Information Security (IN0693)
University of Udine - Scientific Pole
The course is provided in blended e-learning mode using the Moodle platform of the University of Udine and the whole teaching material will be available on-line. Teaching methods include lectures, flipped classroom, classroom exercises, and laboratory activities.
The course aims at providing students with the knowledge and methods to deal with the analysis, design, and implementation of secure systems in different application contexts. First, students learn the security fundamentals, such as security services and mechanisms, threats and vulnerabilities, attacks, defenses, security models, etc. Various mechanisms for the implementation of effective defense services will then be investigated, analysing both the theoretical and practical aspects and finally introducing some advanced topics in the field of information security. The course is accompanied by numerous practical examples and exercises as well as laboratory experiences and hands-on projects.
The exam is distributed over two separate days and it comprises a written test and an oral test in addition to the development of a laboratory activity assigned during the course. The written examination is devoted to assessing both the student's knowledge and understanding of theory and methods related to the topics covered in the course, as well as the student's ability to apply this knowledge to solve real‐world problems. The oral interview plus the evaluation of the laboratory activity report will take place after passing the written test.
