The Advanced Cybersecurity group is focused on the methods and technologies for the protection against cyber attacks. The group is composed of teams from both universities involved in the project, namely Prof. Tanja Zseby’s team (TUW) and Dr. Jan Hajny’s team (BUT). Security of cyber-physical systems, an area where both teams are already very active, is the core of the joint research plan. In future research, WG5 will focus on particular aspects of cyber-physical security, i.e. cryptography for resource-restricted devices, machine learning for anomaly detection and side-channel attacks and stress testing of heterogeneous networks. In addition, the group will serve other working groups in their particular needs.

    Stress testing and security evaluation of network infrastructure
    The bank has updated its IT infrastructure recently, including its firewalls and network filters. The bank wanted to 1) find the true performance limits of the newly purchased security devices and 2) to verify that the devices are fully functional in case a massive attack comes.
    Solution: The high-speed traffic generator Spirent Avalanche 3100B was connected to the infrastructure of the bank. The testing device was configured to generate legitimate traffic (HTTP(S) requests) and analyze the behavior of the infrastructure. The load was gradually increased from Kbps to Gbps. Malicious traffic, namely various DDoS attacks, were mixed into the legitimate traffic to evaluate the operability of network filters. The complete test was running in a live infrastructure and network administrators had the right to stop the test immediately.
    Results: The performance limits of the firewalls and network filters were found. The behavior of the infrastructure under extreme load was analyzed. The functionality of security devices was evaluated and devices not performing as promised by vendors were identified. The main bottleneck of the infrastructure (a particul

  • Spirent Avalanche 3100B
    Device capable of performance and security testing of network infrastructures and services. Extreme traffic of up to 20 Gbps can be generated by the device to evaluate the scalability and behavior of the infrastructure or service in non-standard conditions.
  • Vulnerability Scanners
    Wide spectrum of vulnerability scanners is available. The scanners are able to analyze the customer’s network and find the security weaknesses, including misconfigurations, old versions of software or weak protection. Using the analysis results, the security team provides the remedy for the customer.
  • Data Storage and Computing Cluster
    The TUW network security lab contains a data storage and a computing cluster for network traffic analysis and anomaly detection methods. The infrastructure will also be used to collect and analyze sensor data from the microgrid lab (FUSE testbed) that is currently established at TU Wien.
