SQL over HTTP security

Three-Tier Architecture to Protect your SQL Databases

Your SQL database will never be exposed directly to the Internet, because AceQL HTTP uses a three-tier architecture. All SQL client calls are analyzed and filtered by a configurable Servlet, the AceQL HTTP Manager. Only this Servlet can access the SQL database directly. Access to the database is granted only if the client call matches the rules defined in the Servlet.

Strong Client Authentication for Access to the SQL databases

Each client must be logged in with a username and password to gain access to an AceQL Session. The username and password are verified by the User Authentication Manager, using one of the built-in classes or your own injected Java code to authenticate the username-password pair. Once the client is logged in, an authentication session ID is built using strong cryptography. The authentication session ID is then reused at each client call to verify that the request is legitimate. A default authentication session ID builder algorithm is provided, but you may use JSON Web Tokens or define and code your own implementation.

Security Manager - Configuring SQL Firewall Rules in Java

You can configure your SQL firewall rules in Java to reinforce the protection of your databases. These rules:

• Allow filtering SQL request types, tables, Prepared Statement parameters and client usernames.
• Enable fine granularity analysis of SQL calls before allowing effective server side execution.
• Allow running code if a SQL call is discarded (example: allow immediately discarding and revoking a client username or IP address when an unauthorized SQL call is detected.)

The simplicity of use is combined with great flexibility:

• Built-in SqlFirewallManager instances may be added without any programming for DCL control, DDL control, write data control, metadata queries control. Just chain them to define the default policy.
• Automatic white lists creation by just running client applications.
• Advanced specific rules can be easily added without any programming.
• The plug-in of any existing SQL database firewall on the market is straightforward and requires only a few lines of Java code.

SQL Data Transport Security - SSL/TLS Support

All HTTP communications between the client side and the server can be encrypted with SSL/TLS.
