- Import dependence: Heavy reliance on imported hardware and software create supply chain vulnerabilities and security risks.
- Large digital footprint with low digital literacy: Only 38% of households in India are digitally literate. (CBWE)
- Limited redundancy: Lack of adequate backup and redundancy measures, making systems more vulnerable to single points of failure.
- Others: State-sponsored cyber-attacks, lack of robust cybersecurity protocols, etc.
