Which type of attack impacts confidentiality?

Interception is a type of attack that specifically threatens the confidentiality of information. When an attacker successfully intercepts data, they gain unauthorized access to sensitive information that was meant to be kept private. This can happen through various methods, such as eavesdropping on network communications or accessing data transmissions without authorization.

The focus on confidentiality is crucial in the realm of information security, as maintaining the privacy of data is a primary goal. If an attacker intercepts information, they may reveal confidential details that should only be available to authorized individuals or systems. For instance, an intercepted email might expose personal data, financial records, or sensitive business information.

In contrast, the other types of attacks—interruption, modification, and fabrication—do not primarily target confidentiality. Interruption typically aims to disrupt service and availability, modification involves altering data to compromise integrity, and fabrication focuses on creating false data to mislead or deceive. Consequently, interception stands out as the attack that most directly impacts the confidentiality of data.
