CIA Triad
Definition
The CIA Triad is a widely used model for guiding information security policies. It stands for Confidentiality, Integrity, and Availability. These three principles are considered the core goals of information security.
Why It Matters
The CIA Triad provides a simple but comprehensive framework for thinking about security. Every security control and every attack can be viewed in terms of which of these three principles it upholds or violates.
Contextual Example
Confidentiality: Encryption protects data confidentiality. Integrity: Hashing ensures data integrity (that it hasn't been altered). Availability: DDoS protection services help ensure system availability.
Common Misunderstandings
- Confidentiality: Preventing unauthorized disclosure of information.
- Integrity: Ensuring information is not altered in an unauthorized way.
- Availability: Ensuring information and services are available when needed.
