SYLLABUS TOPIC: SECURITY AND ETHICS, UNHU/UBUNTU (Syllabus page 23)
SUB- TOPIC: DATA PROTECTION MEASURES
CALA TYPE: PRACTICAL INVESTIGATION
DURATION: 2 WEEKS

BACKGROUND
Often the issue of data security is taken for granted in most schools. In most schools’ computer
laboratories and school offices there are inadequate data security measures to protect the valuable
personal data stored in computer systems. You are required to investigate the data security risks
for your school’s computer laboratory and administration offices and submit your findings.

The CALA has two parts, namely Activity 1 an Activity 2. You are advised to do both parts.
ACTIVITY 1
• Inspect the school’s computer lab and the school administration offices and identify all
the data security risks.
• Identify all the possible remedies for the data security risks identified.

ACTIVITY 2
• Do a cost analysis for each possible remedy identified in Activity 1.
• Write a detailed report to your school’s administration on the data security issues
affecting the computer laboratory and the school’s administration offices and suggest
recommendations that can be implemented based on your cost analysis.
HOW WILL THE LEARNER BE ASSESSED?
ACTIVITY 1
• Conducting detailed research
• Explaining in detail all the data security risks
• Identifying all the possible remedies for the data security risks identified

ACTIVITY 2

Page 3 of 6
 • Costing all the possible remedies for the data security risks identified.
• Writing a detailed report with recommendations.
LEARNER CALA TIP
• Ensure your risks are clearly explained and not just a summary of points.
