Content of the Course


The "Information and Communication Security" lecture series provides a general introduction to the topic of information and communication security. Students will be qualified to identify security challenges that come along with using and employing information and communication systems, and to identify and apply adequate means and methods to solve them. Emphasis will be put on the organizational and technical set-up of infrastructures, also including aspects of pragmatic and professional risk management, and profitability analysis of security concepts and technologies. Further, students will be qualified to identify and assess security risks, in order to develop and establish appropriate security strategies. Contents presented in the lecture will also be discussed in the context of international standardization and regulation activities in the domain of information and communication security, allowing students to consider long-term developments, trends, and challenges in their analysis.
