Get Wireshark Lab Ssl Solution

This guide provides clear instructions on how to complete the Wireshark Lab SSL Solution document effectively. You will find step-by-step directions tailored to enhance your understanding and successful submission of the form.

Follow the steps to complete the form successfully.

1. Use the 'Get Form' button to obtain the form and open it in your preferred editor.
2. Begin with the section where you need to capture packets in an SSL session. This entails visiting an e-commerce site and initiating a purchasing process without completing the transaction. After capturing the relevant packets using Wireshark, ensure you apply a filter to display only the Ethernet frames that contain SSL records sent from your host.
3. Once you have captured the packets, examine the displayed Ethernet frames. For the first eight frames, identify the source (client or server), count the number of SSL records included, and list the types of SSL records present. Additionally, create a timing diagram showing interactions between the client and server for each SSL record.
4. For each SSL record, start with the first three fields, which are the content type (one byte long), and document their lengths. Focus on the ClientHello record and identify the value of the content type, the existence of a nonce (or challenge), and if it lists supported cipher suites. Detail the algorithms in the first listed suite.
5. Next, locate the ServerHello record and determine if it specifies a chosen cipher suite, detailing the algorithms involved. Investigate whether it includes a nonce, its length, and the purpose of both client and server nonces in SSL. Additionally, check for a session ID and its function.
6. Find the client key exchange record and assess if it contains a pre-master secret, including its usage and encryption method. Document its encrypted length as well.
7. Investigate the Change Cipher Spec record and its size. Understand what is being encrypted in the Encrypted Handshake record, and whether the server sends similar records, noting the potential differences.
8. Explore how application data is encrypted, whether records include a MAC, and if Wireshark differentiates between encrypted data and the MAC.
9. Finally, provide commentary on any interesting observations from the trace, emphasizing unique findings or insights.
10. After completing all sections, review your entries, ensure accuracy, and then save your changes. You can download, print, or share the document as needed.
