Greenplum Database Firewall by DataSunrise
Greenplum firewall by DataSunrise is an enterprise-class tool aimed at protecting big data. It is designed to secure databases and data warehouses on-premises and in the cloud. It protects sensitive data from external attacks, malicious insiders and the potential threat of user negligence. The firewall also enhances organization’s ability to meet compliance requirements.
The firewall is deployed in proxy mode. It scans and intercepts communication between client and database. Playing a role of an inspection point the firewall audits, logs and filters traffic, blocking queries violating security policies.
After deployment you can add learning rules so that DataSunrise will analyze incoming SQL queries and generate a list of common requests that further will be assumed safe and used to build a comprehensive security perimeter.
In the process of initial traffic processing the firewall inspects queries coming from users, output returned by the database, etc. Queries are subjected to a deep analysis and those violating security rules are blocked. When disassembling the packets the firewall differentiates objects of the target database, tables, schemas, and other relevant information.
