Which security measure breaches the condition of integrity through data alteration?

Code injection refers to an attack technique where an attacker introduces or "injects" malicious code into a software application, often through input fields. This can lead to unauthorized actions being performed on that application, including the alteration of data. Since integrity is defined as the assurance that information is accurate and trustworthy, any unauthorized modification of data directly breaches this condition.

In the context of security, integrity ensures that data remains unchanged except through authorized means. A successful code injection attack can manipulate data at rest or in transit, impacting its integrity by changing it in ways that were not intended by legitimate users or system designers. This is why code injection is recognized as a significant threat to data integrity, as it allows for undetected changes to the information being processed.
