Drastically Speed up your Linux System with Preload

,----[ Quote ]
| Preload can provide a great improvement in application startup time; since
| most modern machines have a good deal of memory to spare, Preload puts this
| RAM to good use. I highly recommend installing Preload on your desktop
| machine, and although it may take a little while for the daemon to learn your
| habits before your see any real performance improvement, it's a great tool
| that increases the speed of your system while staying in the background, out
| of your way.

SELinux

,----[ Quote ]
| We all appreciate that when we turn on our Linux systems they're pretty
| secure. Thanks to continuing improvements to SELinux, it is increasingly easy
| for users to take advantage of this powerful security tool. Read on to find
| an interview with Daniel Walsh, the principal developer of SELinux in Fedora
| from Red Hat, where he tells us more about what SELinux does and how it's
| improved in Fedora 8. At the end of the article are some screenshots which
| show-off the new policy creation GUI. * * *

Linux Application Hardening

| When we talk about Linux hardening, we typically mean runtime
| application hardening to improve application reliability, leading to expected

SELinux — is it really too complex?

,----[ Quote ]
| What I discovered is that part of SELinux’s current dilemma is more easily
| fixable than the other, because it has nothing to do with technological chops
| and everything to do with public perception. Jim Klein, the director of
| information services and technology at the California-based Saugus Union
| School District, put it best: “The biggest problem for SELinux is mindshare,” *
| Klein told me. “It developed a stigma early on due to the lack of tools for
| configuration and troubleshooting, which led people to simply turn it off.”
| Currently, Klein is one of the many IT guys who has the SELinux switch in
| the “off” position. * * *

SELinux vs. OpenBSD's Default Security

,----[ Quote ]
| Darrin Chandler suggested, "security should not be grafted on, it should be
| integrated into the main development process. I'm sure the patch maintainers
| are doing their best, but this doesn't change the fundamental flaw in the
| process. It's not a flaw of their making, it's inherent in the situation. But
| it's still a flaw." * *

Is SE Linux only for Linux?

,----[ Quote ]
| Sun is also apparently considering adding type-enforcement to Solaris. It’s
| yet to be seen whether this happens and if so whether it is compatible with
| SE Linux. *
|
| So it seems that a significant portion of the SE Linux code base is portable,
| and in particular the user-space code should port well. The interfaces for
| and methods labelling files etc should port well between platforms. Therefore
| I recommend not having SE Linux code split into Linux specific trees and
| instead having a compile option to enable SE Linux support. * *

Five ways SELinux may surprise you

,----[ Quote ]
| What you may not realize is all the ways SELinux is being applied to
| a variety of security challenges. Just because SELinux was initially
| developed by the military does not mean it is only useful to
| complicated security problems and large-budget organizations -- SELinux
| is for you too. And despite what you might have heard, you don't need to
| be an expert to reap the benefits of SELinux's powerful protection
| features.
