Critical Infrastructure at Risk: Cybersecurity Shifts to Life Safety

Cyber Attacks on Critical Infrastructure Pose Direct Threat to Human Lives: Expert​

Cyber Threat Landscape Expands Beyond Data Theft​

New Delhi, March 28 – As cyber attacks increasingly target critical infrastructure such as healthcare systems and power grids, the global threat landscape is evolving from data breaches to direct risks to human lives, according to a senior cybersecurity expert.

Gaurav Shukla, Partner and Leader – Cyber at Deloitte South Asia, highlighted that cyber risks are no longer confined to information systems but now impact real-world safety and operations.

IT-OT Convergence Increases Vulnerability​

Shukla noted that the convergence of Information Technology (IT) and Operational Technology (OT) has significantly expanded the attack surface. This shift has made sectors such as aviation, transportation, and public utilities increasingly vulnerable to cyber threats.

He emphasized that rapid digital transformation in recent years has created more entry points for attackers, increasing the likelihood of disruptions across critical systems.

From Data Security to Human Safety​

Highlighting the severity of modern cyber risks, Shukla explained that attacks can now directly endanger human lives. For instance, a cyber breach in connected vehicles could result in loss of control while driving, posing immediate physical danger.

Similarly, cyber attacks on medical devices that manipulate patient data or interfere with functionality could have fatal consequences.

Power Grids and National Infrastructure at Risk​

Shukla warned that attacks on power generation and transmission infrastructure could lead to widespread blackouts, severely impacting national security and economic stability.

He stressed that safeguarding critical infrastructure is now essential to preventing large-scale disruptions.

Surge in IoT Devices Expands Attack Surface​

The rapid growth of Internet of Things (IoT) devices has further complicated the cybersecurity landscape. With over 30 billion IoT sensors globally, the average individual is surrounded by more than 3.5 connected devices at any given time.

This surge in connectivity significantly increases exposure to cyber risks.

India Stack Emerges as Global Digital Benchmark​

Speaking on India’s digital progress, Shukla highlighted the success of India Stack, also known as Digital Public Infrastructure (DPI), which has become a global benchmark.

He noted that Deloitte is currently advising around 24 countries to develop their own versions of India Stack, reflecting its growing global influence.

Rising Risks with Expanding Digital Public Infrastructure​

However, Shukla cautioned that as DPI expands beyond identity and payments into sectors like education and healthcare, new vulnerabilities emerge at integration points.

With DPI accounting for nearly 80% of India’s digital payments in January, ensuring its cybersecurity resilience is critical for national security.

AI-Driven Cyber Attacks Increase Threat Velocity​

Shukla also warned that the use of Artificial Intelligence by cyber attackers is accelerating the scale and speed of threats. He stressed the need for continuous testing, especially against supply chain vulnerabilities and AI-driven attack vectors.

Cyber Warfare Requires Continuous Vigilance​

Drawing a comparison with traditional warfare, Shukla pointed out that cyber warfare is continuous and not time-bound. This requires ongoing collaboration between enterprises, academia, and government bodies to build robust defense mechanisms.

Need for Cybersecurity Education from Early Stages​

He advocated for integrating cybersecurity awareness and digital ethics into primary education. Emphasizing its importance, he noted that understanding privacy and digital safety is becoming as fundamental as learning a language in today’s digital age.
