Confidentiality - ensuring data is accessible only to authorised individuals (encryption, access controls). Integrity - ensuring data is accurate and unmodified (hashing, checksums). Availability - ensuring systems and data are accessible when needed (redundancy, backups, disaster recovery).

The CIA Triad forms the foundation of information security. Confidentiality protects sensitive data from unauthorized access. Integrity ensures data remains accurate and trustworthy. Availability guarantees that systems and data are accessible when needed by authorized users.

1. Confidentiality: Encrypting customer data in databases. 2. Integrity: Using digital signatures for legal documents. 3. Availability: Implementing load balancers and failover systems for critical applications.

Often, improving one aspect of the triad can impact others. For example, strong encryption (confidentiality) might affect system performance (availability). Security professionals must find the right balance based on organizational needs and risk tolerance.
