Which ISO/IEC standard addresses issues relevant to financial services?

The correct choice highlights ISO/IEC TR 27015, which specifically addresses the information security management aspects pertinent to financial services organizations. This standard provides guidelines tailored to help financial institutions implement and manage their information security management systems (ISMS) effectively, taking into account the unique challenges and regulatory requirements faced by this sector.

This standard is designed to help these organizations identify risks and apply appropriate controls in line with the broader ISO/IEC 27001 framework. It ensures that the specific contexts and needs of financial services are considered, facilitating better risk management and compliance with laws and regulations that govern the handling of financial data.

In comparison, the other options focus on different areas or broader topics within the information security domain. For instance, ISO/IEC 27011 provides guidance related to telecommunications organizations, while ISO/IEC TR 27016 addresses economics in the context of information security, and ISO/IEC 27006 pertains to requirements for bodies providing audit and certification of ISMS. These documents serve important purposes but do not specifically target the financial services domain as directly as ISO/IEC TR 27015 does.
