The cyber security of the banks is ranked second in the security of the National Cyberspace Center: Banks should be prepared to face cyber attacks and maintain the continuity of essential services by early detection of threats and fixing vulnerabilities. Protecting citizens' identity, financial information and transactions is one of the most important responsibilities of the banking network, and the disclosure of banking information, in addition to financial damages, may affect people's privacy and public trust in the banking system. The ultimate goal of cyber security rating of banks is not only to get a rating, but to increase the resilience of financial infrastructures, protect digital assets and strengthen public trust in banking services.
