A central bank is a public institution responsible for monetary policy, financial stability, and the core payment infrastructure that moves money between banks and markets. Because it holds sensitive economic data and often operates or supervises critical systems, it is a high-value target in cyber security.
In real attacks, central banks may face phishing, credential theft, ransomware, data exfiltration, and attempts to disrupt payment services or manipulate trusted information. Defenders protect them with strict access controls, network segmentation, logging, encryption, and strong change management. They also use continuous monitoring and recovery planning so that payment and supervisory functions can keep working under pressure. In practice, cyber resilience at a central bank is about preserving trust as much as protecting systems.
