This module covers how people keep data and systems safe, and how technology affects people. It sits within IGCSE ICT and links to the practical work you do on documents and files. Check the Cambridge IGCSE ICT 0417 syllabus page for the current wording.
What should you know before you start?
You should be comfortable with basic ideas such as files, folders, user accounts and the internet. No programming is needed. If you can describe what a password does and why people save files, you are ready.
One worked example to orient you
Here is an invented case. Bright Steps Tuition Room (fictional) keeps a spreadsheet of pupil names and parents’ phone numbers on a shared computer. Anyone who sits at that computer can open it.
Risk: personal data could be seen or copied by someone who should not have it.
Control: give the file a password, and give each staff member their own login so access can be checked.
Link to recovery: if the computer fails, the spreadsheet is lost, so a second copy kept elsewhere is also needed.
Notice the pattern: data, risk, control, reason. Every lesson in this module trains that pattern on a different case.
In what order should you study the lessons?
- Identify a data-protection risk in a fictional case: start with the data and who could misuse it.
- Explain a backup and recovery distinction: then handle the risk of losing data.
- Compare authentication controls conceptually: learn how a system decides who gets in.
- Recognise accessibility requirements in a document: shift to making documents usable for everyone.
- Discuss societal effects descriptively without political endorsement: finish with balanced written discussion.
Which traps catch students most often?
- Writing “hackers” as the answer to every question, instead of the specific risk in the case.
- Mixing up backup (making a copy) and recovery (getting data back).
- Calling a control “safe” without saying what it stops.
- Giving a personal opinion in a discussion question when the task asks for effects on people.
How should you use the practice set?
Attempt the safety, security and effects practice set after the lessons, writing full answers before opening the working. The ICT practical task and evidence checker helps you check that your files and notes meet a brief, and the mistake log turns each slip into a retest.
If your answers still say “it is not safe” without naming the risk, a teacher can go through them line by line in online one-to-one ICT tuition.
