Ce projet consiste à créer de toutes pièces un shell complet, en reprenant le travail effectué sur votre 21sh. Un jeu minimum de fonctionnalités vous sont demandées, à partir duquel vous allez constuire votre propre shell abouti - en allant potentiellement jusqu'au job control et au shell script. Ce projet vous permet donc de voir ou revoir une très large palette des fonctionnalités UNIX (et POSIX) standard.

Introductory project to computer security in the specific field of the web, this project has you audit a deliberately vulnerable web platform. You will exploit real-world vulnerabilities to escalate your access from an anonymous visitor all the way up to administrator, capture the flags hidden along the way, and understand how each breach could have been prevented, both from a programming and a design perspective.

The aim of this project is to become familiar with assembly language.

This subject follows Init where you have learn some of basics commands and first reflexes in system and network administration. This one will be a concrete example of the use of those commands and will let you start your own first web server.

Eleven independent security challenges on a deliberately vulnerable Linux VM. Each level requires a distinct technique: binary analysis, process and filesystem inspection, code injection through configuration files and templates, protocol reverse engineering, jail escapes, and side-channel attacks. You will learn to read and exploit systems you did not write, using the tools and mindset of a security researcher.
