Objectives Students understand the basic security functionality and tasks of various network (security) devices. They can estimate the trade-off between effort, cost, and usability that is required to achieve a certain security level.
Subject Security considerations in LANs (e.g. restricting MAC-learning in switches, DHCP snooping, ARP protection, port-based authentication, protection against malicious devices like rogue routers, possible attacks against RSTP/MSTP/PVSTP, protection against VLAN hopping), Anti-Spoofing in routing devices, Firewalls (incl. DPI), network based IDS/IPS (Intrusion Detection and Prevention Systems), VPNs (Virtual Private Networks), AAA (e.g. RADIUS).

These topics are presented as an overview; a selected set of concepts is discussed in greater detail and is also practiced in hands-on labs.

Criteria for evaluation Grading is based on class participation in lab exercises, written summaries of the lab exercises and a final written examination. To pass the course, students must successfully pass all three sections.
Methods Lecture includes discussions and small presentations. Practical example scenarios in the network lab complement and extend the lecture.
