This has caused financial institutions to rely more on cloud-based infrastructures to carry out their mission-critical activities due to the fast digitalization of financial institutions. Oracle Cloud Infrastructure (OCI) has become one of the platforms that have worked in favor of the financial systems as as far as enhanced security and performance features are concerned. Nevertheless, the increasing complexity of cyber threats will dictate an integrated framework of cyber-resilience that will guarantee continuity, integrity, and availability of financial services. The current paper researches the cyber-resilience of Oracle financial systems based on cloud and offers a secure architecture model to build operational resilience. The research incorporates concepts of cybersecurity, risk management, fault tolerance, as well as business continuity to come up with an all-inclusive resilience architecture. A multi-level security model involves managing the identities, encryption, redundancy, two-fourths watch and automated recovery is examined. Moreover, this study measures currently used resilience mechanisms in OCI and contrasts them to the industry standards and regulatory provisions. To prove the proposed framework, a mixed-method approach of qualitative analysis and quantitative simulation is used. Empirical findings confirm that there are enhanced system availability, decreased recovery time purposes (RTO), and a high level of protection against cyber incidents. The results can help to build confidence in the cloud-based financial systems and give useful advice to the system architectures and policymakers. The paper provides a roadmap to resilient finance-based systems, which can sustain cyber disruption and regulatory compliance and efficiency.
