What is CIA Triad?
The CIA Triad is a model designed to guide security policies within an organization. It consists of three fundamental principles: Confidentiality, Integrity, and Availability. Confidentiality ensures that sensitive information is protected from unauthorized access. Integrity guarantees that data is accurate and complete, preventing unauthorized modification. Availability ensures that authorized users have timely and reliable access to information and resources.
