IS Audit RBI Guidelines
Securexocean delivers IS Audit services for NBFCs and RBI-regulated entities in full conformance with Terms of Reference prescribed by RBI and ICAI — covering IT governance, information security, business continuity, and IT outsourcing controls.
Service Introduction
RBI's Master Directions on IT Framework for the NBFC Sector mandate that all registered NBFCs conduct periodic Information Systems audits evaluating the adequacy of IT governance, information security controls, network and application security, business continuity planning, and IT outsourcing risk management — conducted by a qualified external auditor.
Audit scope differs based on asset size. Systemically important NBFCs with assets of Rs.500 crore or more face requirements covering IT governance frameworks, IS audit procedures, IT operations management, BCP and DR, and IT outsourcing controls. NBFCs below this threshold are subject to scaled requirements. Securexocean conducts RBI IS Audits following RBI and ICAI Terms of Reference, producing audit reports formatted for regulatory submission.
Threat Landscape
RBI's information security requirements demand that access to sensitive customer and transactional data be restricted through documented access control policies and audit trails. Data integrity controls ensure financial records cannot be altered without detection. Business continuity plans must demonstrate critical system restoration within defined recovery time objectives. Authentication controls governing digital transactions must confirm that transactions can be attributed to verified users and cannot be repudiated.
Organizations that approach IS audit compliance without adequate preparation consistently face findings in access governance, BCP documentation, and log management that create regulatory exposure at the point of submission.
Control Gaps That Consistently Appear in Pre-Audit Assessments
Absence of a board approved Information Security Policy covering all RBI mandated domains
Insufficient network segmentation and perimeter security around core banking infrastructure
Undocumented or untested BCP and DR plans not meeting RBI recovery objective requirements
IT outsourcing arrangements without formal vendor contracts covering security and audit rights
Inadequate log management with insufficient retention periods and absent centralized monitoring
Absence of a defined IS Audit cycle and prior audit evidence creating governance deficiencies
