How do you mask data in a snowflake?

What is the difference between data masking and tokenization?

Tokenization – a method of replacing sensitive data with non-sensitive placeholder tokens. … Data masking – a process that scrambles data, either an entire database or a subset. Unlike encryption, masking is not reversible; unlike tokenization, masked data is useful for limited purposes.

Is data masking reversible?

Encryption, tokenization, and data masking work in different ways. Encryption and tokenization are reversible in that the original value of the data can be derived from the obfuscated data. Data masking is irreversible if done correctly.

What is Dynamic Data Masking in Azure?

Dynamic Data Masking is a feature to limit the sensitive data to the non-privileged users by hiding the data of a column. Data is not masked and stored in the disk. Masking is applied to the result set returned to the user. … Let us see how to apply Dynamic Data Masking in the Azure SQL database using the Azure portal.

What is static data masking?

Static data masking (SDM) permanently replaces sensitive data by altering data at rest within database copies being provisioned to DevOps environments. Dynamic data masking (DDM) aims to temporarily hide or replace sensitive data in transit leaving the original at-rest data intact and unaltered.

What is test data masking?

Data masking is a data security technique in which a dataset is copied but with sensitive data obfuscated. This benign replica is then used instead of the authentic data for testing or training purposes.

When would you use dynamic data masking?

Dynamic data masking helps prevent unauthorized access to sensitive data by enabling customers to specify how much sensitive data to reveal with minimal impact on the application layer. DDM can be configured on designated database fields to hide sensitive data in the result sets of queries.

What is Dynamic Data Masking in SQL Server?

Dynamic Data Masking is a new security feature introduced in SQL Server 2016 that is used to protect sensitive data from being viewed by unauthorized users by masking the data on the result set without performing any change to the data stored in the disk.
