Essentials Spring Example

Essentials is released under version 2.0 of the Apache License

NOTE:
The Essentials libraries are WORK-IN-PROGRESS

Security

Several of the components, as well as their subcomponents and/or supporting classes, allows the user of the components to provide customized:

• table names
• column names
• collection names
• etc.

By using naming conventions for Postgresql table/column/index names and MongoDB Collection names, Essentials attempts to provide an initial layer of defense intended to reduce the risk of malicious input.
However, Essentials does not offer exhaustive protection, nor does it assure the complete security of the resulting SQL and Mongo Queries/Updates against injection threats.

The responsibility for implementing protective measures against malicious API input and configuration values lies exclusively with the users/developers using the Essentials components and its supporting classes.
Users must ensure thorough sanitization and validation of API input parameters, SQL table/column/index names as well as MongoDB collection names.

Insufficient attention to these practices may leave the application vulnerable to attacks, endangering the security and integrity of the database.

Please see the Security notices for Essentials components/README.md, as well as Security notices for the individual components, to familiarize yourself with the security risks related to using the Essentials Components:
