A cloud administrator is moving a healthcare application to the public cloud. The application needs to be secured while data is being stored. Which of the following technologies should be deployed…

Self-encrypting drives provide direct data at rest encryption, which is a primary security measure, but the question implies a broader or more efficient approach that compression might enable for the entire application lifecycle.

Data masking obfuscates sensitive data, primarily for use cases like testing environments, and doesn't directly secure the data in its primary stored state for the application.

Deduplication reduces redundant copies of data to save storage space but does not inherently secure the data or its contents while being stored.

Data compression reduces the overall volume of data stored, which can lead to performance improvements for backup and recovery operations, thus enhancing the availability and resilience aspects of data security. Additionally, by reducing storage costs, it can indirectly free up resources for other direct security measures.
