The Indian government has declared the Arunika supercomputer a 'protected system' under the IT Act, 2000, to enhance cybersecurity for critical scientific infrastructure. Inaugurated in September 2024, Arunika is vital for medium-range weather forecasting and disaster early-warning services.

The designation provides legal protection against unauthorized access, with access limited to authorized personnel under strict role-based guidelines. This initiative aligns with the government's efforts to secure digital infrastructure against cyber threats, especially concerning sensitive meteorological data and climate analytics.
