Least Privilege

Least Privilege — The principle of granting only the minimum access required for a task.

Why Least Privilege matters in finance

It reduces the damage that a compromised identity or application can cause.

Security is also a market-infrastructure question

In financial services, least privilege 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.
