Overview What You Will Learn Curriculum Instructor

Course Overview

Networking is at the core of every modern enterprise whether on-premise or in the cloud. Locating intrusions and threats “on the wire” is an essential practice to every security program. A critical tool for scalable monitoring of hundreds and thousands of hosts is the intrusion detection system (IDS). Implementing solutions, such as Suricata as an IDS or inline as an intrusion prevention system (IPS) will help scale your security monitoring and response capabilities across vast networks regardless of the architecture. 

There are many tutorials, training, and documentation that describe the installation and basic usage of Suricata but don’t prepare security engineers and analysts to optimize the implementation with end-to-end lifecycle considerations on how to customize detections using Suricata and make robust detection use cases. Considerations for architectural planning, performance tuning, detection language syntax, and rule testing are also an important part of your success in the care and feeding of your detection engineering program. With hands-on guidance and modern detection implementations, Suricata can be a performant and affordable network IDS solution for many enterprises. 

This course will take you through architectural considerations, how the Suricata engine works, creating custom detections, and how to test those detections successfully for scalable utilization. 

What You Will Learn

  • Understand deep level packet analytics and how network intrusion engines parse the data.
  • Apply PCAP analytics to writing tcpdump and wireshark filters for sizing and tuning of IDS engines.
  • Forensically carve files and indicators from PCAP streams for extended analysis in tools outside of Suricata.
  • Create custom detection use cases for Suricata and generate offensive payload for testing.
  • Develop GitHub based CI/CD runner scripts to automatically test and deploy your custom detections to Suricata.
  • Deploy Suricata as a monitoring IDS using Ubuntu VM and inline using PFsense VM and develop custom scripts for active response techniques.
  • Adapt packet filtering and analysis skills from Wireshark to Cloudflare WAF rules.
