Friday Spotlight: Tips for Hardening an Oracle Linux Server

Happy Friday!

One of the things I like about our Friday Spotlight is not only do we talk about new things, it also gives us an opportunity to highlight older material that is still valuable. That's the case with this week's spotlight, which is about an article from 2012 that covers tips for hardening an Oracle Linux server. If you've come to Oracle Linux in the last couple of years, you might not have seen this, and it's just as a relevant today as it was then.

This in-depth article covers minimizing active services, locking down network services, managing users and authentication, and much more. If you're a Linux administrator, you might want to consider adding this article to your Reading List, saving to Pocket or Evernote, or whatever mechanism you use to hold on to good resources.

Oracle Linux Friday Spotlight - December 6, 2013

Happy Friday!

By now, you've probably heard about the release of Oracle Linux 6.5. One really cool thing about this release is that Unbreakable Enterprise Kernel Release 3 is installed by default, meaning you get to use all the great features of UEK R3 without needing to do a separate installation. And are there a lot of great features in UEK R3! So, our spotlight this week is on the release notes for the latest version of Oracle's Unbreakable Enteprise Kernel.

Unbreakable Enterprise Kernel Release 3 release notes

You'll learn about Control Groups, Linux Containers, DTrace, additional crypto options, improved diagnostics, the updated btrfs, better memory management, more networking options, improvements for performance, security, storage, and much more.

See you next Friday!

This week we issued a second part,Tips for Securing an Oracle Linux Environment, which focuses on the operational part: detecting intrusion attempts, auditing and keeping systems up-to date and protected.

If you manage Oracle Linux systems in your environment, check out these articles for some invaluable hints and suggestions on how to improve and maintain security of these servers!
