Final answer:
When a Supplier Identification Number is altered, the integrity of that data is compromised. Integrity is crucial as it maintains the accuracy and consistency of the data's lifecycle. Breaches of integrity can lead to significant repercussions including financial losses and a decline in public trust in various institutions.
Step-by-step explanation:
When someone maliciously changes one digit of your Supplier Identification Number, you lose Integrity. This is because altering any part of your data in an unauthorized manner affects the overall accuracy and reliability of the data. In the context of information security, integrity refers to the maintenance of, and the assurance in, the accuracy and consistency of data over its entire lifecycle. The change means that the data no longer represents the truth and therefore cannot be trusted.
Instances of identity theft, financial theft, and other security breaches such as power shutdowns, and election interference underline the consequences that can stem from compromised data integrity. Such breaches can lead to chaos and substantial financial costs for individuals and organizations alike. Moreover, these breaches often result in a loss of public trust in institutions such as banks, hospitals, and government agencies, further highlighting the importance of preserving data integrity.
