Learning unit contents

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).

Learning outcomes of the learning unit

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.

Prerequisite knowledge and skills

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

Planned learning activities and teaching methods

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).
  • Assignments in teams of 2 students. 

Mode of delivery (face-to-face ; distance-learning)

The face-to-face lectures are complemented by lab sessions and assignments (carried out remotely).
The course is entirely given in English.

Slides, as well as assignments and labs subjects, are available on the course Web Site.

Assessment methods and criteria

The evaluation is threefold:

  • Labs are evaluated (a simple text file to fill in during/right after the lab with students' answers).  They account for 25% of the final grade.
  • Assignments account for 25% of the final grade.
  • The oral exam (on the theoretical part of the course) accounts for 50% of the final grade.  Note that the oral exam will require the student to answer to 2 questions (one based on material reviewed by L. Mathy, the other 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 and/or assignment not provided, the student will receive an "Absence" grade (and automatically be postponed to the resit).

In case of failure in June, students must improve their assignment for the resit (deadline: 1st day of the resit session) if the grade was below 10/20.  This must be done individually (note that no support will be provided, either by the TA or the lecturers, during summer).  Labs cannot be redone.     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 a project and the oral exam the following year.

Organizational remarks

The course is proposed every 2 years (given during Academic Year 2018-2019).
The course is given during the second semester
