Cyber Security Threats

In an era where governance, commerce, and everyday life are increasingly mediated by digital networks, cyber security threats have emerged as a critical national security challenge. From ransomware attacks on critical infrastructure to disinformation campaigns that sway public opinion, these threats undermine the integrity of state institutions, economic stability, and the privacy of citizens. For UPSC aspirants, understanding the cyber threat landscape is essential not only because it features prominently in the National Security Strategy and Digital India initiatives, but also because the Constitution’s guarantee of the right to privacy (Article 21) and the State’s duty to protect life and liberty now extend into the virtual realm.

Constitutional / Legal Foundation

The Supreme Court’s recognition of privacy as a fundamental right (Justice K.S. Puttaswamy v. Union of India, 2017) and the enactment of the Information Technology Act, 2000 (amended 2008) together provide the legal bedrock for combating cyber offences and safeguarding digital rights.

Exam relevance

UPSC Stage	Relevance
Prelims	Frequently asked as static GK (e.g., “Which agency handles cyber‑security in India?”) and current affairs (major ransomware attacks, policy updates).
Mains	Appears in GS‑II (technology & security), GS‑III (governance & policy), and Essay topics (e.g., “Balancing privacy and security in the digital age”). Questions may demand analysis of policy effectiveness, legal adequacy, or the geopolitical implications of state‑sponsored cyber‑operations.

A solid grasp of cyber security threats equips you to answer both factual and analytical questions, linking technology with national security, law, and governance—core themes of the UPSC syllabus.
