Course Description

Industry expert Dr. Avril Salter teaches this 4-day instructor-led Wireshark Training course. You’ll learn how to use Wireshark to understand common network security protocols that are deployed in IP networks today, including:

  • Telnet & SSH
  • TLS both the legacy versions & the new version 1.3
  • Key IPsec protocols, which includes IKE, ISAKMP, AH, & ESP
  • 802.1X port-based access control, which encompasses RADIUS, EAP & EAPoL

Network security protocols are designed to ensure the privacy and integrity of data that is transitioning our networks and prevent unauthorized access. They define the processes and message exchanges to protect networks from illegitimate attempts to capture and extract meaningful information about the network or the data carried over the network.

In this Wireshark training course, you’ll capture traffic and identify the security protocols implemented in today’s enterprise networks. This is a deep dive analysis of network security protocols. You will also understand key capabilities in Wireshark that can be used to analyze and troubleshoot network traffic to identify security issues, including:

  • Defining Wireshark security profiles
  • Using Wireshark capture and display filters to identify protected and unprotected traffic
  • Coloring rules
  • Using relevant Wireshark statistical tools
  • Leveraging Wireshark decryption capabilities

Instructor and author Dr. Avril Salter, CCNP-W, CCNA-S, has extensive experience in packet-level network security analysis and frequently lectures on this topic. She is a guest instructor at numerous telecommunications and network companies, teaching their internal staff to perform network security analysis on the equipment that they design and manufacture. This experience gives Dr. Salter the unique, industry-wide perspective that she brings to the classroom.
