The primary goal of cyber security is to PROTECT data. To safeguard data from cyber-attacks, the security sector offers a triangle of three connected principles. The CIA trio is the name for this principle. The CIA model is intended to help organizations develop POLICIES for their information security architecture. One or more of these principles has been broken when a security breach is discovered. Confidentiality, Integrity, and Availability are the three components of the CIA model. It's a security paradigm that guides individuals through many aspects of IT security. Let's take a closer look at each section.

Confidentiality: Confidentiality is the same as privacy in that it prevents unauthorized access to data. It entails ensuring that the data is only accessible to those who are AUTHORIZED to use it, as well as restricting access to others. It keeps vital information from getting into the WRONG hands. Data encryption is a great example of keeping information private.
Integrity: This principle assures that the data is genuine, correct, and safe from unwanted threat actors or unintentional user alteration. If any changes are made, precautions should be taken to protect sensitive data from corruption or loss, as well as to quickly recover from such an incident. Furthermore, it DENOTES that the source of information must be genuine.
Availability: This principle ensures that information is constantly available and helpful to those who have access to it. It ensures that system failures or cyber-attacks do not obstruct these accesses.
