Explanation

Data masking is used to permanently replace sensitive information with symbols or random characters. This approach enhances data security by preventing the accidental exposure of sensitive data. Once masking is applied, the new data may be in the same format as the original data; however, this is not a requirement. For example, a Social Security number may be masked with symbols in order to appear in this manner: --***. Data encryption is not used to permanently replace sensitive information with symbols or random characters. Data encryption is used to encode data to protect it from unauthorized access during transmission or storage. Only users with the encryption key can decrypt the data. Data transmission is not used to permanently replace sensitive information with symbols or random characters. Data transmission is the process that is used to transfer or move data from one system to another or from one storage location to another. Data retention is not used to permanently replace sensitive information with symbols or random characters. Data retention is used to control how long and in what forms data can be stored.
