 Ensuring the correctness of data inputted to a system is a fundamental aspect of data integrity within information security. Integrity refers to the trustworthiness and accuracy of data throughout its lifecycle. This means that the data has not been altered in an unauthorized manner and remains consistent, accurate, and trustworthy. It is crucial for the proper functioning of any system that relies on data to make decisions or perform operations. Measures to ensure data integrity include input validation, error checking, and data verification processes that prevent incorrect data entry, unauthorized data alteration, and ensure that the data reflects its intended state.
