Static and Dynamic Data Masking: What You Need to Know

Correct Answers: B and C

The below table highlights the differences between Static Data Masking and Dynamic Data Masking.

Option A is incorrect.

Dynamic data masking takes place on the original database whereas static data masking takes place on a copy of the database.

Option B is correct.

Dynamic data masking takes place on the original database whereas static data masking takes place on a copy of the database.

Option C is correct.

In Static Data Masking, the mask takes place at the storage level while in the case of dynamic data masking, the mask takes place on the fly at query time.

Option D is incorrect.

The given statement is not true.

Option E is incorrect.

Only in static data masking, all users have access to the same masked data.

In Dynamic Data Masking, the mask varies depending upon the user's permission.

Static Data Masking and Dynamic Data Masking are two data masking options offered by Microsoft Azure. Both are used to protect sensitive data by hiding it from unauthorized users, but they work differently.

Static Data Masking: Static data masking is a method of masking sensitive data in a database. It involves creating a copy of the original database and masking the sensitive data in the copy. The original database remains unchanged. Static data masking is typically used in situations where the database is not frequently updated or where the sensitive data does not change frequently.

A. The statement "Static data masking takes place on the original database whereas dynamic data masking takes place on a copy of the database" is not true. The opposite is true, static data masking takes place on a copy of the database.

C. The statement "In Static Data Masking, the mask takes place at the storage level while in the case of dynamic data masking, the mask takes place on the fly at query time" is true. Static data masking replaces the original data with masked data at the storage level and masks the entire copy of the database.

E. The statement "In static as well as Dynamic Data Masking, all users have access to the same masked data" is not necessarily true. With static data masking, all users who access the copy of the database will see the same masked data. However, with dynamic data masking, users may have different levels of access to the data, based on their permissions.

Dynamic Data Masking: Dynamic data masking is a method of masking sensitive data in a database. It involves masking sensitive data on the fly, as it is being queried by users. Dynamic data masking is typically used in situations where the database is frequently updated or where the sensitive data changes frequently.

B. The statement "Dynamic data masking takes place on the original database whereas static data masking takes place on a copy of the database" is not true. The opposite is true, dynamic data masking takes place on a copy of the database.

D. The statement "In Dynamic Data Masking, the mask takes place at the storage level while in the case of static data masking, the mask takes place on the fly at query time" is not true. The opposite is true, dynamic data masking masks sensitive data on the fly at query time, and static data masking masks the entire copy of the database at the storage level.

E. The statement "In static as well as Dynamic Data Masking, all users have access to the same masked data" is not necessarily true. With dynamic data masking, users may have different levels of access to the data, based on their permissions.

In summary, static data masking and dynamic data masking are two different methods of masking sensitive data in a database. Static data masking creates a copy of the database and masks the entire copy, while dynamic data masking masks sensitive data on the fly as it is being queried by users. Both methods have their advantages and disadvantages and should be chosen based on the specific needs of the organization.
