Which of the following is NOT a main component of the CIPP/US body of knowledge?

The reasoning behind identifying "insurance regulations" as not being a main component of the CIPP/US body of knowledge centers on the focus of the certification. The CIPP/US framework primarily emphasizes U.S. federal and state privacy laws, compliance practices, and sector-specific regulations related to data protection and privacy rights.

The CIPP/US certification is designed to cover laws and regulations that govern privacy and data handling in a variety of contexts, but it does not specifically address insurance regulations, which are more narrowly focused and typically governed by their own regulatory frameworks separate from general privacy concerns. The primary components of the body of knowledge encompass a broader scope involving privacy law and compliance, making it essential for professionals working across various sectors where data privacy is pertinent. Hence, insurance regulations do not fit into the main topics covered in the CIPP/US curriculum.
