Step 5: Capture and Analyze Network Traffic
Another skill that you will need as the network engineer for BallotOnline is being able to capture network traffic. It’s important to analyze network traffic to find and troubleshoot network issues. This method is commonly used to identify a malfunctioning network device or to detect a possible network issue, such as an ongoing network attack.
Normally, this process can take hours, days, or even weeks, depending on the size of the network and the specific traffic that you are trying to capture and analyze.
In this scenario, you will be provided with a captured network traffic and you will be directed to look for specific network packets.
You will use Wireshark, a popular open-source network traffic capture and analysis tool. To analyze the capture file provided to you, here is an introductory tutorial. ([login to view URL]) ( [login to view URL] )
FOLLOW THE STEPS in the Analyzing Network Traffic Using Wireshark Guide ATTACHED, and prepare a lab report with answers and screenshots to support your answers.
The lab report will be attached to your final technical report to demonstrate your proficiency in using the tool to do basic network analysis.

Step 7: Simulate a Network With Mininet
To demonstrate your understanding how network packets are transmitted in the cloud, you will use Mininet, ([login to view URL]) a popular open-source network simulator that can be used together with Wireshark. This demonstration will be part of your technical report.
FOLLOW THE STEPS in this Simulating a Network Using Mininet and Analyzing Packets Using Wireshark Guide. GO THIS LINK AND FOLLOW THE STEPS: ([login to view URL]).
During the lab, you will provision an EC2 instance in AWS using a preconfigured AWS Machine Image (AMI) and use the Mininet simulator in the EC2 instance to create two hosts. You will then use Wireshark to capture the packet exchanges.
