Which STRIDE component deals with denial of service attacks?

The correct choice is directly related to the concept that underpins the STRIDE threat modeling framework. STRIDE is an acronym that categorizes different types of security threats that can affect systems, and each component addresses specific vulnerabilities.

Denial of Service (DoS) attacks are specifically aimed at disrupting the availability of a service to its intended users. This aligns precisely with the focus of the Denial of Service component within the STRIDE framework. It encompasses attacks that overwhelm services, making them slow or entirely unresponsive, thereby denying legitimate users access.

Understanding this component is essential in the context of cloud security, where service availability is crucial. DoS attacks can severely impact operations, leading to potential financial losses and damage to organizational reputation. Effective identification and mitigation of such threats are key factors in maintaining robust cloud security practices.

The other components—Spoofing Identity, Repudiation, and Tampering with Data—address different security concerns. Spoofing relates to impersonating users or systems, Repudiation focuses on denying actions after they have occurred, and Tampering with Data involves unauthorized modification of data. None of these directly address the disruption to service availability that is characteristic of Denial of Service attacks.
