Which of the following describes a group of standards created as a series of best practices across multiple industries?

The concept being described in the question aligns best with the idea of a framework. Frameworks are designed to provide a structured approach to achieving specific goals or standards, often encompassing a collection of best practices that can be applied across various industries. They help organizations implement effective security measures by providing guidelines that can be customized according to their unique environments and requirements.

While the International Organization for Standardization (ISO) does create many internationally recognized standards, it is not accurate to say that it describes a group of standards across multiple industries. Instead, ISO represents a body that develops and publishes these standards. Regulatory compliance refers to the adherence to laws, regulations, guidelines, and specifications relevant to an organization, which is more specific and legalistic in nature. Methodology, while it can be similar to a framework, generally refers to a more defined system or process for completing tasks rather than a broad grouping of best practices.

Thus, understanding frameworks as collections of best practices that can be applied across various industries captures the essence of the question perfectly, differentiating it from ISO, regulatory compliance, and methodology.
