Study Notes
Wireshark Decode As
- Using the Decode As option in Wireshark allows you to override Wireshark's automatic protocol detection and specify a protocol to decode the traffic as.
- To specify that traffic to port 10002 should be decoded as HTTP, go to Analyze > Decode As, select the protocol (HTTP) and enter the port number (10002).
Packet Analysis
- Right-clicking on a packet in a stream and selecting 'Decode As' in Wireshark allows you to decode a specific packet or a range of packets as a different protocol.
- Scrolling through the protocols listed on the right in Wireshark when using the Decode As option helps to select the desired protocol.
Incident Response and Recovery
- The first task of recovery after an incident has been contained is to identify and collect evidence for legal proceedings.
- Evidence for legal proceedings should be identified during the initial stages of the recovery process.
- Individuals performing recovery operations must be trained in handling evidence to ensure its integrity and admissibility in court.
