Which security control is designed to protect against an individual falsely denying an action?

• A. AU-8 Auditing
• B. AU-10 Non-repudiation
• C. AC-3 Access Enforcement
• D. IA-5 Authenticator Management

Answer: (B)

Non-repudiation is a critical security control that ensures an individual cannot deny the authenticity of their actions or transactions. This control is essential in maintaining accountability and traceability in digital interactions, particularly within systems handling sensitive information. The concept of non-repudiation typically involves mechanisms such as digital signatures or audit logs that securely record the actions taken by users. By employing these mechanisms, organizations can verify that a particular action was indeed executed by a specific user, thus preventing that user from later claiming they did not perform the action. This is vital for establishing trust in digital communications and transactions, especially in environments subject to regulatory compliance. In contrast, auditing, access enforcement, and authenticator management each serve different purposes in the broader context of information security. Auditing focuses on the collection and review of records to ensure compliance and detect anomalies. Access enforcement regulates who can access certain resources based on permissions. Authenticator management involves the processes for issuing, maintaining, and revoking credentials used for access control. While each is important in its own right, none specifically address the prevention of denial of actions like non-repudiation does.
