Information Security Overview

Within the field of information security there is a concept known as the CIA Triad which stands for Confidentiality, Integrity and Availability. Confidentiality ensures that information is only viewed by those who are supposed to have access to it. Integrity ensures that the information that is transferred is intact and remains unmodified. Availability ensures that data is readily available to those who are authorized to access it. Different elements of the CIA Triad will be of more interest to different groups depending on what threat actor is being discussed.
2. For example a nation state actor is generally interested in cyber espionage so they may focus their efforts on gaining access to confidential information. They may also be interested in modifying data in motion in order to spread disinformation through the ranks of their adversary. A cyber criminal group may be more interested in denying availability through crypto malware in order to demand a ransom to unlock the service. And a hacktivist may be less interested in the modifying information or affecting availability and more focused on disclosing confidential information about their target.
