Security in IP Networks

Recognizing and Closing Security Gaps

Recent years have given rise to an abundance of new methods of attack. The providers of protective measures, however, have not been idle, either. As a result, the topic of network security has become increasingly complex compared to earlier days. The know-how imparted in this course is the basis for taking over tasks in security planning and administration of IP-based networks, which the participants will be able to perform on their own account.
