Network Packet Analysis (NPA)

Google Review

 The Network Packet Analysis (NPA) course starts with the fundamental networking basic concepts, networking methodologies. This course will drive you into necessary software tools to analyze network data packet traffic for the purpose of intrusion and threat detection, network defense and primarily to identify offensive operations by attackers.

NPA is an outstanding industry standard training program for participant who are interested in analyzing traffic to learn how a program or application works using network, or determining if a networked device is infected with malware or intruders. If you perform incident response or are involved with investigations, this course will help you take your skills to the next level. Wireshark will be used as the primary analysis tool.

Wireshark® is an open source Network Packet Analyzer for analyzing the TCP/IP communications. The participants will experience the use of Wireshark to identify problems in TCP/IP communications. At the end of the workshop, all the participants will have practical knowledge of how to use Wireshark efficiently to analyze and trouble shoot network performance problems.

Benefits of NPA

  • What is Live network traffic, the need for its analysis.
  • Capture packets on wired networks.
  • Use time values to identify network performance problems.
  • Filter out traffic for more efficient troubleshooting and analysis.
  • Implement Wireshark coloring rules to focus on network problems faster.
  • Live demonstration on how attacks, vulnerabilities and defensive method can be done Network layer to Application layer.
  • Use Wireshark's Expert System to understand various traffic problems.
  • Use the TCP/IP Resolution Flowchart to identify possible communication faults.
  • Analyze usual/unusual Domain Name System (DNS) traffic
  • Analyze usual/unusual Address Resolution Protocol (ARP) traffic
  • Analyze usual/unusual Internet Protocol v4 (IPv4) traffic.
  • Analyze usual/unusual Internet Control Messaging Protocol (ICMP) traffic
  • Analyze usual/unusual User Datagram Protocol (UDP) traffic
  • Analyze usual/unusual Transmission Control Protocol (TCP) traffic
  • Analyze usual/unusual Hypertext Transport Protocol (HTTP/HTTPS) traffic

Learn With Fun


infySEC IS Lab is an extreme Online Virtual Remote Lab provided to participants where they can work from any place at any point of time without restriction. ISLab provides login privilege to Network Packet Analysis participants where they can work in our Virtual Remote Server and start doing their Labs.

Our ISLab was created in such a concept called “Learn with Fun” where each participant will face gaming-like structured online hacking program called 'Live Hacking Zone' which contains many Levels relevant to the topics covered on the program. Each participant has to cross levels to face NPA exam, Hence NPA will only deliver equipped candidates. Participant have to cross multiple Levels starting with easy to toughest level. Each participant can track other participants activity live which helps each participants to get involved into Live Hacking Zone competition, Prepare to be SHOCKED, ENTERTAINED and EDUCATED all at the same time.
