I really can’t wait until I can get my hands on the new Snort Intrusion Detection and Prevention Toolkit book from Syngress.
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.
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.
An excellent article is available over at Howto Forge on “A multi-stage approach to securing your email communication”
When speaking of mail server-related security, one tends to limit the issue to message applied security measures, and even more to Antivirus and Antispam protection. This is however only one stage in the more complex process of securing your server. This article aims at identifying and explaining all security layers, highly important when choosing a certain mail server and consequently when configuring and using it.
