Practical IT-Security

SM 450

During this seminar different security topics will be dealt with. In particular, current research results from the following areas are in the foreground: Internet of Things Security, Web Security, Mobile Security, Biometric Security, Cloud Security, Automotive Security, Malware, Crypto & Politics, but also classic areas such as Hardware Security, System Security, Digital Currencies and Cryptography. The main aim is to understand and present the work and also to present concrete implementations or experiments.

In the context of this seminar each participant has to scientifically work on a topic and give a presentation about it. Furthermore, a handout must be handed out to accompany the lecture. Finally an active participation in the lectures of the other seminar participants is desired.

  • Intention

    The intention of this seminar is to provide you with a platform where you can practice preparing and giving presentations. While classical lectures focus on the teaching of materials and methods and their application, there are hardly any situations in your studies where you can learn how to give lectures.

    The offered seminar should fill this gap partially. In this respect, the main focus of our seminar is not on the creation of seminar papers, which is partly redundant for the creation of final papers, but on the presentation itself. The lectures therefore last one hour, while the rest of the time is used for discussion and feedback. As a consequence, the grading is primarily based on the lecture.

  • Evaluation

    Talk: A talk lasts exactly 60 minutes.

    Handout: The handout should be concise and informative; no longer than 6 pages.

    Longer talks: If you anticipate to need more than 60 minutes, e.g. for demonstrations, talk with us and we can probably accomodate that.

    Early feedback: If you would like to receive feedback on your presentation before your talk, please send us your slides by e-mail no later than one week before your presentation date.

    Submission: You must submit the slides of your presentation and your handout (PDF, alternatively PowerPoint and Word) no later than the day of your presentation, before your talk. Please send both, the slides and the handout, to us by e-mail.

    Grading: The focus of the seminar is on the induction and presentation of the given topic/material. This includes content as well as form and presentation style as well as the handout. The final grade is calculated as follows:

    • Talk: 80 %
    • Handout: 20 %
