  • Research on WinPcap Capture IPv6 Packet Method
    2013 International Conference on Computer Sciences and Applications, 2013
    Co-Authors: Zhenqi Wang, Dankai Zhang
    Abstract:

    Introduction, description the structure and implementation process for WinPcap, then analyzed differences between IPv4 and IPv6 Packet header, finally proposed a method to improve the efficiency of capturing Packets. Using VC + + 6.0 program experiment implemented IPv6 Packets Capture and verify that the improved method is efficiency than the traditional method on Capture Packet.

  • Performance Analysis of Packet Sniffing Techniques Applied to Network Monitoring
    IEEE Latin America Transactions, 2020
    Co-Authors: Pelayo Nuño, David Martinez Alvarez, Francisco Ballestín González, Juan C. Granda
    Abstract:

    Network monitoring based on Packet sniffing is one of the most useful techniques applied by system administrators and security analysts in order to identify threats within a local network. Despite being supposedly a simple task, it could sometimes be a highly resource consuming process. In this paper, the use of two sniffing techniques, scapy and raw sockets, to achieve better performance in terms of maximum Capture Packet rate are analyzed and compared. Furthermore, both techniques are optimized by using BSD Packet Filtering to improve Packet Capture, and a multicore architecture in order to reduce the exposition to denegation of service attacks. Finally, a system based on those techniques that is able to automatically detect layers 2 and 3 common vulnerabilities and attacks within the scope of corporative networks is developed. The result is an enhanced system focused on link and network layers that can be deployed in corporative environments regardless of its size.

  • Embedded Packet Logger for Network Monitoring System
    Lecture Notes in Electrical Engineering, 2015
    Co-Authors: Chanankorn Jandaeng
    Abstract:

    The network monitoring system (NMS) consist of three parts: data collection, data analysis and visualisation. The sensor agent is implemented on managed device and server in order to send traffic, audit log and network information for analysis. On the other hand, the unmanaged device does not have software to support the management function. Moreover, the end user or client behind L2-switch should be monitored by NMS. This paper implements embedded Packet logger (EPL) for Packet sniffer in switch rack. As the small switch rack is distributed in campus building, it hards to monitor and support in order to keep it safety. The embedded system can eliminate this problem. The EPL, light weight package sniffer, is implemented and embedded in RaspberryPi board, these hardware installed Linux kernel. We compare the traffic measurement and resource consumption with tcpdump(1), the EPL efficiently Capture Packet like tcpdump(1). Moreover, the memory and CPU consumption do not different significantly, with lower storage space than tcpdump(1).
