AppArmor

OpenSuse

I am tempted to use this distro..has got more sleek graphical features as compared to ubuntu, and also has got AppArmor

AppArmor is an application security tool designed to provide an easy-to-use security framework for applications. AppArmor proactively protects the operating system and applications from external or internal threats, even zero-day attacks, by enforcing good behavior and preventing even unknown application flaws from being exploited. AppArmor security policies, called “profiles”, completely define what system resources individual applications can access, and with what privileges. A number of default profiles are included with AppArmor, and using a combination of advanced static analysis and learning-based tools, AppArmor profiles for even very complex applications can be deployed successfully in a matter of hours.
