Sample ICDL Cyber Security Practice Questions

Try these sample questions to test your ICDL Cyber Security exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 118+ question experience with AI tutoring.

1A Dublin accounting firm stores client tax records on a server that only authorised staff can open. Which information-security goal does restricting access primarily support?
A.Confidentiality
B.Integrity
C.Availability
D.Portability
Explanation: Confidentiality means information is disclosed only to authorised people. Limiting who can open client records protects sensitive data from unauthorised viewing, which is the core confidentiality control in everyday office practice.
2After a power glitch, a payroll spreadsheet shows incorrect overtime totals that no one edited manually. Which pillar of the CIA triad has been affected?
A.Confidentiality
B.Integrity
C.Availability
D.Authentication
Explanation: Integrity ensures data remains accurate and trustworthy. Corrupted totals that were not intentionally changed indicate a loss of data integrity, even though the file may still be confidential and available.
3A flood disables the server room at a regional hospital, preventing clinicians from accessing patient scheduling software for two days. Which security principle is chiefly compromised?
A.Confidentiality
B.Integrity
C.Availability
D.Non-repudiation
Explanation: Availability means authorised users can access systems and data when required. Physical disaster blocking access is a classic availability failure, addressed through disaster recovery and off-site backups.
4An employee at an Irish SME accidentally attaches the wrong customer list to a marketing email. How should this incident be classified in the ICDL threat landscape?
A.Malicious act
B.Technical failure
C.Force majeure
D.Human error
Explanation: The syllabus groups threats into malicious acts, human error, technical failures, and force majeure. Sending the wrong attachment is an accidental mistake by an authorised user, which is human error.
5Which scenario best illustrates a force majeure threat to organisational data?
A.A wildfire destroys an on-site backup tape library
B.An intern shares passwords in a group chat
C.Outdated antivirus fails to detect ransomware
D.A competitor launches a targeted phishing campaign
Explanation: Force majeure refers to natural or environmental disasters beyond normal control. Fire destroying physical media is an environmental catastrophe, mitigated through off-site backups and disaster recovery planning.
6A caller pretending to be from your bank asks for your online banking PIN to 'verify suspicious activity.' What attack category does this represent?
A.Brute-force attack
B.Social engineering
C.SQL injection
D.Denial of service
Explanation: Social engineering manipulates people into revealing information or taking unsafe actions. Phone-based impersonation (vishing) exploits trust and urgency rather than technical exploits.
7Under the EU General Data Protection Regulation (GDPR), which right allows an individual to request that inaccurate personal data be corrected?
A.Right to erasure
B.Right to portability
C.Right to rectification
D.Right to object
Explanation: The right to rectification lets data subjects have inaccurate personal data corrected. GDPR privacy principles appear in the Cyber Security syllabus under security concepts and personal security.
8A company's Acceptable Use Policy states that work laptops must not be used to download unlicensed software. What is the primary purpose of such a policy?
A.Replace the need for antivirus software
B.Encrypt all email automatically
C.Guarantee 100% network uptime
D.Define permitted and prohibited ICT behaviour for users
Explanation: Acceptable Use Policies set clear rules for how employees may use organisational ICT, reducing risky behaviour and supporting legal and security compliance.
9Which practice best reduces identity theft risk when disposing of an old smartphone that stored banking apps?
A.Perform a factory reset and remove the SIM before recycling
B.Leave the SIM installed so the carrier can trace it
C.Place the phone in household waste without wiping
D.Sell the device online with all accounts still logged in
Explanation: Identity theft prevention includes securely erasing personal data before disposal. Factory reset removes local data; removing the SIM prevents number misuse.
10Why does the ICDL syllabus recommend disabling macros in documents from unknown senders?
A.Macros always corrupt the formatting of Word documents
B.Macros can execute code that installs malware when the file is opened
C.Macros prevent files from being password-protected
D.Macros block HTTPS connections in web browsers
Explanation: Malicious macros can run scripts that download or execute malware. Disabling macros from untrusted sources is a key file-security control taught in Security Concepts.

About the ICDL Cyber Security Exam

The ICDL Cyber Security module (successor branding to IT Security) is a Workforce-level certification offered in Ireland through ICDL Accredited Test Centres under the ICDL Foundation programme co-founded by ICS in 1997. It teaches concepts and skills for the secure use of ICT in daily life: protecting information and data, defending computers and networks from malware, using firewalls and wireless security, browsing the web safely, securing email and social communications, and backing up or securely disposing of data and devices. The official certification test contains 36 multiple-choice questions over 45 minutes with a pass mark of 75% (27/36), aligned to ICDL Cyber Security Syllabus Version 3.0. QQI has mapped ICDL certification to the National Framework of Qualifications, allowing candidates to use completed modules as exemptions toward many further-education awards.
