Microsoft SQL Server Security

This section provides comprehensive documentation on securing Microsoft SQL Server. Learn about best practices, authentication, authorization, auditing, and data protection to ensure the integrity and confidentiality of your database.

Core Security Concepts

Understanding the foundational elements of SQL Server security is crucial for building robust and secure applications.

Authentication and Authorization

SQL Server supports various authentication modes, including Windows Authentication and SQL Server Authentication. Authorization governs what authenticated users can do within the database.

Data Encryption and Protection

Protect sensitive data at rest and in transit using features like Transparent Data Encryption (TDE) and Always Encrypted.

Auditing and Monitoring

Implement auditing to track database events and user activities, helping to detect and respond to security threats.

Threat Detection and Prevention

Explore mechanisms for detecting and preventing common database attacks.

Advanced Security Features

Dive deeper into specialized security configurations and best practices.

Compliance and Governance

Ensure your SQL Server deployments meet regulatory compliance requirements.

Securing Network Communications

Configure SQL Server to use encrypted connections to protect data as it travels across the network.

Code Examples and Tutorials

Practical examples to help you implement security features effectively.
