When accessing your database from an externally hosted SaaS Server, follow these steps to ensure your data is secure. You may also wish to consider one or all of these step even when using the in-house version if you feel your intranet is not secure.

Using the Database Connector's security mechanism, combined with only accepting SSL connections to the database connector from the web application container, will prevent unauthorized access to your database queries. The steps below describe how to secure your data.

On this page:

Configure SSL

The database connector does not have any specific configuration to handle SSL. Since it runs inside the Servlet container, it is typically the responsibility of the container to handle this layer of security. In any case, here is what we have done for customers that needed SSL and were using Tomcat: 

SSL (Secure Socket Layer), is a technology which allows web clients and web servers to communicate over a secured connection. This means the data being sent is encrypted by one side, transmitted, and then decrypted by the other side before processing. This is a two-way process, meaning that both the server AND the client encrypt all traffic before sending out data.” The basic steps:

Configure SSL for Standalone Database Connector

  1. Get a SSL Certificate. We recommend you get a certificate with PKCS12 (.pfx or .p12) format and SHA2 encryption.
  2. Edit <connectorInstallationDirectory\config\dbconnector.properties to add the SSL to the keystore. Example:

    # Customize the DbConnector here
  3. Browse https://<host>:<port>/database/status to check the status of the connector. Note: You may see a warning about an invalid cert, however you will get the status page if you 'ignore' and go past it.

The queryKey attribute

The queryKey attribute enables a password authentication mechanism that limits query execution to only those who know the queryKey password string. Every HTTP request that is sent to the database connector to execute that query must contain the key. The connector will deny all requests that do not contain the key.
For example, given the configuration below:

<query name="customers" queryKey="abc123"> 
    <!-- maps to the http GET method --> 
            SELECT * FROM customers WHERE customerId='{customerId}'

 A valid request would be: http://localhost:8082/database/myStore/customers?queryKey=abc123&customerId=23434

SQL Injection Protection

The  Database Connector automatically protects your data from Injection Attacks. No configuration is required for this security measure.

Database Password Security

While you cannot encrypt the database password in the <frevvo-home>\tomcat\conf\dbconnector.properties file, you can provide added security using one of the following methods:

  1. Define the data source at the container (tomcat) level for some added security. Please see this documentation which explains how.
  2. Store password as an OS Environment Variable and reference that variable in the dbconnector.properties file. See Secure Passwords in Tomcat for details.
