Platform and application security: Linux distributions, AppArmor and more
Looking for the safest Linux distribution? Hardening Linux author and security expert James Turnbull ponders the field and difficulties in ranking distro's security in this Q&A . He also weighs in on security tool strength, as in AppArmor versus SELinux, and other platform and application security conundrums.
Is AppArmor suitable as an alternative to SELinux? Since SUSE is dropping support for SELinux, should an IT shop using SUSE switch distros?
James Turnbull: AppArmor is perfectly suitable as an alternative to SELinux. Indeed, if your shop already uses SUSE, then I strongly recommend investigating AppArmor before making the significant decision to migrate distributions. I believe you will find that AppArmor provides equivalent support to SELinux and with the additional benefit of being supported under SUSE, hence not requiring distribution migration.
Of course, if you have significant implementation and investment in SELinux, then potentially migration to Red Hat or another distribution that supports SELinux might be an option.
How does security differ between Linux distros? What tools are offered by commercial distros? What are the strengths and weaknesses of them?

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
