Which tool is commonly used to analyze network traffic in digital forensics?

Wireshark is widely regarded as the premier tool for analyzing network traffic in digital forensics. It allows forensic analysts to capture and view packets that flow across the network in real time, providing insights into the activities occurring on a network. By interpreting the data packets, investigators can uncover details about network communications, identify suspicious activities, and analyze protocols being used, which is crucial for identifying security breaches or unauthorized access.

Its user-friendly interface and robust features, such as advanced filter capabilities and the ability to dissect various network protocols, make it an invaluable tool for network traffic analysis. In contrast, the other options like FTK Imager, Autopsy, and EnCase are primarily focused on disk imaging and file system forensics rather than network traffic analysis. While they serve important roles in the broader field of digital forensics, they do not specifically cater to the intricate needs of network traffic investigation.
