Digital Pathogen: Why Cyber Hygiene Is No Longer Optional
Context: Rising data breaches and cyber frauds in India's fast-growing digital economy show that basic cyber hygiene is now the first line of defence for banks, businesses, regulators and citizens alike.
What Is Cyber Hygiene?
Routine practices that keep devices, networks and data secure — the digital equivalent of personal hygiene.
Term coined by internet pioneer Vinton Cerf in 2000, in testimony before the U.S. Congress.
Like public health, prevention is cheaper than cure.
Key Data
Average ₹25.5 crore per breach in India (IBM 2026), up 15.9%; financial sector ₹40.9 crore.
RBI (2023-24): 36,075 cases involving ₹13,930 crore; 29,082 linked to cards/internet banking.
From ₹551 crore (2021) to ₹22,848 crore (2024); ₹22,495 crore in 2025 (MHA).
UPI processed about 186 billion transactions in 2024-25 (NPCI).
Why the Risk Is Rising
UPI, mobile banking and digital lending are linked — a weak point in one can spread across the chain.
Vendors and payment intermediaries can become entry points; even CBFC and eMudhra faced issues.
Breaches cause identity theft, fraud, business disruption and loss of public trust.
Way Forward
Strong unique passwords, password managers, multi-factor authentication, updates, no suspicious links.
Timely patching, encryption, phishing simulations, penetration testing and incident-response drills.
Security across the whole technology supply chain; coordinated reporting with CERT-In and regulators.
Previous-Year Question
Discuss the potential threats of cyber attack and the security framework to prevent it.
