Suricata is a flexible, high performance Network Security Monitoring (NSM) tool that can detect and block attacks against your network.

This series will explore how to install Suricata on various operating systems, how to understand and write your own signatures to detect malicious or unknown traffic, and how to configure Suricata in both Intrusion Detection (IDS) and Intrusion Prevention (IPS) modes.

Once you have Suricata configured and running on your network, you’ll learn how to build your own Security Information and Event Management (SIEM) tool on top of the data that Suricata collects.

Suricata is a Network Security Monitoring (NSM) tool that uses sets of community created and user defined signatures (also referred to as rules) to examine and process network traffic. Suricata can generate log events, trigger alerts, and drop traffic when it detects suspicious packets or requests to any number of different services running on a server.

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.

In this tutorial you will learn how to configure Suricata’s built-in Intrusion Prevention System (IPS) mode. When you enable IPS mode, Suricata can actively drop suspicious network traffic in addition to generating alerts. Once you know which signatures you would like to use in IPS mode, you’ll convert their default action to drop or reject traffic. With your signatures in place, you’ll learn how to send network traffic through Suricata using the netfilter NFQUEUE iptables target.

In this final tutorial in the series, you will create custom Kibana rules and generate alerts within Kibana’s SIEM dashboards. Once you have rules in place and understand where and how to filter Suricata’s logs using Kibana, you’ll explore how to create and manage cases using Kibana’s timeline analysis tools.

By the end of this tutorial you will have a SIEM system that you can use to track and investigate security events across all of the servers in your network.
