A loss of __________ is the unauthorized disclosure of information.

Question

BlackTom AI · Accepted Answer

Confidentiality refers to restricting access to sensitive information so only authorized individuals may view it; a loss of confidentiality means that information has been disclosed to unauthorized parties.

Relevant knowledge points and concepts:
- The core security properties are commonly summarized by the CIA triad: Confidentiality, Integrity, and Availability (plus related concepts such as Authenticity and Reliability).
- Confidentiality = prevention of unauthorized disclosure or exposure of data.
- Integrity = prevention of unauthorized modification or tampering of data.
- Authenticity = assurance that data or an identity is genuine (origin and identity verification).
- Reliability = consistency and dependability of a system or service (often overlapping with availability).

Step-by-step reasoning:
1. Identify the phrase in the question: "unauthorized disclosure of information." That phrase literally describes data being revealed to parties who should not see it.
2. Match that definition to the security concepts: unauthorized disclosure is the definition of a breach of confidentiality.
3. Eliminate other choices by checking their definitions against "unauthorized disclosure":
   - Authenticity concerns verifying that a message or user is genuine; it does not specifically address disclosure of content.
   - Integrity concerns whether the content has been altered or tampered with; a change in content is different from disclosure of content.
   - Reliability concerns consistent operation and performance; it does not address secrecy of information.
4. Therefore the option that directly corresponds to unauthorized disclosure is "confidentiality."

Why the correct answer is correct:
Unauthorized disclosure is the textbook definition of a loss of confidentiality: when secrets, personal data, or protected information are exposed to unauthorized parties, confidentiality has been compromised. Controls such as encryption, access controls, and data classification are used to protect confidentiality.

Why the other options are incorrect:
- Authenticity: relates to proving identity/origin, not disclosure.
- Integrity: relates to preventing unauthorized changes, not exposure.
- Reliability: relates to system dependability, not secrecy.

Conclusion: The correct answer is confidentiality, which matches the provided answer.
