The three concepts of cyber security

The foundation of cyber security basics lies in the CIA triad, which stands for confidentiality, integrity and availability. These three concepts of cyber security form the basis of protecting sensitive information and ensuring digital systems can operate securely.

1. Confidentiality

Within the CIA triad, ‘confidentiality’ refers to the assurance that data and information are accessible only to authorised persons. It involves strict security measures like encryption and access controls, which are deployed to prevent unauthorised access and data breaches.

2. Integrity

Integrity is all about keeping the data accurate and unaltered during transfers and storage. Any unauthorised modification or tampering with data will compromise its integrity, potentially leading to serious consequences.

3. Availability

Availability ensures that systems, data and resources are accessible and usable by authorised individuals around the clock. Protection against denial-of-service (DoS) attacks and system failures is crucial to maintaining availability.
