Day 4: Network Forensics
🕵️♂️ What is Network Forensics?
Network Forensics is the art of digging through digital footprints on the network, tracking down security incidents, and piecing together what went down. It’s like CSI, but for data packets.
- Network forensics involves the monitoring and analysis of network traffic to gather evidence and investigate security incidents.
- Tools like Wireshark are the go-to for packet capture and analysis in network forensics.
- Anomalies in network traffic can tip you off to potential security breaches.
- Timestamps and logs are your bread and butter for reconstructing events during an investigation.
- A deep understanding of network protocols, especially TCP/IP, is key to effective analysis.
🗂️ PCAP Files
PCAP (Packet Capture) files are your treasure maps—they store the network traffic captured during monitoring, ready for you to crack them open and find the buried loot.
- PCAP files can be analyzed using tools like Wireshark to identify patterns and potential security issues.
- Capturing packets in real-time with tools like tcpdump creates these files for analysis.
- These files are a goldmine for troubleshooting network issues with detailed packet-level info.
- You can filter, search, and extract specific data from PCAP files to dig into network activity.
