Transference is a risk response strategy that involves shifting the responsibility or impact of a risk to a third party, such as an insurance company, a vendor, or a partner. By purchasing insurance, the company transferred the financial liability of the cloud migration project to the insurance provider, in case of any losses or damages. Transference does not eliminate the risk, but it reduces the exposure of the company to the risk.

Application scanning is an automated tool used to detect vulnerabilities or defects in the code of a software application. This tool can help identify security issues such as coding errors, weak configurations, or other vulnerabilities that could potentially be exploited. In this case, the company is using an automated tool to improve platform security by identifying and fixing code defects, which aligns with application scanning.

Data encryption is the best option for enforcing confidentiality in the event of a breach. By encrypting proprietary data, even if unauthorized access occurs, the data remains unreadable without the decryption key, ensuring that confidentiality is maintained. This is a key measure for protecting sensitive information hosted in the public cloud.
