Introduction

This video explains the CIA Triad, a fundamental concept in IT security. It clarifies the triad's components—Confidentiality, Integrity, and Availability—and how they relate to protecting information. The video also differentiates the IT security term from the Central Intelligence Agency (CIA).

Key Takeaways

• Confidentiality: Protecting sensitive information from unauthorized access. Methods include encryption and access controls.
• Integrity: Ensuring data remains unchanged during transmission and storage. Methods include hashing and digital signatures. Nonrepudiation provides proof of the data's origin and integrity.
• Availability: Guaranteeing reliable access to data and systems for authorized users. Techniques include fault-tolerant systems and regular patching/updates.
