Cyber Security — Definition
Definition
Cyber security refers to the practice of protecting digital systems, networks, and data from cyber attacks, unauthorized access, and digital threats. In the Indian context, cyber security has evolved from a technical IT concern to a critical national security imperative.
With India's rapid digital transformation through initiatives like Digital India, the country has become increasingly dependent on digital infrastructure for governance, commerce, and daily life. This digital dependence has created new vulnerabilities that adversaries can exploit.
Cyber security encompasses multiple dimensions: protecting critical information infrastructure like power grids, banking systems, and telecommunications networks; safeguarding citizen data and privacy; ensuring business continuity in the digital economy; and defending against state-sponsored cyber attacks.
The scope includes technical measures like firewalls and encryption, institutional frameworks like CERT-In and NCIIPC, legal provisions under the IT Act 2000, and policy initiatives like the National Cyber Security Strategy 2020.
For UPSC aspirants, understanding cyber security requires grasping both its technical aspects and its integration with broader governance and security frameworks. The topic frequently appears in questions related to internal security, governance, and current affairs.
Key institutions include the National Security Council Secretariat which houses the National Cyber Security Coordinator, the Computer Emergency Response Team-India (CERT-In) under the Ministry of Electronics and IT, and the National Critical Information Infrastructure Protection Centre (NCIIPC) under the National Technical Research Organisation.
Recent developments like the Personal Data Protection Bill, increasing cyber attacks on government and private systems, and India's growing role in global cyber governance make this a highly relevant topic for both Prelims and Mains examinations.
