This hands-on course will teach you how to quickly understand and analyze core network protocols. Grab your copy of Wireshark, as you'll dive into the important underlying packets that support your business applications.
What you will learn:
There are billions of packets flying through the network every minute. Which packets are important? Which packets hold the key to troubleshooting network and application problems? In this course, Analyzing Network Protocols with Wireshark, you will gain the ability to capture, interpret, and analyze network problems at the packet level. First, you'll explore core protocols and services, such as ARP, IPv4, and DHCP. Next, you'll explore how the UDP and DNS protocols work. Finally, you will learn how to analyze application traffic based on HTTP and TLS. Upon completion of this course, you will have the packet analysis skills and knowledge with Wireshark needed to isolate and resolve network problems.
