What is obfuscation in SQL?

The obfuscation renders the source code bodies of the SQL functions, SQL procedures, and triggers unreadable, except when decoded by a database server that supports obfuscated statements.

What method can be used to obfuscate data in SQL Server?

SQL Server 2016 and Azure SQL DB now offer a built-in feature that helps limit access to those particular sensitive data fields: Dynamic Data Masking (DDM). DDM can be used to hide or obfuscate sensitive data, by controlling how the data appears in the output of database queries.

How do you obfuscate data in a database?

Three of the most common techniques used to obfuscate data are encryption, tokenization, and data masking. Encryption, tokenization, and data masking work in different ways. Encryption and tokenization are reversible in that the original values can be derived from the obfuscated data.

How do you mask sensitive data?

Here are a few common data masking techniques you can use to protect sensitive data within your datasets.

  1. Data Pseudonymization. Lets you switch an original data set, such as a name or an e-mail, with a pseudonym or an alias.
  2. Data Anonymization.
  3. Lookup substitution.
  4. Encryption.
  5. Redaction.
  6. Averaging.
  7. Shuffling.
  8. Date Switching.

What is difference between hashing and encryption & obfuscation?

Hashing: This is meant to provide verification of the integrity of something (a file for instance). Encoding: This is changing the format of something into a different format. Encryption: This is a method for controlling access to data. Obfuscation: This is a method for making something harder to see or understand.

What is the difference between data obfuscation and data encryption?

Obfuscation, also referred to as beclouding, is to hide the intended meaning of the contents of a file, making it ambiguous, confusing to read, and hard to interpret. Encryption is to actually transform the contents of the file, making it unreadable to anyone unless they apply a special key.

Are obfuscated servers safe?
