Azure SQL Database Security Concepts
This document outlines the key security concepts and features available for Azure SQL Database, helping you protect your data and meet compliance requirements.
Comprehensive Security for Your Data
Azure SQL Database offers a robust set of security features built into the platform, encompassing network security, authentication, authorization, data protection, and threat detection.
- Defense in depth approach
- Continuous security updates
- Integration with Azure security ecosystem
Network Security
Control access to your Azure SQL Database by configuring network security rules. This includes:
- Firewall Rules: Restrict access to your database server by IP address or IP address range.
- Virtual Network Service Endpoints: Secure your Azure SQL Database by restricting connections from a specified virtual network.
- Private Link: Provide secure access to Azure SQL Database over a Private Endpoint in your virtual network.
Authentication and Authorization
Securely identify and grant permissions to users and applications accessing your database.
- SQL Authentication: Use username and password for authentication.
- Azure Active Directory (Azure AD) Authentication: Leverage your Azure AD identity for centralized identity management and single sign-on. This includes support for multi-factor authentication (MFA).
- Role-Based Access Control (RBAC): Define granular permissions for users and groups at the database and server levels.
Data Protection
Protect sensitive data both at rest and in transit.
- Transparent Data Encryption (TDE): Encrypts your data files and transaction logs at rest.
- Always Encrypted: Protects sensitive data in the database, such as credit card numbers, by encrypting them on the client side and storing them encrypted.
- Dynamic Data Masking: Restricts sensitive data by obfuscating it to non-privileged users.
- SSL/TLS Encryption: Ensures secure data transfer between your application and Azure SQL Database.
Threat Detection and Monitoring
Proactively identify and respond to potential threats.
- Azure Defender for SQL: Provides advanced threat protection capabilities, including vulnerability assessment and anomaly detection.
- Auditing: Track database events and logs to monitor access and detect suspicious activities.
- Security Center Integration: Leverage Azure Security Center for a unified view of your security posture and recommendations.
Compliance
Azure SQL Database helps you meet various industry and regulatory compliance standards, such as GDPR, HIPAA, and PCI DSS, through its built-in security features and certifications.
