Distinguish between the three objectives using everyday examples from their own use of computers, phones, and mobile money.
Analyse scenarios involving school, home, or business computer use to identify which security objective is being protected or violated.
Justify why the three objectives are equally important in designing security measures for an organisation.
Discuss, in groups, the consequences of failing to protect each objective and propose simple protective practices for each.
