Which of the following is a countermeasure method implemented to address regulatory violations in cloud security?

Implementing Digital Rights Management (DRM) solutions is a robust countermeasure to address regulatory violations in cloud security. DRM technologies help organizations control and protect digital content and sensitive data from unauthorized access and misuse. By managing the rights to use, distribute, and modify information, DRM can ensure compliance with various regulations such as GDPR, HIPAA, or other data protection laws.

This control over data is particularly significant in cloud environments, where data is often shared and stored across multiple locations and platforms. By enforcing policies around who can access particular data, under what circumstances, and ensuring that only authorized users can perform specific actions, organizations can significantly mitigate risks associated with regulatory violations.

The other options do not directly address regulatory compliance in the same way. For instance, hiring additional technical support primarily boosts operational capacity without specifically targeting regulatory needs, while limiting cloud access may enhance security but does not inherently ensure compliance with regulations. Establishing new cloud architectures might improve the overall security posture but may not directly correlate with addressing regulatory mandates unless those architectures specifically incorporate compliance measures.
