A common scenario is to use TCPdump to grab the packet output and load that data into Wireshark. Using the available data (perhaps via flow/cloud logs or JA3/data etc.) it is identified that this specific instance requires further packet investigation. Let's break down a forensic investigation scenario with Wireshark:Ī network or security analyst is routinely assigned a ticket for deeper inspection or is working to respond to an event. The ultimate goal for analysis is to find the problem, gather the evidence and solve/respond to the incident as quickly as possible, with the fewest possible “casualties.” You wouldn’t turn down evidence in a case if it was easily available to you.

Whether in the cloud, where TLS standards are managed and enforced by your cloud provider, or on-prem, organizations are moving to higher levels of end-to-end SSL/TLS encryption for improved compliance and security - TLS 1.3 and Perfect Forward Secrecy (PFS) being the protocol in place today.Īs with any investigation, the evidence is key to reach the solution - the more facts and evidence you have, the better - the more details and clues, the faster you can come to the final conclusion for action.

As the world’s leading network traffic analyzer, Wireshark is heavily relied upon to analyze network traffic in real-time for troubleshooting, event inspection and forensic analysis on flagged anomalies and threat detection. Wireshark is a core application in any security professional or systems administrators toolbox.
