Which STRIDE component is associated with disputes?

The component of STRIDE that is associated with disputes is repudiation. In the context of security, repudiation refers to a situation where one party denies their actions or the validity of a transaction, leading to conflicts or disputes. This can occur when a user performs an action but later claims they did not perform it, which can compromise the integrity of the system and lead to a lack of accountability.

Repudiation can be particularly problematic in environments where transactions or communications need to be traceable and accountable. By establishing robust authentication and logging mechanisms, organizations can mitigate the risk of repudiation, ensuring that actions taken by users are recorded, and disputes can be resolved based on verifiable evidence.

The other components of STRIDE, while important, are not directly concerned with disputes. For instance, denial of service pertains to the disruption of services; spoofing identity involves impersonation; and tampering with data involves unauthorized changes to data. These aspects focus more on the integrity and availability of systems rather than on the accountability and dispute resolution that repudiation specifically addresses.
