Contenus de l'unité d'enseignement

The course alternates theoretical lessons with practical ones. Three main themes  tackled during the semester are: cryptography, networking, and system security. The course is organized as follows:
Adminstrative Details
Introduction
Part 1: Cryptography

• Chapter 1: Mathematics for Cryptography
• Chapter 2: Concepts
• Chapter 3: Symmetric Cryptography
• Chapter 4: Asymmetric Cryptography
• Chapter 5: Authentication
• Chapter 6: Key Distribution

• Chapter 1: Firewalls
• Chapter 2: Proxies
• Chapter 3: Intrusion Detection Systems
• Chapter 4: Network Attacks
• Chapter 5: Spam
• Chapter 6: Virology

• Chapter 1: Passwords
• Chapter 2: Exploits
• Chapter 3: Web Security
• Chapter 4: Biometry
• Chapter 5: Access Control

Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

The objective of this course is to provide a first vision of the computer security and raise students awareness of computers security.
At the end of the course, students will be able to:

• defend needs of protection and security
• identify advantages and drawbacks, in term of security, of a computer system
• expose fundamental principles in the set-to against computer criminality
• develop a computer-based solution to a security issue

Savoirs et compétences prérequis

Each student is supposed to be able to program with a classic programming language (C - course INF0902 for CE students or course INFO2050 for CS students) and object oriented language (Java - course INFO0062).
In addition, the student must have a basic knowledge of networking (course INFO0010), operating systems (course INFO0940) and computation structures (course INFO0012).
To make easier laboratory sessions, each student should be familiar with a Unix environment (Linux, Mac OS X, Free BSD, OpenBSD).

Activités d'apprentissage prévues et méthodes d'enseignement

In addition to theoretical courses, weekly exercises lessons are organized in order to illustrate the theoretical lessons. Those lessons are organized in class, or in front of a computer in the algorithmic laboratory.
Several assignments and labs will be proposed during the semester.
The course is entirely given in English

Mode d'enseignement (présentiel ; enseignement à distance)

The course is given during the 2nd semester. Theoretical lessons are based on slides. The audience is supposed to actively participate to lessons and to take additional notes. If possible, one or several seminars will be organized, seminars in which professional in computer security will give a talk.

Lectures recommandées ou obligatoires et notes de cours

Slides are available, in printed format, at the Centrale des Cours. An electronic version (i.e., PDF) is also available on the course web page. Exercises are also available on the web page. Students are supposed to have, before each lesson, the slides and exercises.
None book is mandatory. However, for students willing to go further, those books might be a good starting point:

Modalités d'évaluation et critères

Students are graded in two ways: continuous evaluation (45% of the final grade) and oral exam (55% of the final grade).
Continuous Evaluation
During the semester, students will be evaluated several times

• Lab Reports.  A short report is expected at the end of each lab (a simple text file to fill in).  Those reports must be done individidually.  5 labs are scheduled, each of them accounting for 5% of the final grade
• Assignment 1. this is about securying a network through NATs and firewalls configuration in iptables.  This assignment must be done by teams of two and counts for 15% of the final grade.
• Assignment 2. each team (same as for Assignment 1) is required to give a 5 minute short presentation (+ 5min Q/A -- all in English) on recent information security related news published online (or in classic newspapers) after September, 18th, 2017.  The score will be given based on (1) the relevance of the news to the course; and (2) the cogency of the presentation. This assignment counts for 5% of the final grade.

• improve Assignment 1 if the grade is below 10/20.  This must be done individually.  Assigment 1 will count for 15% of the final grade.  Note that if the assignment grade during the semester was above 10/20, the grade is automatically reported in the resit.  No support (Q/A, explanations) will be provided during the summer.
• assignment 2 does count in the resit (there is no report neither improvement possible)
• lab reports are taken into account if they turn to student advantage (i.e., lab report grades > oral exam grade).
• the oral exam must be redone. It accounts either for 85% (no lab reports) or 60% (lab reports grades are integrated in the final grade)
