A company stores large volumes of data that are infrequently accessed but must remain secure. What feature should be implemented on their file system to optimize storage space while maintaining confidentiality?
Encryption protects the confidentiality of data by ensuring that if it falls into the wrong hands, it cannot be read without the appropriate decryption key. Compression reduces the size of files, optimizing storage space; however, it alone does not protect the content's confidentiality. Combining both encryption and compression addresses both requirements of optimizing storage space and maintaining the confidentiality of the data.
