Data Integrity practice test

Data Integrity refers to the assurance that data remains accurate, consistent, and reliable during its entire life cycle. This security concept is crucial because compromised data integrity may lead to incorrect decision-making or unauthorized modifications to the data, causing serious consequences for an organization. Data integrity can be achieved through several methods, including access controls, error detection and correction algorithms, hashing, checksums, and digital signatures. Ensuring data integrity not only offers protection from unauthorized changes but also validates the reliability and credibility of the data. Data integrity is an important aspect of overall data security, as it helps maintain trust in the organization's information and systems.
