fit. Wrong sharing settings can expose data to people who should not see it, with no attacker needed. Losing a device by accident can expose any data stored on it, especially if it is not encrypted. Mistakes such as emailing the wrong person or deleting files cannot be blocked by malware scanning, so controls must address human error.

Common mistakes: The check is reversed. The email would send when the typed address does NOT match the intended one, which is how an email gets sent to the wrong person by mistake. It should be IF typed = intended THEN send. Setting confirm to 'yes' skips the question, so the file is always deleted. That makes accidental deletion easy. It should be confirm ← ask('Delete file?') so the user must confirm.

Match the Pairs

accidental threat → Harm to data caused by a mistake, with no intent to cause damage
lost device → An accidental threat where a laptop or USB drive holding data is misplaced, risking exposure
A staff member sends a file with customer details to the wrong person by choosing the wrong address in the To field → emailing the wrong person
A staff member shares a folder as 'Anyone with the link can view' when it should only be shared with the finance team → misconfigured sharing
Accidental threat = a hacker deliberately deletes files to damage the business → This describes a deliberate threat. An accidental threat has no intent to cause damage and comes from a mistake, such as a staff member deleting files by accident.

Spot the Error

Question 1
A intended ← 'sam@firm.com'
B typed ← 'sam@fim.com'
C IF typed ≠ intended THEN send
D ELSE warn user
Line C — The check is reversed. The email would send when the typed address does NOT match the intended one, which is how an email gets sent to the wrong person by mistake. It should be IF typed = intended THEN send.
Question 2
A confirm ← 'yes'
B IF confirm = 'yes' THEN
C DELETE file
D ELSE keep file
Line A — Setting confirm to 'yes' skips the question, so the file is always deleted. That makes accidental deletion easy. It should be confirm ← ask('Delete file?') so the user must confirm.
Question 3
A folder ← 'HR payroll'
B sharing ← 'public'
C SAVE settings
Line B — A confidential payroll folder is set to public by mistake (a misconfigured sharing setting). Anyone could see it. It should be sharing ← 'restricted'.
Question 4
A laptop.encrypted ← TRUE
B laptop.remoteWipe ← TRUE
C IF found THEN remote wipe
Line C — The condition is wrong. The remote wipe should run when the device is lost, not when it is found. It should be IF lost THEN remote wipe.
Question 5
A msg ← 'Marks for Ali'
B email.to ← 'year9@mail.com'
C email.body ← msg
D send email
Line B — The private marks for one student are addressed to a whole year group, so the data goes to the wrong people by mistake. It should be addressed to the intended recipient: email.to ← 'ali.dad@mail.com'.
