In the context of cyber security, what does non-repudiation provide?

Non-repudiation in the context of cybersecurity provides the assurance of accountability. This means that it ensures that a person or entity cannot deny the authenticity of their signature or the sending of a message, thereby holding them accountable for their actions. This is crucial in cybersecurity, as it aids in establishing trust in digital communications and transactions.

Through mechanisms such as digital signatures and logs, non-repudiation helps to confirm that a particular action was taken by a specific individual or system, which is essential for legal and security purposes. In scenarios like financial transactions or contractual agreements, non-repudiation ensures that all parties involved are answerable for their commitments, reducing the likelihood of disputes and enhancing the integrity of the interactions.

The other options focus on different aspects of cybersecurity; for example, denying an action contradicts the principle of non-repudiation, while data integrity and encryption are related to maintaining accurate data and safeguarding information, respectively. Although they are vital elements of cybersecurity, they do not encompass the key feature of accountability that non-repudiation specifically addresses.
