ICDL Cyber Security (ICDL) study guide
ICDL Cyber Security · Work through your exam, one topic at a time.
ICDL Cyber Security is one of the certification programmes offered by ICDL Foundation, a global social enterprise that describes itself as committed to raising standards of digital competence in the workforce, education and society, with certification available in more than 100 countries. The credential sits within the ICDL CORE family, which ICDL positions as core digital skills for employability and productivity, so it suits students, job-seekers and working professionals who need to demonstrate practical security awareness rather than deep technical engineering skill. Candidates typically study four areas: cyber security concepts (why data, systems and identities need protection, and the value of information), threats and risks (phishing, malware and identity theft among them), protecting data and devices (passwords, updates, backups and safe configuration), and safe, responsible online behaviour. Because the syllabus is practical and scenario-based, the best preparation is hands-on: practise recognising suspicious messages, review the security settings on your own devices and accounts, and work through practice questions until the reasoning behind each answer is clear. The ICDL Cyber Security study guide has 4 sections and about 1,178 words.
01Cyber Security Concepts
Cyber security is the practice of protecting information and the systems that hold it from unauthorised access, change, loss, or disruption. Understand the CIA triad : confidentiality (only authorised people can read data), integrity (data is accurate and unaltered), and availability (data and services are reachable when needed).

Learn to recognise the main categories of attack and the social engineering behind them. Malware is an umbrella term: viruses attach to files and need user action; worms self-replicate across networks; trojans disguise themselves as legitimate software; ransomware encrypts data and demands payment; spyware covertly collects information; keyloggers record keystrokes.
