How to use this volume
Solve the paper first, under exam conditions and against the clock. Then read the answers here and mark your own. Reading a solution before attempting the question feels productive and teaches very little, because recognising an answer is not the same as being able to write one.
SECTION I
1.
Attempt any three of the following · 15 Marks
a.Write a short note on importance of Information Protection.[5]
Answer
For full marks, cover: information as an asset, the three properties protection keeps (confidentiality, integrity, availability), what is at stake if protection fails (money, law, reputation, operations, people), a worked loss estimate, and why protection must be continuous.
Information is an asset
Every organisation runs on information: customer records, accounts, designs, plans, student marks, medical files. Much of it exists only in digital form. It has value to the organisation, and often to criminals and competitors too. Protecting it is therefore as important as protecting money or buildings.
What protection keeps
- Confidentiality: only authorised people can read it.
- Integrity: it is accurate and changed only in authorised ways.
- Availability: it can be used when needed.
Protection also keeps accountability (actions can be traced to a person) and authenticity (data and senders are genuine).
What is at stake
1. Money. Theft of funds, fraud, ransom demands, the cost of investigating and recovering, and lost business while systems are down.
2. Law and contracts. Organisations must protect personal and financial data under data protection laws and contracts. Failure can bring penalties, compensation claims and lost contracts.
3. Reputation and trust. Customers leave a company that leaks their data; students and parents lose trust in a college whose results are tampered with.
4. Operations. Ransomware or a failed server can stop billing, production or admissions for days.
5. Competitive position. Stolen designs, prices or plans help competitors.
6. People's safety and privacy. Leaked medical or location data can harm individuals directly.
Worked figure: a loss estimate
A college's server holding 20,000 student records is breached. Suppose, as an illustration, that notifying students, investigating and repairing cost Rs 1,500 per record. The admission portal is also down for 3 days, losing Rs 2,00,000 of business a day.
- Record-related cost = 20,000 x 1,500 = Rs 3,00,00,000 (Rs 3 crore).
- Downtime cost = 3 x 2,00,000 = Rs 6,00,000.
- Total = Rs 3,06,00,000, far above the cost of encryption, backups and patching.
Why protection is continuous
Threats change daily, new systems add new weaknesses, and people make mistakes. Protection is therefore a continuing programme of policies, controls, training, monitoring and review, not a one-time purchase.
Conclusion. Information is a valuable asset, and protecting it keeps its confidentiality, integrity and availability, with accountability and authenticity. Failure costs money, brings legal penalties, damages reputation, stops operations, helps competitors and can harm people. The illustrative breach of 20,000 records costs about Rs 3.06 crore, so protection must be continuous.
