Beschreibung

Introduction

This experimental project seminar is about learning and training with the advanced techniques of practical system and network security. We will have two teams (each with about 5-6 members) challenging each other and the tutoring team within three challenges - with changing roles either as attackers or defenders of a target IT system. For each challenge, the teams will have to prepare their arms: setting up a secure system (under given constraints) for the defenders, choosing and testing recon and penetration tools for the attackers. After preparation, the teams will hold a supervised Capture-the-Flag live challenge.

During the whole seminar, we will have a meta-challenge as each team has to provide the tutors a wiki, which contains all information about the team's progress.

Besides the challenges, each participant is supposed to select a security relevant topic, do research on it (reading and testing), and give a short presentation (15-20 mins) during the seminar.

Topics for the challenges:
    1. System- and Network Security
    2. Web- and Service/Application Security
    3. Managing large environments (combination of first two topics in a larger environment)

Important Notice: We are not guiding you for hacking and participation in this seminar is not an excuse for any kinds of malicious actions towards unauthorized resources over Internet!

Voraussetzungen

We are looking for good team players with strong interests in cyber security. If you got interested while seeing this page, please directly drop a line to Feng (feng.cheng"at"hpi.de) and come to the first session. Dont wait too long! First come, first served!

Lern- und Lehrformen

Students will be divided in two groups. For the first two challenges, each group is either the red (attackers) or blue (defenders) team. The blue team is preparing a network scenario for the red team.

After scenario preperation the red team is allowed to attack the scenario for several hours in a live hacking session. During this session the blue teams task is to surveil the red team. Both teams then will present their findings few days later.

During the preparation phase of the scenarios, each member of the red team will prepare one short individual introduction about attacking and defending techniques, which might get used in the scenario. The blue team has to set up the scenario itself during this time.

After the first two challenges, we will prepare a third challenge with an even more advanced scenario, covering additional topics. For documentation purposes, each team has to write a report about this challenge.

  1. Password Security and new Authentication Methods
