Final answer:
The part of the CIA Triad that was broken in this situation is confidentiality.option a.
Step-by-step explanation:
The part of the CIA Triad that was broken in this situation is confidentiality.
Confidentiality in the context of information security refers to keeping data protected and only accessible to authorized individuals. In this case, Saar's little brother gaining access to his phone and apps means that the information on the phone was not kept confidential.
Both integrity and availability were not necessarily broken in this situation. Integrity refers to the accuracy and consistency of data, and availability refers to ensuring that data is easily accessible to authorized users when needed. While the little brother may have accessed the phone's apps, there is no mention of him altering or modifying the data, and it does not affect the availability of the phone or its apps to Saar.
The part of the CIA triad that was broken when Saar's little brother figured out the password to his phone is A. Confidentiality. The CIA triad stands for Confidentiality, Integrity, and Availability. These are the three key principles that guide information security measures within an organization or, in this case, for personal device security. Confidentiality is breached when information that is supposed to be kept secret is accessed by someone who is not authorized to view it. Since Saar's intention was to keep his phone's content out of reach from his brother, his little brother gaining access to the apps is a clear breach of confidentiality.
