iSACA Cybersecurity Fundamentals Certification Practice Exam

What does integrity in cybersecurity ensure?

1. Protection from unauthorized access

2. Protection from disruptions in access

3. Protection from unauthorized modification

4. Protection from harmful actions against assets

The correct answer is: Protection from unauthorized modification

Integrity in cybersecurity primarily ensures the protection from unauthorized modification of data or information. This means that integrity mechanisms are in place to guarantee that information remains accurate and unaltered during storage, processing, or transmission, except when explicitly allowed by authorized individuals or processes. When integrity is maintained, any unauthorized attempts to change data would be detected, thus safeguarding the authenticity and reliability of that information. For instance, checksums, hashes, and digital signatures are common techniques used to verify that data has not been tampered with in transit or at rest. The focus on this aspect of cybersecurity is vital because even a small unauthorized alteration can lead to significant consequences, such as misinformation, operational failures, and loss of trust in data systems. In contrast, other concepts presented in the options address different aspects of cybersecurity. For example, protection from unauthorized access pertains to confidentiality, which restricts who can view the information. Protection from disruptions in access connects to availability, ensuring systems are functional and accessible when needed. Lastly, protection from harmful actions against assets encompasses a broader security approach, safeguarding against threats without specifically addressing data modification.
