Advanced Network Troubleshooting Scenarios
Master the command-line power of TShark for automated packet analysis and encrypted traffic decryption. You'll develop scripts to automate network captures, decrypt TLS traffic using pre-shared keys, and analyze HTTPS communication patterns. Starting with basic automation techniques, you'll progress to decrypting real application traffic and extracting critical security insights. The lab culminates in building an automated analysis pipeline that combines capture, decryption, and reporting—essential skills for security operations and incident response automation.

Challenge
Diagnose Performance Bottlenecks
In this objective, you'll diagnose network performance bottlenecks by analyzing PCAP files to identify latency and packet loss issues. You'll pinpoint whether slow application response times originate from the client, network, or server, investigate TCP reset issues causing disconnects, and analyze TCP window problems affecting data transmission.

Challenge
Apply Troubleshooting Methodologies
In this objective, you'll develop and execute systematic troubleshooting plans for complex network problems. You'll utilize Wireshark's expert information and statistical tools to accelerate problem identification, then correlate your packet-level findings with simulated NetFlow logs and monitoring alerts to build a complete picture of network issues.

Challenge
Troubleshoot Protocol-Specific Issues
In this objective, you'll troubleshoot specific protocol-related issues in practical contexts. You'll analyze DHCP and DNS traffic to diagnose configuration and resolution failures, investigate VoIP and video stream quality issues using specialized Wireshark tools, and detect traffic on non-standard ports to identify misconfigurations or potential security threats.

The Last Objective
Welcome to the final objective! This is your last chance to experiment in the environment.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
