Which regulation requires a CSP to comply with copyright law for hosted content?

The Digital Millennium Copyright Act (DMCA) is the regulation that requires cloud service providers (CSPs) and other online platforms to comply with copyright law for hosted content. The DMCA was enacted to update copyright laws in response to advancements in technology and the rise of the Internet. One of its key components is the safe harbor provision, which allows CSPs to avoid liability for copyright infringement committed by users of their services as long as they follow certain procedures, such as promptly responding to takedown notices from copyright holders. This ensures that CSPs take appropriate actions regarding the copyrighted material uploaded by their users while balancing the rights of content creators.

The other options do not pertain specifically to copyright compliance. The Stored Communications Act (SCA) addresses privacy and access to electronic communications but does not involve copyright issues. The Sarbanes-Oxley Act (SOX) primarily focuses on financial practices and corporate governance, and the Gramm-Leach-Bliley Act (GLBA) deals with the protection of consumer financial information. Therefore, the DMCA is the relevant regulation regarding copyright law for hosted content by CSPs.
