Data integrity refers to the accuracy and consistency of data throughout its lifecycle, ensuring that information remains unaltered and reliable. This concept is fundamental in information security, as it encompasses the methods and processes used to maintain the correctness of data. Protecting data integrity involves various practices, such as implementing error-checking methods, access controls, and logging changes to data. These measures help prevent unauthorized alterations and ensure that data remains authentic and trustworthy.

The other choices relate to important aspects of data protection but do not directly define data integrity. For instance, encrypting data enhances confidentiality and protects against unauthorized access, while backing up data is about safeguarding against loss or corruption. Securely erasing data focuses on preventing its recovery after deletion, which is essential for maintaining privacy but not inherently tied to the integrity of the data itself. Thus, among these options, the first choice most accurately captures the essence of data integrity in information security.
