Security wars: Novell SELinux killer rattles Red Hat

Filed under
Linux

Novell Inc. of Provo, Utah, has released the source code for its recently acquired open-source Linux security application, AppArmor, and has also set up a project site in hopes of attracting outside developers to further refine the program. The release of the software has sparked debate in the open-source community, however. Novell stressed that AppArmor is easier to use than another open-source program called SELinux.

First developed by the National Security Agency, SELinux tackles the same job of mandatory access control (MAC) with an unrelenting thoroughness, though it has a reputation for being difficult to manage. "There needs to be a better way to deploy [MAC] so that the average systems administrator doesn't need to go through three weeks of training," said Frank Rego, products manager for Novell. Some observers fear that the AppArmor project will fracture the open-source development community around the demanding science of MAC. "In my opinion, Novell wants to split the market," said Dan Walsh, the principal software engineer of Red Hat Inc. of Raleigh, N.C. Both Red Hat and Novell offer enterprise class Linux distributions. "Rather than working with the open-source community [on SELinux], Novell has thrown out its own competing version." Novell acquired AppArmor last May when it purchased Immunix Inc., which developed the software. Novell has made the application, along with its source code, freely available on the site under the GNU Public License.

Firefox OS media-casting stick strikes Kickstarter gold

The first Firefox OS based media player has arrived on Kickstarter, in the form of a $25 open-spec HDMI stick that supports Chromecast-like content casting. The Matchstick, which has already zoomed past its Kickstarter campaign’s $100,000 funding goal, with 28 days still remaining, was teased back in June by Mozilla developer evangelist Christian Heilmann. The unnamed prototype was billed as an open source HDMI stick that runs Mozilla’s Linux-based Firefox OS and offers casting capabilities. Few details were revealed at the time except that the device used the same DIAL (DIscovery And Launch) media-casting protocol created by Netflix and popularized by Google’s Chromecast. Read more

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more
