Final answer:
The CIA Triad principle that necessitates the encryption of passwords in a database is Confidentiality. Encryption helps keep passwords unreadable to anyone without proper access, thus ensuring they remain private and inaccessible to unauthorized individuals.
Step-by-step explanation:
The aspect of the CIA Triad that requires that passwords in a database be encrypted is Confidentiality. The CIA Triad, which stands for Confidentiality, Integrity, and Availability, is a model designed to guide policies for information security within an organization. Confidentiality ensures that sensitive information is accessed only by authorized individuals and remains private or secret. By encrypting passwords, an organization is taking steps to prevent unauthorized access to the information, thus maintaining its confidentiality. This is essential as passwords are often the keys to accessing many forms of data and systems. Encryption transforms the original password into an unreadable form for those without the proper decryption key, making it more difficult for hackers and malicious actors to gain unauthorized access. Therefore, password encryption is a crucial measure for protecting data and upholding the principles of the CIA Triad.
