How does confidentiality relate to encrypted information?

• A. It promotes data integrity for stored files
• B. It allows anyone to access all information freely
• C. It ensures only personnel with decryption keys can access it
• D. It focuses on the compression of data files

Answer: (C)

Confidentiality in the context of encrypted information is primarily concerned with ensuring that sensitive data remains private and is accessible only to authorized individuals. When information is encrypted, it is transformed into a format that is unreadable to anyone who does not possess the correct decryption key. This encryption process protects the data from unauthorized access, thereby maintaining its confidentiality.

By requiring specific decryption keys for access, organizations can control who can view the information, which helps protect against data breaches and unauthorized disclosures. This is essential for safeguarding sensitive information such as personal data, financial records, or proprietary business information. Therefore, the option that links confidentiality to ensuring that only those with the proper decryption keys can access the information accurately reflects the role of encryption in maintaining data confidentiality.
