IT & Mobile Security

Basic Network Security

Integrated course, 5.00 ECTS


Course content

The course covers layer 1-4 of the OSI-model (Open Systems Interconnection Model) as the main topic. The focus is placed on attack vectors against computer networks and their countermeasures and mitigation strategies. In the first part of the course, the basic mechanisms (Addressing, address resolution, routing and packet filtering) of computer networks are repeated to create a common basis.
Topics: Physical Security, Layer-2 Security, VoIP-Security, WiFi Security, 802.1x, Spoofing, Denial of service attacks, trace back mechanisms and countermeasures.
Another part of the course is to work in small groups on a current topic of network security, build a practical szenario in the lab and present the results in form of a group presentation.
