Who Should Attend?

The workshop is intended for IT systems administrators and IT security incident responders.

Course Content

The aim of the exercise is to develop proper habits and practice in handling incidents defending against attacks targeting IT infrastructure. Participants will be given an existing infrastructure containing a web server, mail server, file server, DNS server, etc., which they must defend using various defense techniques. They will be required to properly protect infrastructure, detect attacks, and make rapid decisions related to the current threat. The participants' group-work and problem-solving abilities will also be evaluated. The teams will be evaluated throughout the exercise in order to assess the effectiveness of each action. The exercise ends with presentation of team results and additional discussion.

This exercise consists of group of challenges. In each challenge participants have to solve a problem, analyse code/data or find information. After completing each challenge, participants answer control questions or find hidden flags. Various tasks require different sets of skills to complete – network analysis skills, information gathering, data/log analysis, and/or reverse engineering. Not all challenges will be available from the start. The challenges focus on attacks on a telecom operator, a bank or financial institution (the company) and its clients. The exercise aims to test cybersecurity teams: how they are capable of dealing with real-life attacks and scenarios. To complete some of the challenges, malware analysis labs are necessary (one challenge involves analysis of a real malware sample). There will be six challenges, but information about them should NOT be disclosed to the participants -- it is available on request for organisers.

Participants in the exercises are requested to prepare a computer environment in which they will be able to analyse malware designed for Windows OS (preferably in an isolated, secure environment, e.g. virtual machines). There must be at least one environment for each exercise group. We also recommend participants have Linux OS for other types of analysis. We recommend using the following ENISA exercise to prepare the environment:
