TOPIC CLASSIFICATION
Subject: Science & Technology / Internal Security Sub-area: Cybersecurity Prelim PYQ Trend: High (regular questions on malware, CERT-In, cyber laws) Mains Relevance: GS-3 (Internal Security, Science & Technology)
EXAMINER REASONING
Cyber threats are a high-yield UPSC topic straddling Science & Tech and Internal Security. The examiner focuses on: (a) types of threats — malware, phishing, ransomware, APTs; (b) India's institutional mechanism — CERT-In, NCIIPC, sectoral CERTs; (c) vulnerabilities — supply chain, IoT, AI-based attacks; (d) legal framework — IT Act 2000, amendments, data protection. Expect questions that ask you to link cyber threats with critical infrastructure (power grid, financial system, defence) and India's preparedness gap.
