- Two-factor authentication
- Username ID and password
Answers Explanation & Hints: The three methods that can be used to ensure confidentiality of information are:
- Data encryption
- Two-factor authentication
- Username ID and password
Data encryption involves encoding information in a way that makes it unreadable to anyone who does not have the decryption key. This helps ensure that sensitive information remains confidential, even if it falls into the wrong hands.
Two-factor authentication adds an additional layer of security to login procedures, requiring users to provide a second factor (such as a code sent to their mobile phone) in addition to their username and password. This helps prevent unauthorized access to sensitive information, even if an attacker manages to obtain a user’s login credentials.
Username ID and password is a correct method to ensure confidentiality of information. By requiring a username and password to access sensitive information or systems, it limits access to only those who have been granted permission and provides a layer of authentication to verify the identity of the user. This helps to prevent unauthorized access and protect the confidentiality of the information.
