Contenus de l'unité d'enseignement

On one hand, a Digital evidence refers to any probative information stored or transmitted in digital form that a party to a court case may use at trial (e.g., emails, digital photos, ATM transaction logs, databases backups, ...).  On the other hand, digital forensics is a branch of forensic science concerned with the proper acquisition, preservation, and analysis of digital evidence, typically after an unauthorized access or use has taken place.  Digital forensics follows the goal to explain the current state of a digital artifact.

This course aims at providing a first look at digital forensics, in particular focusing on network forensics (i.e., monitoring and analyzing network traffic), computer data forensics (i.e., flash, HDD, USB device), and mobile devices forensics (i.e., collect digital evidence from mobile devices).

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

Upon completing this course, students are expected to:

  • understand the basics of computer data and network forensics
  • acquire hands-on practice on digital forensics investigation
  • be prepared for active research at the forefront of this area.
Ce cours contribue aux acquis d'apprentissage I.2, II.2, III.1, III.4, IV.3, IV.4,
VI.1, VII.1, VII.6 du programme d'ingénieur civil en informatique.  

Savoirs et compétences prérequis

Students are supposed to have a good knowledge of basic Computer Networking (INFO0010 or assimilated) and of basic Operating Systems (INFO0940 or assimilated).
It is not required to have any knowledge in Computer Security

Activités d'apprentissage prévues et méthodes d'enseignement

The course is organized as follows

  • Lectures (30hours) describing in details the theoretical and practical aspects of the course
  • Lab sessions (10h) to be done individually.  Each lab ends with a small report to complete (a simple text file to fill in with answers or pieces of code).

Mode d'enseignement (présentiel, à distance, hybride)

If possible, face-to-face lectures will be organized, in addition to lab sessions and assignments (carried out remotely).
According the CoVID19 pandemia evolution, it is still possible that the course will be reorganized remotely (WebEx/Collaborate virtual classes, podcast, ...)
The course is entirely given in English.

Modalités d'évaluation et critères

Examen(s) en session

Toutes sessions confondues

- En présentiel

évaluation orale

Evaluation continue


Explications complémentaires:

The evaluation is twofold:

  • Labs are evaluated (a simple text file to fill in during/right after the lab with students' answers).  They account for 40% of the final grade.
  • The oral exam (on the theoretical part of the course) accounts for 60% of the final grade.  Note that the oral exam will require the student to answer to only one question (based either on material reviewed by L. Mathy, or by B. Donnet).
Presence at labs is mandatory. Attending all labs and doing both assignments are required for attending the oral exam.  In case of Lab absence, the student will receive an "Absence" grade (and automatically be postponed to the resit).

In case of failure in June,  if the grade of the labs is favorable to the students, the resit session is identical to the first one, with the same weighting. On the other hand, if the grade of the labs is not favorable to the student, it will not be taken into account in the weighting in September.  Oral exam must be redone.

As the course is given every two years, in case of (definitive) failure, the student will have to do  the oral exam the following year.
