Twenty-Five Linux Server Hardening Tips

Wed, 22 Jun 2011 11:53:00 EDT

When it comes to having a Linux server hosted in a data center or it is not behind any kind of Firewall or NAT device there are a number of security requirements that need to be addressed. Linux servers generally come with no protection configured by default and depending on the hosting company or distro can come preconfigured with many services installed that are not required, including Web Servers, FTP Servers, Mail Servers and SSH Remote Access. The following is a compilation of various settings and techniques you can employ to harden the security of your vulnerable Linux systems. While I have tried to put them in order of the most important features first I would recommend all of these options be used on your critical production servers.

Book Review: Advanced AJAX by Shawn M. Lauriat

Mon, 14 Apr 2008 06:00:00 EDT

Because AJAX moves so much application logic from the server to the client, it forces many developers to master a wider range of web technologies than ever before. To work effectively on AJAX projects, front-end developers have to concern themselves with database performance, business logic and other server-side concerns. Back-end and middleware developers, meanwhile, have to make friends with XHTML, CSS, JavaScript and a wide range of browsers.

Fedora Software

Tue, 28 Feb 2006 09:00:00 EST

Excerpted in part from Red Hat Fedora and Enterprise Linux 4 Bible by Christopher Negus (Wiley Publishing, 2005). In its Fedora Core Linux system, the Red Hat-sponsored Fedora Project aims to only include software that is Open Source and free of reasonable patent claims. As a result, at random intervals, an article or mailing list post will exclaim how Fedora sucks because it doesn't have xyz media player, certain file system support, or other favorite that's in some other Linux.

Red Hat Fedora and Enterprise Linux 4 Bible

Sun, 18 Sep 2005 13:00:00 EDT

I was recently looking to upgrade a laptop to Fedora Core 4, which happened to happen at roughly the time I got a copy of Red Hat Fedora and Enterprise Linux 4 Bible by noted technology author Christopher Negus. During a quick scan I ran into a section that I think many Linux users, Fedora or otherwise, might fine useful, Chapter 9, using the 'Internet and the Web,' which despite the chapter heading delves into things many new Linux users might find interesting particularly 'Remote Login Copy and Execution,' which was excerpted in Volume 3, Issue 8 of LinuxWorld Magazine.

Can Linux Clusters Move into Mainstream Information Technology?

Mon, 28 Mar 2005 00:00:00 EST

The emergence of commodity supercomputing has driven clusters based on the Linux operating system into engineering and scientific research organizations that couldn't afford their own supercomputing resources before. But Linux clusters have the potential to become a hot topic in traditional information technology circles as well. The coming year may well be the technology tipping point when Linux cluster technology escapes its current home in research organizations and inhabits the traditional data center.

qmail

Thu, 10 Mar 2005 00:00:00 EST

Although postfix is popular with a number of administrators (especially those with multiple domains and many users), qmail is the unknown underdog that the experts use.
