Learning objectives
The objective of the course is to present, in a critical perspective, the basic principles on computer security and to analyze the threats to systems in TCP/IP networks and possible countermeasures. To this purpose, the course will focus on the most important approaches for the definition of security policies, and on the most diffused attacks to network protocols and related infrastructures.
Expected learning outcomes
At the end of the course, the student will know common threats both in local networks and in the infrastructure and will be able to: discuss and design security in complex networked systems; analyze TCP/IP protocols from a security perspective; analyze traffic to discover security problems; build common network defences such as firewalls and network intrusion detection systems; defend user security in untrusted networks.

Assessment methods and Criteria
The exam consists of a mandatory written test with open answers including a test in laboratory. At the end of the test, the evaluation is expressed on a scale from 0 to 30, taking into account the following parameters: grade of knowledge on the topics, capacity of applying the knowledge to real problems. An optional oral discussion on a topic or on the description of a project can be requested to increase the final evaluation.
