How to Secure Azure SQL Databases



Security is the major concern for efficiently managing databases and tops the priority list for Azure solutions experts implementing Azure SQL data warehouses. It is essential to follow the Azure database security best practices to ensure the utmost security over the Cloud, including:
  • Using Firewall Rules: Firewalls are used to restrict the database access. Microsoft SQL is a relational database available as service in Microsoft Azure Cloud and allows the development of Internet-based applications. By using firewalls, you can limit the connectivity of the database through an IP address that requires users to prove their identities. This restricts the user actions on the data. You can only access the database with relevant authorization.
  • Enabling Database Authentication: SQL Database can support two types of authentications: SQL and Azure Active Directory authentication. Azure AD authentication helps you to centrally manage the identities of the database users. SQL authentication is recommended for existing applications, environments with mixed operating systems, and when users wish to connect from unknown domains. With database authentication, Azure SQL databases remain protected from unauthorized access.
  • Applying Encryption: You can secure Azure SQL Databases with TDE (Transparent Data Encryption) techniques. TDE techniques protect against malicious activity by performing encryption and decryption of databases on a real-time basis. You can even follow an in-depth defense approach by encrypting the database explicitly, even when the entire storage stands encrypted. This technique ensures the double protection of Azure SQL databases.
  • Protecting Data in Transit: Protecting data in transit requires a sound data protection strategy. Industry experts highly recommended the use of SSL/TLS protocols to ensure safe data exchange across different locations. For data moving between an on-premises infrastructure and Azure, you can rely on HTTPS and VPN for protection.
  • Scheduling Database Auditing: SQL server auditing involves scheduling server audits containing specifications for server-level events and database audit specifications for database-level events. Audit levels can be selected based on government compliance and industry installation norms. Auditing helps in maintaining regulatory compliance, understanding database activity, and gaining advanced insights into discrepancies.
  • Enabling Database Threat Detection: The SQL threat detection feature raises an alarm to notify you about potential threats detected, allowing you to take proactive action before any damage is caused.  You receive alerts regarding any suspicious database activity, vulnerabilities, SQL injection attacks, and any anomalies in the database pattern.
