Learning Outcomes
Competences
Students understand security strategies and can design and (to some extent) implement them to protect network infrastructures.
Skills Knowledge
  • Evaluate security threats and corresponding defense mechanisms for network environments based on specific use cases (K5)
  • Create and optimize a basic firewall policy (K3)
  • Set up and configure VPNs, including selecting appropriate protocols and encryption methods (K3, K5)
  • Configure security features on layer-3 switches (such as AAA, DHCP snooping) (K3)
  • Basic terminology and concepts: redundancy, automation, detection and response, defense in depth, visibility, zero trust, (micro)segmentation, SDN, SSE, SASE
  • Firewalls, VPN and remote access: firewall policies and rules, evolution of firewalls, IDS/IPS, SD-WAN, ZTNA, overview of VPN protocols
  • Securing protocols and AAA: restricting MAC-learning in switches, DHCP snooping, ARP protection, port-based authentication, protection against VLAN and STP attacks, anti-spoofing, RADIUS, 802.1X, protocols for network authentication and encryption

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 written assignments (e.g. lab reports) and written exams.
Methods The lecture combines presentations and discussions. Practical example scenarios in the network lab are used to complement and enhance the lecture content.
