Syllabus
Prerequisites: Students should be familiar with the fundamentals of programming (as given in the introductory "Programming" course). Basic knowledge of operating systems as provided by the course "Operating Systems" is also helpful.
Target skills and knowledge: The main objective of this course is to provide an all-around panoramics of the basic notions that build up the big world of networks, trying not only to understand how it works, but above all why it works this way. We will therefore analyze all the various fundamental layers, starting with the physical layer and going up to the above layers (data link, medium accesso control, network, transport, application). We will then go on with the topic of network security, showing the fundamental concepts and technologies.
Examination methods: Each student must pass a written examination. Above a certain minimum eveluation threshold, each student can optionally request an additional oral examination.
Assessment criteria: The main evaluation criterion is the comprehension of the network and security technologies show during the course. This means being able to know how a technology works, its pro's and con's, its interaction in the overall context.
Course unit contents: + Introduction to networks
Network categorisations and classifications, reference models.

+ The physical layer
Properties of the communication media, from the wired to the wireless to satellites.

+ The data link layer
Framing, error-detection and error-correction techniques, flow control.

+ The medium access sublayer
Multiple access protocols, ethernet, wireless technologies.

+ The network layer
Connection types, routing, quality of service, internet.

+ The application layer
Transport protocols, internet.

+ The transport layer
The Domain Name System

+ Security
Vulnerabilities, cryptography, symmetric and public keys, digital signatures, communication and application security, authentication.
Planned learning activities and teaching methods: The course is mainly constituted by class lessons, with a final part in lab showcasing practical methodologies in security.
Additional notes about suggested reading: The material necessary for the exam is mainly provided by the reference textbook, with integrations provided with online material.
