1:51 Title of the lecture: Deep Packet Inspection Analysis: Examining One Packet Killers.
2:30 Description of the lecture: 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.
