Abstract :
Cyber threats are gaining traction and spreading like wildfire among financial institutions, and demand proactive
assessment measures that integrate technical (network) vulnerabilities with business impact metrics. This study developed a
comprehensive cyber-risk scoring and visualization framework capable of addressing the shortcomings of traditional risk
assessment approaches. The framework adopted a multi-layered architecture, where business Key Performance Indicators
(KPIs), such as transaction anomalies and operational costs, and network security metrics (intrusion detection alerts and
vulnerability scans) are merged. Gradient boosting, a machine learning model, was used to classify risks, while autoencoders
were employed to detect anomalies. These tools were trained on the CICIDS2017 dataset for improved predictive capabilities.
Using a dynamic risk-scoring algorithm, the study contextualized cyber threats in terms of financial implications, expressed as
Security Control Scores and Loss Exceedance Curves. The result showed an ROC-AUC risk prediction score of 0.89 when tested
in a simulated medium-sized bank environment with 500 assets. The interactive visualization platform converted risk data into
valuable insights for executives and other stakeholders. In sum, the framework bridges the gap between security measures and
business decision-making in financial institutions to optimize cybersecurity investments, enhance organizational resilience
against cyberthreats, and ensure effective compliance reporting.
