Cybersecurity

noun (uncountable)

/ˈsaɪbəsɪˌkjʊərɪti/

The practice of protecting internet-connected systems, networks, software, and data from digital attacks, unauthorised access, damage, or disruption. In UPSC/GS3 context, key institutions include CERT-In (Indian Computer Emergency Response Team, under MeitY), the National Cyber Security Policy 2013 (under revision), and the National Critical Information Infrastructure Protection Centre (NCIIPC) protecting critical sectors such as power, banking, and telecom. India's Digital Personal Data Protection Act 2023 (DPDP Act) strengthens data security obligations for data fiduciaries, while CERT-In's April 2022 directions mandating 6-hour breach reporting represented a major regulatory escalation.

✍️ Usage in a UPSC answer

CERT-In's April 2022 directive — requiring all service providers, intermediaries, and data centres to report cybersecurity incidents within six hours of detection — reflects a decisive shift from reactive incident management to mandatory proactive disclosure in India's evolving cyber-governance architecture.

🌱 Word Family

cybersecurity (n), cyber (prefix/adj), cyberattack (n), cybercrime (n), cyber resilience (n), cyberspace (n), cyber threat (n phrase)

🔡 Root

Greek kybernan = to steer, govern (source of cyber-, via Norbert Wiener's cybernetics, 1948); Latin securus = free from care (se- = without + cura = care)

📜 Etymology

The prefix cyber- derives from Norbert Wiener's cybernetics (1948), itself from Greek kubernetes ('steersman'). Security derives from Latin securitas (from securus, 'free from care'). The compound cybersecurity crystallised in the 1990s with the rise of commercial internet infrastructure; it became a formal policy term in US National Security Directives of the early 2000s.

🧠 Memory Hook

CYBER (steersman in Greek) + SECURITY (safe from care in Latin): cybersecurity steers your data safely through the digital ocean. Wiener coined 'cybernetics' from kubernetes (steersman) — a helmsman who keeps the ship — and your data — on course.
