Security Circus
Feynman’s Maxim: An organization will fear and despise loyal vulnerability assessors and others who point out vulnerabilities or suggest security changes more than malicious adversaries.
— Richard Feynman

Course Overview

Computer security incidents happen every day in small or large private or public organizations but also computer equipments used by citizen world wide. In case of incident, victims want to know what exactly happen to their systems, information to understand the impact on their organization or/and on their life. Security researchers need to analyse such compromised systems to better understand techniques, tactics and motivation of the attackers/adversaries.

The aim of the course is to provide a basic ground of all the techniques used in computer forensic and offer a toolbox to the student for their future activities in the computer security field.

The course includes a project to support or perform computer forensic to turn the theory into a practical session. The course requires a high involvement from the participants.

Student will get access to real malicious data and information but also personal identifiable information (PII). A high level of ethic is required during his/her participation.

Project Detail

During the period of the course, there will be a specific project to realize. The project is fully integrated into the course sessions that means some topics covered will help to enhance or complete your work.

Project definition should be known for the 2014-12-05.

A project can be:

  • A free software tool or extension to support forensic investigation

  • A detailed and exhaustive analysis of computer evidences found in the wild

Project will be released under a free software license and using one of the following programming language: Python, Perl, Ruby, Go, Lua, Bash or Zsh. As the development of the project will be done on an operational system, the project along with its tools might evolve following the feedback received from the attackers themselves. The project can be an improvement to an existing free software security project including extensions, documentation, improvements or even bug fixes to computer forensic software. If you don’t have any ideas, I’m sure we can find something in a world surrounded by information security issues, insecure technologies and potential innovative technical solutions (also sometime insecure).

A project can be also an analysis of specific evidences collected in the field (e.g. malware discovered, malicious website, hard-disks found in a recycling center) where you explain what you did as a forensic investigator.

Operational Aspect

The system to be used for the project is shared among the class including the system administration of the system. Security and system administration is part of the overall project. This includes adequate system administration, OpenSSH key management, logging management and security monitoring on wild Internet. Git will be extensively used during the courses.

You must also create a GitHub account where all your project including its documentation will be available (publicly).

Workstation Requirements During Classes

The major part of the work during the classes is a mixture of practical exercises, real-life experiments and sometime a kind of theory. The main requirement is that your workstation is an operational Unix-based system (e.g. a recent GNU/Linux distribution like Ubuntu 14.xx or a BSD flavor like OpenBSD or FreeBSD) with system administrator privileges.


Courses will be given in French with the technical support being in English. Your project will be in English as your code and documentation will be available to the Internet community at large.


The evaluation will be mainly based on your project. The evaluation is not an objective and the objective is to have fun while learning all together.


You may find that the subject very broad or even too complex. The objective is that you keep a focus on a specific aspect of computer forensic (network, system, malware analysis, data mining) to be used for your project. If you have any issue with the course (including the way I teach it), don’t hesitate to talk about as early as possible.
