About Network Monitoring Tools
Network monitoring and packet analysis tools capture, inspect, and index network traffic for security analysis. The category includes packet analyzers like Wireshark and tcpdump that decode protocols at the packet level, full-packet capture systems like Arkime that store and index complete traffic histories for forensic search, and network security monitors like Zeek that generate session logs and protocol transcripts from live traffic. Packet analyzers are the primary tool for protocol-level debugging and incident investigation, letting analysts inspect individual packets, follow TCP streams, and decode application-layer protocols. Full-packet capture systems store traffic at scale, so analysts can reconstruct sessions days or weeks after an incident. Zeek takes a different approach, producing structured logs of network sessions, DNS queries, TLS certificates, and file transfers without storing raw packets, which scales better for high-bandwidth environments. Tools like Kismet monitor 802.11 wireless traffic, extending packet analysis to WiFi networks. The category overlaps with detection engineering, since network monitoring tools feed data into IDS/IPS systems and SIEM platforms for alert generation.
