A security breach has occurred involving the company e-commerce server. Which parties should be informed about the release of customer credit card data?

The release of customer credit card data is a serious breach of security that must be addressed promptly and transparently. Informing affected customers is critical as they have a direct stake in the security of their financial information and need to take steps to protect themselves from potential fraud. Credit card companies also need to be notified so they can monitor for fraudulent activity and take necessary actions such as issuing new cards or enhanced fraud protection services. Law enforcement agencies should be involved as they can investigate the breach and help mitigate any further risks associated with the compromised data.

This course of action not only helps to protect the customers but also fulfills legal obligations that may be required under data protection laws and regulations, which often mandate that companies inform affected individuals and relevant authorities in the event of a data breach.
