The integrity principle of information security refers specifically to the accuracy and trustworthiness of information. This principle ensures that data is not altered or tampered with by unauthorized individuals, which is critical for maintaining the validity and reliability of information over its entire lifecycle. Integrity encompasses mechanisms and practices that protect data from unauthorized modifications, confirming that the information remains consistent and accurate.

When information is accurate, it not only retains its correctness but also mitigates risks related to misinformation that can arise from unauthorized access or alteration. This principle is vital in contexts such as financial records, legal documents, and personal data, where even minor alterations can lead to significant consequences.

While other principles related to information security, such as availability, confidentiality, and legal protection, are also crucial, they do not address the concept of integrity directly. Proper classification, legal protection, and retrievability are important but do not explicitly capture the essence of ensuring that information remains accurate and untampered with, which is the core focus of the integrity principle.
