Question
What cybersecurity measure ensures that data is not altered during transmission?
A. Confidentiality
B. Integrity
C. Availability
D. Authentication
E. Non-repudiation
Answer
B. Integrity
Explanation
Integrity ensures data remains unaltered and trustworthy during transmission.
The cybersecurity measure that ensures data is not altered during transmission is integrity.
Integrity in cybersecurity refers to the accuracy, consistency, and trustworthiness of data throughout its lifecycle, ensuring that information is not tampered with, altered, or corrupted during storage or transmission.
Integrity is one of the three core components of the CIA triad (Confidentiality, Integrity, Availability) and is critical for maintaining the reliability of data and systems.
Techniques such as hashing, checksums, and digital signatures are commonly used to verify data integrity. For example, a hash value or checksum is calculated before and after transmission; if the values match, the data was not altered.
Digital signatures not only verify the sender’s identity but also confirm that the data has not been modified since it was signed, providing strong assurance of integrity.
Compromised integrity can lead to data breaches, loss of trust, and operational failures, making it a fundamental focus in any cybersecurity strategy.
Integrity ensures that data remains unaltered and trustworthy during transmission, protecting against unauthorized modification and maintaining the reliability of information.
