Module authority:	Prof. Dr. Frank Kargl
Lecturer:	Prof. Dr. Frank Kargl
Language:	english
Turn / Duration:	every summer term / 1
Requirements (contentual):	Foundations of Computer Networks and Operations Systems
Requirements (formal):
Basis for:	Specialized lectures like PETs, SPMS, PSEC, and others.
Learning objectives:	The students know the basic security problems, requirements and mechanisms in IT systems. They are able to evaluate the security of IT systems at different levels. They are able to identify and analyze vulnerabilities and understand described attack mechanisms. In addition, students are able to discuss possible solutions and secure systems appropriately. To a limited extent, students have also gained experience with the use of concrete security tools and mechanisms.
Content:	The course offers a broad introduction to the topic of IT security. After a short introduction to the basics of IT security and cryptography, topics such as identification and authentication, access control mechanisms, software and host security, internet and web security, embedded and hardware security, data protection and privacy are presented. The focus is to provide a broad overview, which can later be deepened in specialized courses - e.g. on security and privacy in mobile systems. The course also presents selected current research topics in IT security.

Grading procedure:	The module examination consists of a graded written examination. If a specified academic work is achieved, a grade bonus is awarded in accordance with §17 (3a) of the General Examination Regulations at the immediately following examination. The examination grade is improved by one grade level, but not better than 1.0. An improvement from 5.0 to 4.0 is not possible.
