About the Job

Requirements

  • Be a final-year engineering-school student seeking a graduation internship.
  • Have a specialization in networks and security, cybersecurity, or embedded systems/Internet of Things security.
  • Have solid knowledge of 4G/5G mobile networks and cybersecurity for distributed systems.
  • Have practical proficiency with Python, C/C++, Scapy, Burp Suite, and embedded platforms such as Raspberry Pi or Jetson Nano.
  • Have knowledge of network communications analysis and security, including Wireshark, Nmap, Transport Layer Security, and virtual private networks.
  • Have knowledge of intrusion and anomaly detection using Snort, Suricata, and Zeek.
  • Have knowledge of systems monitoring using ELK, Grafana, and Prometheus.

Responsibilities

  • Detect security flaws with 5Ghoul on the 5G testbed to identify hardware and software vulnerabilities in modems and protocols.
  • Analyze radio vulnerabilities on the 5G testbed by testing targeted jamming of PSS/SSS channels, base-station spoofing through SIB1 spoofing, and Timing Advance manipulation to desynchronize user equipment.
  • Use Sni5Gect to inject malicious messages into the testbed and observe their impacts.
  • Deploy countermeasures on the 5G testbed, including RACH/SIB1 message encryption, rogue gNB detection through behavioral analysis, and anti-jamming mechanisms such as frequency hopping and channel redundancy.
  • Integrate 5G testbed logs into a security information and event management system to centralize monitoring, detect anomalies such as RRC storms and abnormal Timing Advance values, and correlate events with other data sources.
  • Validate resilience by measuring defense effectiveness through concrete tests on the USRP, including downgrade blocking and abnormal Timing Advance detection.
  • Propose improvements based on test results, such as strict validation rules for critical parameters including Timing Advance and Tracking Area Code, and optimization of early encryption mechanisms.
