The course is structured into lectures in the classroom (4.5 credits) and laboratories (1.5 credits), consisting of using software tools and sniffers to practice some of the theoretical attacks seen during the classes. During the labs, the students will discuss their solutions to the assigned exercises with the teachers. Students will work in groups and prepare reports on lab experiences. Students will grade other students’ reports using a peer grading platform. During the labs, students will participate in challenges to complete attacks seen during the course.

The teachers will provide the material (slides and links to online resources) on the course website.

Exam: Optional oral exam; Group essay; Computer-based written test in class using POLITO platform;

Exam: Optional reports (1 point each): Students will work in groups and prepare two reports. Students will grade reports of other groups via the peer-grading platform. For each report, the top 80% of reports will obtain 1 extra point, while the bottom 20% will get 0.5 points. Students participating in the peer grading will get 1 point if their review is thorough and properly done, 0.5 if superficial, and 0 if not done or inconsistent. Challenges (1 point each): during the labs, students will have to demonstrate their abilities to mount attacks seen during the course. Students completing the challenge within a deadline will get one extra point. Interaction during classes (1 point max): students answering questions during classes will get one extra point. Computer-based written test in class using the POLITO platform (28 points max): The exam consists of a written test that includes open-answer and closed-answer questions or exercises to check that the student has acquired the expected knowledge and skills (see expected learning outcomes). For the part about skills, the questions may be simple exercises or use cases related to the tools experimented in the laboratories. For each question, the maximum grade that can be obtained is specified. The final grade will be the sum of the grades assigned to the answers given to the questions. The written test will be taken in a classroom using the Exams platform. In case of technical problems, the students may be asked to write their test with pencil and paper. The total duration of the test, as measured by the Exams platform, which includes the setup time, is 1 hour and 40 minutes. The test is closed-book, i.e., the student cannot consult any material during the test and cannot use any electronic device except the PC used for the test. A set of sample questions is available to the students through the online course platform. Optional oral test: The teacher may request an oral test to be carried out in case of doubts about the evaluation of the written test. The oral test will consist of additional questions to resolve the teachers' doubts that emerged in evaluating the student's written test. Final grading: the final grade will be the sum of the written exam (max 28 points), the group reports (max 2 points), the peer grading participation (max 2 points), the challenges (max 1 point) and the class interaction (max 1 point).

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
