SASC01 An Introduction to Information Security, 7.5 credits

Information must be protected for several reasons. Some information must be protected from eavesdroppers and some from unauthorized modification. Users must be authenticated and access to information must be controlled. At the same time, the number of Internet connected devices are increasing and so is the amount of information that we are able to access online. This course will give an introduction to the problems we are facing when designing security for computers, mobile devices and web applications. It will also give an overview of the solutions to these problems. The course focus will be on concepts and ideas, not on technical details. Still, the goal is to provide a good understanding of building blocks, attacks, and defenses. It is suitable for anyone that wants to have an increased general understanding of information security and how it affects the systems and products that we interact with in everyday life.
