Confidentiality, Integrity, Availability (CIA triad)

The CIA triad is a fundamental concept in information security, representing three key principles: 1. **Confidentiality** ensures that sensitive information is accessible only to those authorized to view it, preventing unauthorized access. 2. **Integrity** guarantees that the information remains accurate and unaltered, ensuring that it can be trusted and is authentic. 3. **Availability** means that information and systems are accessible and functional when needed, preventing downtime and loss of access. Together, these principles help protect data and systems from threats and ensure that information is secure, reliable, and usable.
