Application Roles4:47
Understand the use of application roles to control access based on application context.
Schema-Based Security3:52
Discover how schema-based security organizes database objects and controls user access effectively.
Creating Strong Password Policies for SQL Server2:54
In this lecture, we’ll explore why strong passwords are crucial and how you can implement effective password policies in your SQL Server environment.
Authentication and Authorization

Section Overview2:42
What you will be learning in this section.
Encryption at Rest - Transparent Data Encryption (TDE)7:12
Learn how TDE protects data at rest by encrypting SQL Server database files.
Encryption in Transit - SSL/TLS7:58
Explore methods to secure data in transit with SSL/TLS encryption.
Always Encrypted6:37
Understand how Always Encrypted secures sensitive data at the column level.
Data Masking3:33
Learn how data masking obfuscates sensitive data to limit exposure to unauthorized users.
Dynamic Data Masking12:29
Dive into dynamic data masking to enforce data visibility rules without altering the data itself.

In this lecture, we will explore how to secure SQL Server when running in cloud and hybrid environments.
Privileged Access Management (PAM) for SQL Server3:59
In this lecture, we'll explore Privileged Access Management, or PAM, in SQL Server. Privileged accounts, like sysadmin logins, are powerful but also pose the highest security risks if they’re misused or compromised. We'll look at common challenges, best practices to minimize and control privileged access, how to implement Just-in-Time access, and why auditing is essential.
Operational Security and Advanced Best Practices

Requirements

Basic knowledge of SQL Server administration is recommended.
Access to a computer with SQL Server installed (optional).
