Financial systems increasingly rely on cloud-native infrastructures, exposing them to sophisticated cyberattacks that exploit API vulnerabilities, high-volume transaction flows, and distributed network dependencies. Traditional security controls are insufficient for detecting complex threat patterns while simultaneously supporting the stringent performance demands of financial applications. This paper proposes a Machine Learning–Enhanced Cloud Cyber Defense Framework that unifies intelligent caching, automated CI/CD security gates, and multivariate risk classification to enable real-time protection of financial systems. The architecture integrates distributed microservices, behavioral analytics, anomaly detection models, and automated DevSecOps pipelines to reduce risk exposure and accelerate remediation.
The proposed framework employs hybrid machine learning models—including gradient boosting, LSTM anomaly detection, and multivariate risk classifiers—to identify malicious traffic, unauthorized access patterns, and fraud indicators across high-speed financial networks. Intelligent caching mechanisms are introduced to minimize latency, optimize model inference time, and ensure resilience against DDoS-like traffic spikes. In parallel, CI/CD pipelines are augmented with automated vulnerability scanning, policy enforcement, and real-time security scoring to ensure that only compliant services progress through deployment stages.
Experiments using large-scale financial logs, synthetic attack datasets, and credit risk corpora demonstrate that the framework improves threat detection accuracy by up to 94%, reduces API response latency by 38% through cache optimization, and enhances CI/CD security efficiency by 41%. Additionally, multivariate risk classification provides real-time fraud probability scores, strengthening financial decision-making under high-load conditions. Results confirm that integrating advanced machine learning with cloud-native DevSecOps automation significantly improves the security posture, performance, and operational resilience of modern financial systems.
