Confidentiality means that information is only accessible to authorized persons. Unauthorized third parties, on the other hand, have no access to transmitted messages or stored information.

Confidentiality is one of the three goals defined for security. The other two are integrity and availability. As far as confidentiality is concerned, for example, only a restricted, authenticated group of people can read a message. When two communication partners communicate, only the sender and the recipient of the message can read it in plain text. To ensure confidentiality, the data stored in the system or transmitted in the communication equipment must be protected from unauthorized access by encryption. Confidentiality can be associated with discretion or secrecy.

Confidentiality is essential for data processing and data communication to be as secure and effective as possible.
