Overall hours
Learning objectives
The purpose of the course is twofold: on the one hand, we will introduce the basic concepts on computer security, on the other hand, we will cover the security problems specific to Web and mobile systems.
Expected learning outcomes
· Being able to identify the security properties a system must ensure in order to be considered "secure"
· Knowing the main approaches that can be used to authenticate users to a machine
· Being able to analyse a security protocol and possibly highlight the vulnerabilities with respect to the most common types of attack
· Being able to identify and describe the most common attacks on Web applications
· Knowing the most frequent malware and how they propagate
· Being able to describe the security issues of mobile devices
