HowTo Build a Snort-based NSM

Here is a great step-by-step document for creating a Network Security Management infrastructure using Snort, Apache, SSL, PHP, MySQL, and BASE installed on CentOS 4, RHEL 4 or Fedora Core – with NTOP.

Introduction from Patrick Harper, CISSP, RHCT, MCSE:

This is really a deviation from what I have done before. It will start from a minimal install of CentOS 4 or RHEL 4 and will build a Snort sensor/manager. This system will start at the command line and not have X window installed unless you add it during the install. Also you can use Fedora with very little change to this doc.

The document can be downloaded from and so can a VMWare image with the NSM completely configured.

I have personally set this up without running into any issues. I strongly suggest you pre-read the document before attempting the steps so that you understand what is required of you.
