Selected Topics in IT-Security
CS 408 | English
Lecturer: Prof. Dr. Frederik Armknecht
Teaching Assistants: Christian Müller and Jochen Schäfer
The large-scale deployment of Internet-based services and the open nature of the Internet come alongside with the increase of security threats against existing services. As the size of the global network grows, the incentives of attackers to abuse the operation of online applications also increase and their advantage in mounting successful attacks becomes considerable.
These cyber-attacks often target the resources, availability, and operation of online services. In the recent years, a considerable number of online services such as Amazon, CNN, eBay, and Yahoo were hit by online attacks; the losses in revenues of Amazon and Yahoo were almost 1.1 million US dollars. With an increasing number of services relying on online resources, security becomes an essential component of every system.
This course aims to increase the security awareness of students and offers them a basic understanding with respect to a variety of interesting topics. After this course, students will be able to (1) learn about symmetric and asymmetric encryption schemes, (2) classify and describe vulnerabilities and protection mechanisms of popular network protocols, web protocols, and software systems (3) analyze / reason about basic protection mechanisms for modern OSs, software and hardware systems.
