Exam CIPP-US topic 1 question 125 discussion

SCENARIO -
Please use the following to answer the next question:
Otto is preparing a report to his Board of Directors at Filtration Station, where he is responsible for the privacy program. Filtration Station is a U.S. company that sells filters and tubing products to pharmaceutical companies for research use. The company is based in Seattle, Washington, with offices throughout the U.S. and Asia. It sells to business customers across both the U.S. and the Asia-Pacific region. Filtration Station participates in the Cross-Border Privacy Rules system of the APEC Privacy Framework.
Unfortunately, Filtration Station suffered a data breach in the previous quarter. An unknown third party was able to gain access to Filtration Station’s network and was able to steal data relating to employees in the company’s Human Resources database, which is hosted by a third-party cloud provider based in the U.S. The HR data is encrypted. Filtration Station also uses the third-party cloud provider to host its business marketing contact database. The marketing database was not affected by the data breach. It appears that the data breach was caused when a system administrator at the cloud provider stored the encryption keys with the data itself.
The Board has asked Otto to provide information about the data breach and how updates on new developments in privacy laws and regulations apply to Filtration Station. They are particularly concerned about staying up to date on the various U.S. state laws and regulations that have been in the news, especially the California Consumer Privacy Act (CCPA) and breach notification requirements.
What can Otto do to most effectively minimize the privacy risks involved in using a cloud provider for the HR data?
