Course Description:
This hands-on course provides in-depth training on Wireshark® and TCP/IP communications analysis. This course covers the use of Wireshark to identify the most common causes of performance problems in TCP/IP communications. Topics include traffic capturing techniques and analyzer placement, traffic filtering (capture/display), customized profiles, coloring rules, graphing, field interpretations and functionality of key TCP/IP communications. A strong emphasis is placed on understanding the normal behavior of ARP, DNS, IP, TCP, UDP, ICMP as well as HTTP/HTTPS. Students learn to identify latency issues, connection establishment concerns, service refusals and common indications of reconnaissance processes and breached hosts.

 

Upon completion of this course the participant will understand how to use Wireshark efficiently to spot the primary sources of network performance problems.
