Question

BlackTom AI · Accepted Answer

The question asks which component of the CIA triad corresponds to limiting access to information so that only authorized users can view sensitive data.
Option 1: Availability. This concept focuses on ensuring that information and systems are accessible when needed, not on who is allowed to view the data. It does not address access control to protect confidentiality.
Option 2: Integrity. This concerns maintaining the accuracy and trustworthiness of data, preventing unauthorized modification. While important for security, it does not describe restricting viewing rights.
Option 3: Authentication. This is the process of verifying a user’s identity (showing who someone is) but does not by itself enforce which data they can access once authenticated. Access control policies operate after authentication.
Option 4: Confidentiality. This is the correct choice, as confidentiality is specifically about protecting information from unauthorized disclosure and ensuring that only authorized individuals can view sensitive data. It directly addresses access restrictions and data exposure risk.
