What does the "CIA triad" represent in information security?

The "CIA triad" in information security stands for Confidentiality, Integrity, and Availability. This foundational model helps organizations understand and manage data security.

Confidentiality ensures that sensitive information is accessible only to those authorized to have access. This involves implementing measures such as encryption and access controls to safeguard private data from unauthorized users.

Integrity relates to the accuracy and trustworthiness of data. It ensures that data is not altered or tampered with by unauthorized individuals and is a crucial aspect to maintain trust in the information being processed and stored. Techniques such as checksums, hash functions, and data validation measures are employed to uphold data integrity.

Availability refers to ensuring that authorized users have access to information and associated assets when needed. This involves maintaining hardware and software, implementing redundancy measures, and ensuring operational continuity to prevent data loss and downtime.

Together, these three components form the cornerstone of effective information security strategies, making them critical for protecting organizational data and systems.
