Data Classification

Data Classification — The process of categorizing information according to sensitivity, criticality and required protection.

Why Data Classification matters in finance

Controls are more effective when protection is aligned with the value and risk of the data.

Security is also a market-infrastructure question

In financial services, data classification should be understood in relation to operational continuity, data integrity, payments, market infrastructure and interconnected dependencies. A control can be technically effective while still leaving material resilience risk if critical services cannot continue or recover during disruption.
