Which statement contrasts secret information with available information?

• A. Secret information is accessible to everyone
• B. Secret information is not accessible by authorized people
• C. Secret information requires privacy; Available information is accessible to authorized people
• D. Secret information cannot be stored

Answer: (C)

Access control and privacy define the distinction between secret information and information that’s available. Secret information is kept private so that only people with authorization can access it, often protected by policies, encryption, and secure handling. Available information, while still subject to permission, is intended to be accessible to those who have the right to view it, reflecting a controlled but broader access model. The statement that secret information requires privacy and that available information is accessible to authorized people cleanly captures this contrast: secrecy depends on keeping data private, while usefulness of data depends on being accessible to those who need it. The other options misstate the idea: secret information isn’t meant to be accessible by everyone, and secret information isn’t inherently unable to be stored.
