Subject: Computer Science
Lesson Topic: Explain the difference between the terms security, privacy and integrity of data
Learning Objective/s:
  • Describe the concepts of data security, privacy, and integrity.
  • Differentiate between security, privacy, and integrity in terms of purpose and primary concerns.
  • Explain how the three concepts interrelate in real‑world data protection.
  • Apply examples of security, privacy, and integrity to illustrate their distinct roles.
  • Evaluate a simple scenario to identify which controls address each concept.
Materials Needed:
  • Projector or interactive whiteboard
  • Slides with definitions and comparison table
  • Handout containing a Venn‑diagram template
  • Case‑study cards (bank, e‑commerce, hospital)
  • Sticky notes or digital polling tool for quick checks
 Introduction:

Begin with a quick think‑pair‑share where students write what “security”, “privacy”, and “integrity” mean to them. Highlight common misconceptions and link to prior lessons on data handling. State that by the end of the lesson they will be able to clearly distinguish and connect these three essential concepts.
Lesson Structure:
  1. Do‑now (5') – Students list definitions on sticky notes; brief whole‑class share.
  2. Direct instruction (10') – Present concise definitions and primary concerns using slides.
  3. Comparison activity (10') – In pairs, fill a three‑column table (term, definition, concern) and discuss differences.
  4. Interrelation discussion (8') – Whole‑class explore how security supports privacy and integrity, referencing the three overlap points.
  5. Real‑world examples (10') – Groups examine case‑study cards, identify which concept each example illustrates, and justify their choices.
  6. Diagram construction (7') – Students add their examples to a Venn diagram on the handout.
  7. Check for understanding (5') – Quick quiz or exit ticket where learners classify three statements as security, privacy, or integrity.
Conclusion:

Summarise the distinct roles of security, privacy, and integrity and how they overlap in protecting data. Collect the exit tickets to gauge individual understanding, and assign a short homework task: students must find a news article and label which of the three concepts is most relevant.
