Security Fundamentals Professional Certification (SFPC) Practice Test

If there was a loss in non-repudiation, what impact would this have on information assurance?

1. Data is no longer reliable, accurate, nor trusted

2. Data may potentially be available to unauthorized users via electronic form

3. General communications are no longer trusted

4. Potential of unauthorized access to classified data

The correct answer is: Data may potentially be available to unauthorized users via electronic form

In the context of information assurance, non-repudiation is crucial because it ensures that parties in a communication cannot deny the authenticity of their signatures or the sending of messages. A loss in non-repudiation fundamentally impacts the reliability and accuracy of the information exchanged. Choosing the impact that data may potentially be available to unauthorized users via electronic form reflects a critical consequence of failing to ensure non-repudiation. When non-repudiation is compromised, it may indicate that secure identification and verification mechanisms are not functioning effectively. This can lead to situations where data authenticity cannot be confirmed, increasing the risks of unauthorized access and exploitation of sensitive information. While the other choices illustrate negative outcomes related to security, the correct answer specifically addresses the direct consequence of non-repudiation loss concerning data availability to unauthorized users. This highlights the broader concern of ensuring proper control measures and auditing are in place to prevent data breaches and maintain overall information assurance.
