Which encryption method should be prioritized for protecting sensitive data stored on cloud resources?

1. Application-level encryption

2. Database-level encryption

3. File-level encryption

4. Transport-level encryption

The correct answer is: Database-level encryption

Database-level encryption is a crucial method for safeguarding sensitive data stored in cloud resources because it directly secures data at rest within the database environment. This approach ensures that all the sensitive information stored in a database is encrypted, thereby protecting it from unauthorized access or breaches. By applying encryption at the database level, sensitive data remains secure even if the database is accessed by individuals with access privileges, ensuring that only those who possess the decryption keys can read the sensitive information. Additionally, database-level encryption often integrates seamlessly with cloud service providers' security frameworks, making it easier to manage and monitor encryption practices. This method also helps organizations meet compliance requirements, as it demonstrates a commitment to protecting sensitive information in a robust manner. While other types of encryption, like application-level or file-level, provide security benefits, database-level encryption specifically addresses vulnerabilities associated with stored data, making it a priority for cloud resource protection.
