Introduction
Security is widely recognized as being of great importance in all areas of information technology: networks, operating systems, databases etc. Security is about regulating access to assets. Crucial questions are: Who are you? and: Should you be doing that? Authentication (of people and computers) and access control are basic aspects of computer security. Cryptography provides a mathematical toolset for realising key security goals, via appropriate protocols. This bachelor lecture introduces the basics of computer security, both for computer science and information science students.

Objectives
At the end of this course: - You are able to recognise -- in society in general and within a job environment in particular -- situations in which information security plays a role.
- You are able to recognise relevant security goals in such situations (confidentiality, integrity, availability, authenticity, non-repudiation, accountability).
- You can (on a global level) describe basic techniques to achieve these security goals, evaluate existing solutions, and propose new solutions in practical situations.
- You recognise the social and organisational implications of security technologies (especially privacy), and you can take these aspects into account in your analysis of practical situations.

Teaching methods
The course consists of weekly lectures and exercises. The exercises are compulsory, and make up half of your final mark.Exercises may be done in pairs. Your solution has to be handed in on paper before the deadline, at in the mailbox of your exercise course teacher on the 2nd floor of the Huygens building. Exercises not handed in in time will be graded 1; submission by e-mail or Blackboard is not accepted. Copying or stealing work from others or from the Web will result in all involved parties failing the course and notification of the exam committee, so make sure we don't discover anything if you copy yourself, and secure your own work against copying by others.
