Invest some time into SELinux and worry less about zero-day attacks.
Conclusion

Besides Type Enforcement, SELinux includes a second model, called Role-Based Access Control (RBAC). Although I'm out of space for now, RBAC builds on the concepts we've already discussed, providing controls especially useful when real human users, as opposed to dæmons and other automated processes, are concerned.

Next time, I'll describe RBAC at length and begin going into greater depth on how actually to use SELinux, beginning with Fedora and Red Hat's “targeted” policy. Until then, be safe!

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.
