In this tutorial, we will teach you how to use a Iptables with shared private networking to simulate the network traffic isolation that a true private network can provide.

In this tutorial you’ll learn how Suricata signatures are structured, and some important options that are commonly used in most rules. Once you are familiar with how to understand the structure and fields in a signature, you’ll be able to write your own signatures that you can combine with a firewall to alert you about most suspicious traffic to your servers, without needing to use other external rulesets.
