Topic: Deep Packet Inspection Analysis: Examining One Packet Killers


Abstract: Security Operations Center (SOC) teams monitor network traffic using SIEM and IPS solutions, along with other security tools. However, these tools can sometimes fall short in their capability, particularly when faced with complex attacks that exploit legitimate network protocols, such as a single, crafted packet. To combat these threats, SOC teams must adopt advanced techniques such as Deep Packet Inspection (DPI). The webinar explores DPI analysis techniques to detect and mitigate “One Packet Killers,” using real-world examples from DHCP, H.225.0, Modbus over TCP, WTP, and BAT_GW protocols. Furthermore, it examines the intricacies of each protocol and highlights how specific message manipulations within these protocols can activate Denial-of-Service (DoS) attacks or disrupt communication flows. By mastering DPI techniques and addressing these protocol security weaknesses, SOC teams can enhance their ability to maintain a robust network security posture.
Key Takeaways: 

  • Understand how attackers exploit protocols with single packets and the limitations of IPS, WAF, and SIEM in detecting them.
  • Learn about “One Packet Killers” and how they bypass traditional security measures.
  • Grasp the importance of DPI analysis in identifying “One Packet Killers.”
  • Analyze “One Packet Killers” using examples from DHCP, H.225.0, Modbus/TCP, WTP, and BAT_GW.
  • Implement monitoring techniques and learn mitigation strategies using DPI and protocol-specific anomaly detection.
