The Chapter 7, Writing Stored Procedures, was all about stored procedures and writing server-side code. After being introduced to many important topics, it is now time to shift to PostgreSQL security. Here, we will learn how to secure a server and configure permissions.

The following topics will be covered in this chapter:

• Configuring network access
• Managing authentication
• Handling users and roles
• Configuring database security
• Managing schema, tables, and columns

By the end of the chapter, we will be able to configure PostgreSQL security in a professional way..
