Introduction: The Capstone Challenge
In Lessons 1.1 through 1.7, we established the complete theoretical and practical framework for cybersecurity in financial institutions. We explored the threat landscape, the regulatory framework, cyber threat intelligence, risk assessment, security frameworks and controls, cyber governance, and cybersecurity metrics.
This final lesson of Module 1 is theΒ Capstone Projectβan exercise in building a comprehensive cybersecurity program for a financial institution. This project integrates all seven lessons into a single, unified cybersecurity program.
The capstone project is designed to be a portfolio piece that demonstrates your mastery of cybersecurity principles for financial institutions. By the end, you will have a complete, production-ready cybersecurity program that is mathematically rigorous, practical, and applicable to real-world financial institutions.
