Medusa DS9 Security System

It's not a panacea, it's not perfect, but it is a very interesting piece of software.
What Next?

The Medusa development team is working heavily on it. They want to make Medusa a bit more object-oriented. That means you'll be better able to handle system objects to set their properties. They want to port it to other platforms (currently, only Linux/Intel is supported) and create a front end which will allow the administrator to create and configure security schemes more easily.

Medusa was not tested extensively on multiprocessor systems, but those who tried it didn't report any serious problems. Medusa needs a bit more detailed and better documentation. Constable configuration scripts can be truly complicated, so some form of automatic configurator will probably appear in future versions. You can write your own front end to Medusa, which can create the needed security model and implement it by using Constable configuration.

Medusa is a very interesting system, not only with security functionality. It will probably never appear in the official kernel, but can be used as an add-on package to increase the security of your Linux system.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
