Respuesta :

The  cases that it affects which of the Information security requirements is explained below.

What are the Information security violations of the above cases?

Someone has copied your credit card and CVV number has violated the confidentiality as this is to be known only by the owner for if the cvv is known by another person who is not the owner, it may lead to theft of the owners' funds/money.

If someone sends a message “Please come at 10 AM”, the receiver receives “Please come at 10.” and the person did miss the appointment due to the misinformation, it violates the availability. If one is not understanding a message, it is better to clarify so as to know if one will be available,

If the attacker has deleted the installed copy of the Microsoft Office application from your laptop is integrity/confidentiality. One who has integrity will not attack another's' system.
