Cyber Defence Monitoring Course: Module 3

Module 3 of the  Cyber Defence Monitoring Course is about Large-Scale Packet Capture Analysis. It is an intensive hands-on course focusing on a single method among the diverse repertoire of Cyber Defence Monitoring techniques and solutions. The packet capture and analysis is not meant to replace IDS engines, but to be applied alongside to store and index all the network traffic and provide fast access to the captured data. In the course we use Moloch, an open-source free software tool, to build network security monitoring for different scales, from SOHO/SME up to enterprise level. CDMCS Module 3: Large-Scale Packet Capture Analysis Course

This course provides an essential tool for preparation to the Blue Teams participating at the Locked Shields exercise, as the technical environment is very complex and Blue Teams need a network traffic overview to plan their strategy. In other words, it is essential to have an overview of what happened in the network during execution. As a learning material, this course will make use of the latest Locked Shields execution network traffic capture.

Learning Objectives

The course demonstrates how Moloch is a perfect fit into modern network security monitoring. Attendees gain practical experience of how to build up a scalable system and how challenging the security-engineering and analysis process can be.

Target Audience

  • Locked Shields Blue Team members and/or national representatives.


  • Methods used to conduct network traffic analysis
  • Installing a single instance for small office network
  • Building from source to get a custom set of required features
  • Controlling a large setup
  • Using APIs for integration
  • Using proxies/aggregators to get data from external sources
  • Scaling up to 10Gb+
  • Scaling up months of history
  • Separation concerns

On this course, we will work with network traffic from the recent Locked Shields, which means that the traffic will have real intrusions.


  • Good understanding of TCP/IP networking and network/system administration
  • Recent everyday network/system administrator’s work experience, at least 2 years in UNIX environments
  • Previous detailed knowledge on following topics:
    • Work principles of UNIX operating systems and UNIX file system layout
    • Common UNIX shells (e.g., sh, bash)
    • Common UNIX user tools (e.g., ls, ps, kill)
    • Common UNIX system administration utilities
  • Scripting experience is required
  • Previous programming experience is not required, but is helpful
  • English language skill comparable to STANAG 6001,

NB! We strongly discourage the participation of students who do not fulfil any part of these prerequisites, since the course contains advanced lab sessions assuming this knowledge. The presence of unskilled attendees is likely to hinder the overall progress of the course.
