Students will build up knowledge (at a different level of depth based on the topic), skills and a deep understanding of mechanisms and motivations underlying the following technologies and solutions: - Different protection mechanisms against attacks in traditional network systems and protocols; - Design common filtering solutions; - Traffic analysis to discover security problems; - Virtual Private Network and channel protection mechanisms and technologies; - Security topics in cloud computing services; - Security issues in next-generation computer networks.

Knowledge about computer networks and cloud systems as obtained in a bachelor's degree (Laurea) in computer engineering and the first module of the course "Computer networks and cloud technologies". Knowledge about fundamental aspects of cybersecurity as provided by the courses "Information System Security", such as security definitions and properties, the main category of attacks (e.g., sniffing, spoofing, DOS), basic terminology of network security (secure communication, firewall, IDS, IPS).

- Network Security Fundamentals (0.3 CFU) - Network defenses and filtering solutions: (1.5CFU) - Virtual Private Network (IPsec VPN, TLS VPN) and channel protection Technologies (1.5CFU) - Cloud Computer Security (1.5 CFU) - Security issues to Software Defined Networking and Network Functions Virtualization (0,3 CFU)

The course consists mainly of classroom lectures. These are complemented by supervised classroom exercise sessions in which students can apply the concepts learned during the lectures to realistic use cases and discuss them with the instructor. Finally, for a subset of the topics, the course includes lab sessions to help retain the concepts learned during the lectures by observing the related technologies in action. Specifically, the course is structured into lectures in the classroom for 4.8 credits and laboratories for 1.2 credits.

The teachers will provide the material (copy of slides and links to online resources) on the course website. Assessment and grading criteria for the ONSITE exam

You can take this exam before attending the course

Exam: Written test; Optional oral exam;

The exam consists of a written test that may include open-answer and closed-answer questions or exercises to check that the student has acquired the expected knowledge and skills on the Network and Cloud Security topics addressed during the course (i.e., Network Security Fundamentals, Network defenses, and filtering solutions, VPN, Cloud Computer Security, SDN and NFV security). For the part about skills, the questions may be simple exercises or use cases related to the tools experimented with in the laboratories (i.e., some questions on the topics covered in the laboratory activities may be asked). The Test is closed-book, i.e., the student cannot consult any material during the Test or use any electronic device except for the PC used for the Test. The maximum grade of the Test is 30/32, and the total duration, as measured by the Exams platform, which includes the setup time, is 1 hour and 30 minutes. A mark on the written Test greater than or equal to 25/32 will give you the right to take an integrative (and elective) oral test. In the oral test, some questions will be asked about the same topics covered by the written Text. The oral Test allows the student to obtain the 30L (i.e., 32/32). The mark can also be increased by evaluating extra activities organized in the context of the Master’s Degree course. Alternatively, the student can develop individual homework about one of the course's topics, delivering a written report followed by an oral presentation. The report and the oral presentation are evaluated up to 30L (i.e., 32/32). The final mark of the annual course "Networks & Cloud Technologies and Security" will be the average of the grade obtained for this module (“Networks & Cloud Security”) and the grade obtained in the other module (“Computer Networks and Cloud Technologies”). If the average final mark is 32, the student gets 30L. A sample exam test will be made available to the students through the Exercise platform.

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.
