Integrating COBIT and COSO Frameworks for Fraud-Resistant Banking Information Systems: A Unified Model for Enhanced Audit Reliability

Abstract

This research develops and validates an integrated framework combining COBIT
(Control Objectives for Information and Related Technologies) for IT governance
and COSO (Committee of Sponsoring Organizations) for internal control to create
fraud-resistant banking information systems. Through systematic analysis of 143
banking institutions across North America and Europe from 2017 to 2019, this study
demonstrates that the integrated COBIT-COSO model significantly enhances audit
reliability and fraud detection capabilities. The proposed framework addresses critical gaps in existing approaches by aligning IT governance objectives with internal
control activities through a unified risk assessment methodology. Empirical results
indicate that banks implementing the integrated framework experienced 54% improvement in fraud detection rates and 63% reduction in false positives compared
to institutions using either framework in isolation. The research introduces a novel
maturity assessment tool that quantifies integration effectiveness and provides actionable guidance for implementation. Findings reveal that successful integration
requires organizational commitment, cross-functional collaboration, and continuous monitoring mechanisms. This study contributes to both academic literature
and practical implementations by providing evidence-based insights for enhancing
banking information system resilience against evolving fraud threats.
