Step into the world of advanced network analysis with our 4-day Wireshark specialization course. This intensive program is designed to equip attendees with the skills to unravel the complexities of network behaviors, performance bottlenecks, and potential security vulnerabilities. The training lays emphasis on key areas such as identifying performance glitches arising from path latency, pinpointing devices that drop packets, and validating the optimal configuration of network hosts. It goes a step further to analyze intricate dependencies, optimize application behaviors, and offer insights into the functionalities of TCP/IP networks.

In the modern digital environment, understanding the behavior and security of applications during various stages is paramount. This course hones in on techniques to verify application security during crucial junctures like login, launch, and data transfer. Participants will also learn to spot anomalies in network traffic, indicative of potentially compromised hosts, and develop proficiency in using graphical representations to report issues such as server performance slowdowns, packet losses, and network congestion. By the end of this immersive course, attendees will have transformed into network analysis mavens, adept at leveraging Wireshark for optimal network health and security.
