Tutorial quote: The Web site hosting business has become more competitive in recent years. If you can find a better hosting deal, you may be able to save money by switching hosting providers. But what's the best way to move your Web site? What if you have a virtual private server (VPS) hosting several domains? What about PHP and your SQL data?

Debian Secure Your Apache With mod_security
Post date: July 16, 2006, 11:07 Category: Security Views: 2411 Comments: 0
Tutorial quote: This article shows how to install and configure mod_security. mod_security is an Apache module (for Apache 1 and 2) that provides intrusion detection and prevention for web applications. It aims at shielding web applications from known and unknown attacks, such as SQL injection attacks, cross-site scripting, path traversal attacks, etc.

In the first chapter I will show how to install mod_security on Debian Sarge, Ubuntu 6.06 LTS (Dapper Drake), and on Fedora Core 5, and in the second chapter I will describe how to configure Apache for mod_security which is independent from the distribution you're using.

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!
CentOS Installing Xen On CentOS 5.2 (i386)
Post date: November 9, 2008, 06:11 Category: Installing Views: 1935 Comments: 0
Tutorial quote: This tutorial provides step-by-step instructions on how to install Xen on a CentOS 5.2 system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called virtual machines or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.
RedHat Taking advantage of SELinux in Red Hat Enterprise Linux
Post date: April 15, 2005, 16:04 Category: Security Views: 1495 Comments: 0
Tutorial quote: The release of Red Hat Enterprise Linux 4 debuts the first commercially supported inclusion of Security-Enhanced Linux (SELinux). An installation of Red Hat's latest enterprise operating system has SELinux installed and enabled by default. In the past SELinux has been criticized for a lack of commercial support, many big sites were unable to use it due to the lack of support (Fedora Core 3 doesn't have the support that they require). Now in Red Hat Enterprise Linux 4, SELinux is a supported part of the OS, and such objections to the use of SELinux have gone away. SELinux is now widely regarded as being suitable for the largest sites.

Tutorial quote: This is a description of how to set up a secure tunnel between your MySQL Server and a locally running MySQL Administrator using Putty. By creating a secure tunnel to your MySQL server using Putty, you can grant localhost access to powerful applications like MySQL Administrator while at the same time, make your server appear as if it isn't even there. In effect, make your MySQL server disappear from the outside world.

Tutorial quote: Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT (vmx) or AMD-V (svm). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.
