Overall fixes in RHEL 5.6 number approximately 2,000, and there are 340 individual enhancements. Some of the security enhancements include updated Domain Name Service (DNS) packages – RHEL 5.6 improves the cryptographic signatures that are good for high-security installations such as in government organizations.
There is also now support for sVirt (SELinux virtualization), which allows Mandatory Access Control (MAC) profiles to be applied to virtual guests, enhancing the system’s security. In addition, ebtables, a Layer 2 firewall application, is introduced in RHEL 5.6. With this application, those using RHEL for large virtualized deployments can securely partition guest traffic with the application while configuring using multiple software bridges within RHEL.
Security enhancements aside, there is also a wealth of other improvements in Red Hat Enterprise Linux 5.6, including support for new processors and chipsets. RHEL 5 will continue to be updated until 2014 by Red Hat. For more on the update, check out SearchDataCenter.com’s news brief and Red Hat’s blog.]]>
The grant was provided by the Alfred P. Sloan Foundation to the Woodrow Wilson International Center for Scholars, which manages the CrisisCommons project. The grant will aid OSU OSL “open source” crisis efforts including hosting core CrisisCommons training resources and using open source to build a model for efficient crisis and disaster response.
CrisisCommons is a young organization – it formed after the devastating January 2010 Haiti earthquake and partnered with the OSU OSL after it needed help with its infrastructure. The organization has also aided in the Chile earthquake relief efforts, floods in Tennessee and Pakistan, and has built numerous applications using open source technology for relief efforts, including a “Person Finder” and “Tradui,” a Creole translation app.
According to Leslie Hawthorn, Open Source Outreach Manager with the OSL, the partnership on more projects like these was a no-brainer.
“Our mission is to help open source projects, and it’s even better when we can help open source projects with a mission focused on humanitarian aid and the public good,” said Hawthorn.
But why is open source playing such an important role in crisis efforts? For one, the minimal cost of open source software is huge for countries with fewer economic resources, according to Hawthorn. There are more practical, important reasons, though.
“Open source systems allow for rapid, real-time innovation by volunteers,” said Hawthorn. “CrisisCommons’ Crisis Camps are excellent examples of how hundreds of individuals can come together and contribute their skills as developers to alleviate suffering, all of which is made possible because the source code they are improving is open source.”
