Confidentiality
Definition
Confidentiality is a component of the CIA Triad that ensures information is not disclosed to unauthorized individuals, entities, or processes. It is about keeping data private and secret.
Why It Matters
Protecting confidentiality is essential for maintaining privacy and complying with data protection regulations. A breach of confidentiality can lead to identity theft, financial loss, and reputational damage.
Contextual Example
Using encryption to protect the contents of an email ensures its confidentiality. Only the intended recipient with the decryption key can read the message.
Common Misunderstandings
- Access controls, like passwords and permissions, are a primary mechanism for enforcing confidentiality.
- It is the "C" in the CIA Triad.
