Which item will be attacked by a DoS attack?

Correlation is a log analysis technique used in SIEMs to identify patterns across events, not a CIA triad property and not a target of DoS attacks.

Availability is the CIA triad property that ensures resources are accessible to authorized users when needed. A DoS attack directly undermines this by flooding a target with traffic or exploiting vulnerabilities to exhaust system resources, making services unreachable for legitimate users. All forms of DoS - volumetric, protocol, or application-layer - share the singular goal of denying service.

Integrity refers to the accuracy and trustworthiness of data; DoS attacks do not modify or corrupt stored or transmitted data.

Confidentiality protects data from unauthorized disclosure; DoS attacks do not aim to expose or exfiltrate sensitive information.
