Blog: NASSCOM Official Blog

The moment since Operational Technology (OT) and Information Technology (IT) have fused, new doors to possibilities have opened. This convergence has added new capabilities to industrial control systems (ICS) and brought several benefits including enhanced productivity, improved system performance, and reduced costs. Along with numerous advantages, it has also generated a new set of vulnerabilities and expanded the attack surface of the critical infrastructures like power generation plants, water treatment plants, oil & gas refining plants, transport systems, etc. As per a recent report1, 74% of IT security professionals globally are more concerned about a cyber-attack on critical infrastructure compared to an enterprise data breach.

Growing Attacks on Critical Infrastructures

The world has witnessed a lot of devastating cyber-attacks on industrial control systems right from the year 1903 when hackers compromised the Marconi’s secure wireless telegraph presentation with Morse code. One of the famous cyber-attacks that holds a special place in the books of history took place in 2010 at Iran’s Natanz uranium enrichment facility, where the Stuxnet worm reportedly destroyed numerous centrifuges.

The primary factor behind this rising frequency is the growing reliance on Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs) and distributed control systems for controlling physical devices and monitoring processes.

Now, let’s glance through some recent cyber-attacks on critical infrastructures in India and across the globe:

Challenges to the Security of Critical Infrastructures

Apart from the above-mentioned major challenges, there are some other factors as well that impact the security of critical infrastructures.
