CSO — Free and open-source software (FOSS) is everywhere. Its offerings span far and wide in the technology industry. The networking space is an excellent example of FOSS, with feature-packed firewalls, routers, VPNs and even UTMs, for nearly every need. In this article I will introduce you to a few of the commercially-supported open-source network security options currently available in the marketplace today. With open-source networking you can enjoy the benefits of lower costs, greater security, flexibility, extensibility and full enterprise support. Here are three examples.

EndianEndian is a feature-rich, unified threat management (UTM) system that offers a stateful firewall, VPN (IPSec/OpenSSL), gateway anti-malware, anti-spam, QOS/Bandwidth Management, IPS and proxy functionality. It is available as a software solution to build on your own hardware or a variety of optimized appliances that scale to meet your network security needs. Like all other competitive offerings in this space, the community edition offers core functionality with the commercial version offering even more features; plus commercial support.

The Endian web-based administrative interface is slick and easy to use. Its dashboard feature offers a real time comprehensive view of your Endian system and the network it is protecting. Endian also offers a centralized management feature, "Endian Network," a centralized web-based management/monitoring solution for multiple Endian products. The Endian Hotspot add-on module supports the creation of a secure wireless hotspot by allowing for captive portal, secure wireless via SSL VPN, a dedicated ticketing system, and RADIUS. Endian offers a great balance between a rich feature set and functionality.

A true EDW provides a single 360-degree view of the business and a powerful platform for a wide spectrum of business intelligence tasks ranging from predictive analysis to near real-time strategic and tactical decision support throughout the organization. Ensuring the EDW will get the desired performance and will scale out as your data grows you need to get three fundamental things correct, the hardware configuration, the physical data model and the data loading process. By correctly designing these three corner stones you will be able to create an EDW that can seamlessly scale without constant tuning or tweaking of the system.

By using the Oracle Exadata Database Machine as your data warehouse platform you have a balanced, high performance hardware configuration. This paper focuses on the other two corner stones, data modeling and data loading, providing a set of best practices and examples for deploying a data warehouse on the Oracle Exadata Database Machine.
