Challenge
Capture an HTTPS Website and Session Keys in Wireshark Using Windows
In this challenge ,you will be provided with a virtualized Windows desktop where you will configure it to capture session keys for all TLS sessions using the Firefox browser.

Challenge
Filter the Captured Frames and Decrypt the Capture with the Session Keys
In this challenge, you will use information collected from the previous Challenge to filter out only the frames associated with the Globomantics website, and then apply the session keys to decrypt the messages.

Challenge
Examine the Decrypted TLS Handshake
In this challenge, you will take a deeper look at the TLS handshake. The handshake has many detailed components, and you will examine the Client Hello, Server Hello, and Certificate messages. There is an option to use an external website to examine more details of the handshake if you like.

Challenge
Capture an HTTPS Website and Session Keys in Wireshark Using Linux Desktop, and decrypt the messages
In this challenge, you will repeat the exercise of capturing an HTTPS website and the session keys, but this time in Linux. You will find the TCP session for the website, and then decrypt it with the session keys.

Challenge
Examine the HTTPS Session of a TLS 1.1 Server
In this last challenge, you will use Wireshark to capture a website and examine what happens when the browser does not support the version of TLS configured on the server.
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.
