The teaching methodology includes: 1. Lectures to present the knowledge base that students must acquire. Students will be provided with the lecture notes used in class along with additional documents and basic text references to help in the study of the topics covered. (2 ECTS) 2. Practical lectures, where the students will have to solve exercises and quizzes. (1 ECTS) 3. Discussion of real cases to illustrate concepts and techniques introduced during the lectures. (1 ECTS) 4. Lab sessions in computer labs, where the students will learn techniques and develop skills in the use of cybersecurity tools, including binary analysis, distributed systems security and network security.
