Concept of Cyber Security

Cybersecurity refers to the practice of ensuring the confidentiality, integrity, and availability of information. These three points are known as the CIA Triad.

Essentially, the CIA Triad is a cybersecurity principle developed to help individuals formulate various aspects of information technology security. This model represents the concept of cybersecurity.

1. Confidentiality

Confidentiality in cybersecurity is all about keeping information private and ensuring that only authorized people have access to it. Just like we keep personal secrets to ourselves or share them only with trusted individuals, cybersecurity employs various techniques to protect sensitive data from falling into the wrong hands. Encryption is one such technique that transforms information into a secret code, making it unreadable to unauthorized users. Access controls, like username and password requirements or biometric verification, act as virtual locks, granting access only to those with the right credentials. By safeguarding confidentiality, cybersecurity prevents data breaches and information theft, ensuring that your private details remain safe and secure.

2. Integrity

Integrity ensures the trustworthiness and accuracy of data. Imagine reading information from a reliable source like a textbook or listening to a knowledgeable teacher; you expect the information to be accurate.
