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 5: Spam
  • Chapter 6: Virology
Part 3: System Security
  • Chapter 1: Passwords
  • Chapter 2: Exploits
  • Chapter 3: Web Security
  • Chapter 4: Biometry
  • Chapter 5: Access Control
Learning outcomes of the learning unit :
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
In addition, each student will develop several practical skills related to computer security. Each student will be able to use cryptographic Java libraries. Further, he will be able to set up firewall and NAT policies through iptables. Finally, any student will have the opportunity to improve his English skills.
Prerequisite knowledge and skills :
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).
Planned learning activities and teaching methods :
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 of delivery (face-to-face ; distance-learning) :
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.
Recommended or required readings :
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:

Assessment methods and criteria :
Students are graded in two ways: continuous evaluation (55% of the final grade) and oral exam (45% of the final grade).
Continuous Evaluation
During the semester, students will be evaluated several times
  • Written Test.  It will be based on paper exercices about the Cryptography part of the course.  The written test lasts 2 hours and counts for 15% of the final grade.
  • Lab Report 1.  A short report is expected at the end of the lab on Exploit (a simple text file to fill in).  This report must be done individidually.  The report counts for 5% of the final grade.
  • Lab Report 2.  A short report is expected at the end of the lab on Web attacks (a simple text file to fill in).  This report must be done individually .  It counts 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.
Those continuous evaluations are all mandatory in order to access the oral exam.  In case of missing one (or more) of them, the student will not be allowed to present the exam and will get an absence grade.
Oral Exam
It is about the theoretical part of the course. Any student randomly selects one question and prepares its answer on the board. It counts for 45% of the final grade.
Resit
In case of failure in June, a student must:
  • 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)
  • the oral exam must be redone.  Note that, in case of failue to the written test and/or Lab 1 and/or Lab 2 reports, the student may also have a "practical question" (e.g., RSA calculation, Chinese Remainder Theorem, etc.).  The oral exam, during the resit, counts for 85% of the final grade.
