Data masking is the process of replacing sensitive data with realistic but not real data to protect it from unauthorized access or exposure. It is typically used to protect sensitive data such as personal identification numbers, credit card numbers, and other confidential information.
The process scans content and applies regular expressions to mask the sensitive information by replacing the sensitive data with a set of predetermined characters or values, such as asterisks or random characters. This makes it difficult for unauthorized users to access the sensitive data, while still allowing the data to be used for testing, development, and other purposes.
