Definition - What does Confidentiality mean?
Techopedia explains Confidentiality
Sensitive information or data should be disclosed to authorized users only. In IA, confidentiality is enforced in a classification system. For example, a U.S. government or military worker must obtain a certain clearance level, depending on a position's data requirements, such as, classified, secret or top secret. Those with secret clearances cannot access top secret information.
Best practices used to ensure confidentiality are as follows:
- An authentication process, which ensures that authorized users are assigned confidential user identification and passwords. Another type of authentication is biometrics.
- Role-based security methods may be employed to ensure user or viewer authorization. For example, data access levels may be assigned to specified department staff.
- Access controls ensure that user actions remain within their roles. For example, if a user is authorized to read but not write data, defined system controls may be integrated.
