Network Security

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.

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.
