What is an example of a document that would include customer account information?

The correct answer is GLBA, which stands for the Gramm-Leach-Bliley Act. This act is a United States federal law that requires financial institutions to explain their information-sharing practices to their customers and to safeguard sensitive customer data. It mandates that organizations must protect customer account information, which includes personal financial data and account details. Therefore, any document that falls under the GLBA would serve to address how customer account information is collected, managed, and protected, making it a key component in compliance and data privacy practices.

In contrast, while the other options mentioned relate to security frameworks and guidelines, they do not focus specifically on customer account information in the same way. For instance, the SOC 2 Report is primarily concerned with service organization controls and the trust services criteria (security, availability, processing integrity, confidentiality, and privacy) governing service providers, rather than detailing individual customer data. NIST SP 800-122 discusses the management of personal information in organizations' IT systems and provides guidance on protecting personally identifiable information (PII), but it's not a regulatory document describing specific account information. ISO/IEC 27050-1:2016 focuses on the management of electronic evidence and is not directly related to customer account information handling.
