Can you have confidentiality without integrity

Confidentiality means that data, objects and resources are protected from unauthorized viewing and other access. Integrity means that data is protected from unauthorized changes to ensure that it is reliable and correct. Message Digest is used to ensure the integrity of a message transmitted over an insecure channel where the content of the message can be changed. The message is passed through a Cryptographic hash function. Explanation: The term data tampering is used when integrity is compromised in any security model and checking its integrity later becomes costlier.

What is the term that best describes the following: a sender is not able to deny sending a message, e. A message has integrity if: A. There are two main types of data at risk. The first is sensitive information, such as credit card information, passwords or contact lists.

Since the library is open to public, everyone can access this database, so there is no confidentiality at all, but since the users accessing the database are not allowed to change the information stored in the database integrity of the system is not compromised.

Note from TA: Each part 1 point — Total 2 points. For this question the answer depends on your definition of integrity and confidentiality. Other solutions are also accepted if enough reasoning is given. Anna does not have read permission as. Anna does not have write permission as.
