Maintaining information as accurate, trustworthy, and free from tampering is the idea of integrity. It’s the principle that data should not be altered by unauthorized people or processes and must stay in its intended state from creation through storage and transmission to use. In security models like the CIA triad, this focuses specifically on preserving the correctness and trustworthiness of information. Data security is broader, covering protections in general rather than the specific goal of keeping data unaltered. Data integrity describes the data’s own correctness and consistency as a property, not the guiding rule itself. Confidentiality centers on preventing disclosure. So the term that best describes ensuring information remains accurate and untampered is the Principle of Integrity. In practice, this is reinforced with hashes, digital signatures, and audit trails to detect and prevent unauthorized changes.
