Perform Deep Packet Analysis

Answer - A.

If you want to have a packet analysis tool, you need an external tool.

Wireshark is one such tool that will give you a detailed packet tracing.

Options B, C and D are all incorrect since these tools cannot conduct deep packet analysis.

The correct answer to the question is A. Wireshark.

Wireshark is a popular open-source packet analysis tool that allows you to capture and analyze network traffic in real-time. It can be installed on your local computer or on an EC2 instance and used to analyze packets that are being sent to your EC2 instance. With Wireshark, you can view the contents of each packet, identify the source and destination of the packets, and analyze network traffic patterns.

AWS CloudTrail is a service that provides a record of actions taken by a user, role, or an AWS service in the AWS Management Console, AWS Command Line Interface, and other AWS services. CloudTrail can help you monitor and audit AWS API calls made to your account, but it does not capture packet-level information.

AWS CloudWatch is a monitoring service for AWS resources and applications. It provides data and actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. It does not provide packet-level information.

AWS VPC Flow Logs is a feature that captures information about the IP traffic going to and from network interfaces in a VPC. It can help you troubleshoot connectivity and security issues, analyze traffic flows, and capture network statistics. However, VPC Flow Logs do not provide packet-level information, only metadata about network traffic such as source and destination IP addresses, ports, protocol, and packet counts.

Therefore, Wireshark is the best option for performing a deep packet analysis of traffic sent to an EC2 instance.
