Reserve Bank of India (Small Finance Banks - Cybersecurity, Technology: Risk, Resilience and Assurance Framework) Directions, 2026
Summary
Check the official recordThe Reserve Bank of India mandates a comprehensive framework for Small Finance Banks to manage information technology and cybersecurity risks. Banks must establish an IT Governance Framework, a Board-level IT Strategy Committee, and an Information Security Committee. The directions require banks to implement robust cybersecurity controls, including data leak prevention, secure configuration, network security, and continuous surveillance through a Cyber Security Operations Centre. Banks must conduct periodic vulnerability assessments and penetration testing on critical systems. The framework also covers business continuity, disaster recovery, and incident response management. Banks must report cyber incidents to the RBI within six hours of detection. These directions apply to all Small Finance Banks and take effect immediately.
