What is the consequence of a breach of integrity in information security?

A breach of integrity in information security primarily results in compromised data trustworthiness. Integrity ensures that data remains accurate, reliable, and unaltered by unauthorized individuals. When integrity is breached, it indicates that the information may have been modified or tampered with, leading to discrepancies that can misinform decisions and damage the credibility of the data. This undermines the overall trust in the system and the information it holds.

While unauthorized access can be a factor in integrity breaches, it more directly pertains to confidentiality rather than integrity itself. Similarly, while issues of availability may arise due to other factors, they are not directly indicative of a breach of integrity. Loss of confidentiality refers to unauthorized access to sensitive information, unrelated to the integrity of that information. Conversely, when data integrity is lost, the trustworthiness of the data is fundamentally compromised, making it the most relevant consequence.
