What is personally identifiable information that must be safeguarded from unauthorized access?

Personally Identifiable Information (PII) refers to any data that can be used to identify a specific individual. Safeguarding PII is critical to protect individuals’ privacy and prevent identity theft. A driver’s license number (B) is considered PII because it is unique to an individual and can be used to confirm their identity. Other examples of PII include social security numbers, passport numbers, and financial account numbers. It is important to protect such information from unauthorized access to maintain personal privacy and security.
