Overview
🎯
Why it matters
Every data breach, every ransomware attack, every password leak — security failures cost billions. Understanding encryption, authentication, and security protocols is critical in our connected world.
💼
Placement relevance
Cybersecurity Engineer roles growing rapidly. Banks, fintech, defense sectors hire security specialists. Certifications (CEH, CISSP) add ₹8-15 LPA to salary. High demand, low supply.

Previous Year Questions
Unit 12023 · End Semester10 marks
Given p=11, q=13, e=7 for RSA. Encrypt message M=5. Show key generation (n, φ, d) and encryption step-by-step.
Unit 32022 · End Semester8 marks
Explain Kerberos authentication protocol with a diagram. What are the roles of AS, TGS, and tickets?
Unit 42022 · Mid Semester6 marks
What is SQL Injection? Give an example query and explain how to prevent it using prepared statements.
Exam Strategy
🔐
Crypto math is asked
RSA encryption/decryption with small numbers. Know modular arithmetic (a^b mod n). Euclid's algorithm for finding d. Show all steps.
🛡️
CIA Triad in every answer
Relate every security concept to Confidentiality, Integrity, or Availability. Firewalls maintain Integrity. Encryption ensures Confidentiality.
⚠️
Know attack types
SQL Injection, XSS, CSRF, Phishing — explain with examples and countermeasures. OWASP Top 10 is exam gold.
