Which pillar of data security is associated with usernames and encryption?

The correct answer is associated with confidentiality, which is a fundamental principle of data security focused on ensuring that information is not accessed by unauthorized individuals. Usernames are a critical component of authentication processes, which help ensure that only users with the proper credentials can access sensitive information. Encryption plays a vital role in confidentiality by converting data into a format that can only be read by individuals who possess the appropriate decryption keys. This protects sensitive information from being exposed during data transmission or storage.

Confidentiality is essential in healthcare and other sectors where sensitive data is handled, as it safeguards personal information and upholds privacy standards. By implementing strong username protocols and effective encryption strategies, organizations can limit access to data and protect it from unauthorized disclosure.
