Technical Note on Cross-Sectoral Cyber Mapping Exercise
The Hong Kong Monetary Authority, Securities and Futures Commission, Insurance Authority, and Mandatory Provident Fund Schemes Authority developed an inaugural Cyber Map to understand cyber risk concentration and interdependencies within Hong Kong's financial system. This involved collecting data from approximately 50 selected financial institutions across banking, retail payment, securities, capital markets, mandatory provident fund, and insurance sectors in late 2025. The methodology utilized a three-layered structure to map financial services, critical operations, supporting applications, and underlying IT infrastructure components, capturing around 2,900 dependencies for targeted supervision and incident response.
