SQL Server on Linux

Overview of this book

Microsoft's launch of SQL Server on Linux has made SQL Server a truly versatile platform across different operating systems and data-types, both on-premise and on-cloud. This book is your handy guide to setting up and implementing your SQL Server solution on the open source Linux platform. You will start by understanding how SQL Server can be installed on supported and unsupported Linux distributions. Then you will brush up your SQL Server skills by creating and querying database objects and implementing basic administration tasks to support business continuity, including security and performance optimization. This book will also take you beyond the basics and highlight some advanced topics such as in-memory OLTP and temporal tables. By the end of this book, you will be able to recognize and utilize the full potential of setting up an efficient SQL Server database solution in your Linux environment.

Crash course in cryptography

We use cryptography every day: on the internet, mobile devices, ATM machines, and in almost every aspect of our digital life. In a nutshell, cryptography is about data scrambling and hiding, depending on the implementation and user-specific needs.

A database is the spine of every information system and is the specific target of potential data thieves. SQL Server has one of the best cryptographic set of features that we can use to create a state of the art security and privacy-aware systems.

Cryptography has two major terms:

  • Encryption: The process of creating an obfuscated message from plain text using a key
  • Decryption: The process of returning plain text from an obfuscated message using a key

From the perspective of how data is encrypted/decrypted there are two types of encryption:

  • Symmetric cryptography
  • Asymmetric cryptography
