Cyber Hygiene in India: Growing Digital Security Risks and Solutions

Context

India’s expanding digital economy has increased dependence on online payments, banking, public platforms and digital identity systems. Rising cyber-fraud reports and costly data breaches have made cyber hygiene essential for protecting institutions, users and trust in the digital economy.

What is Cyber Hygiene?

1. Cyber hygiene refers to routine practices that keep devices, networks, accounts and data secure, similar to preventive hygiene in public health.
2. It includes software updates, strong passwords, multi-factor authentication, secure backups and phishing awareness, reducing avoidable vulnerabilities before attackers exploit them.
3. Preventive value: Basic security practices reduce the likelihood that minor vulnerabilities develop into fraud, data exposure or prolonged operational disruption.

Rising Economic Cost of Cyber Risk

1. Data-breach cost: IBM’s 2026 report placed India’s average organisational breach cost at ₹25.5 crore, up 15.9% year-on-year, showing the growing financial impact of detection, disruption and recovery.
2. Financial-sector exposure: Average breach costs in financial services reached ₹40.9 crore, reflecting the sensitivity and economic value of financial and identity data.
3. Cyber-fraud scale: Amounts reported by citizens through cyber-fraud reporting systems rose from ₹551 crore in 2021 to ₹22,848 crore in 2024, before easing marginally to ₹22,495 crore in 2025. These represent reported amounts, not necessarily final realised losses.

Why Digital Expansion Amplifies Risk

1. Transaction scale: UPI processed about 186 billion transactions in FY2024–25, meaning even low-frequency vulnerabilities can potentially affect a very large user base.
2. Interconnected ecosystem: Banks, payment platforms, cloud services and identity systems increasingly depend on one another; weakness at one node can therefore create wider operational or trust risks.
3. Human vulnerability: IBM identified phishing-related attacks as a major initial attack vector in India, showing that technological safeguards must be complemented by user awareness.

Cyber Incidents and Digital Trust

1. Financial-data risk: SBI investigated suspected exposure of customer information on the dark web; although core banking operations remained unaffected, such identity-data exposure can increase risks of phishing and financial fraud.
2. Digital-trust risk: Weak cryptographic keys affected eight eMudhra intermediate TLS certificate authorities. No customer-data breach was reported, but the incident showed how weaknesses in certificate infrastructure can affect confidence in website authentication.
3. Broader implication: Cybersecurity must therefore protect not only stored data but also the trust mechanisms that authenticate digital transactions and communications.

Building Cyber Resilience

1. Reduce human-layer vulnerability: Strong passwords, multi-factor authentication, timely updates and phishing awareness can block common attack pathways, reducing the probability of account compromise and fraud.
2. Strengthen organisational resilience: Regular patching, encryption, penetration testing and incident-response drills can limit vulnerabilities and shorten disruption when a breach occurs.
3. Improve institutional coordination: CERT-In, under Section 70B of the Information Technology Act, provides national incident-response coordination and reporting requirements, enabling faster threat sharing and containment.
4. Shift from prevention to resilience: Since no digital system can be completely secure, cybersecurity strategy must combine prevention, early detection, rapid containment and recovery, reducing both the frequency and impact of attacks.
