SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires scapy.

What problem does it solve?

Analysts and engineers can analyze PCAP captures and compute essential network statistics using Python, supported by a library of tested utility functions.

Core Features & Use Cases

  • Load PCAP files and filter by protocol to inspect IP, TCP, UDP, and ICMP traffic.
  • Compute graph/topology metrics (unique source/destination counts), inter-arrival time statistics, and per-minute traffic patterns to detect anomalies.
  • Use the helper suite (graph_metrics, iat_stats, packets_per_minute_stats, flow_metrics) to quantify traffic characteristics, detect port scans, DoS patterns, and beaconing.

Quick Start

Load a PCAP file with load_packets and immediately compute graph metrics, IAT statistics, and per-minute traffic using the built-in helper functions.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I compute inter-arrival time statistics from a PCAP file?▼

To compute inter-arrival time statistics from a PCAP file, load your packet captures and apply the iat_stats helper function to quantify traffic characteristics and detect anomalies like beaconing.

What is the best way to detect port scans and DoS patterns in network traffic?▼

Detect port scans and DoS patterns in network traffic by computing graph metrics and per-minute traffic patterns from PCAP captures using the packets_per_minute_stats and graph_metrics functions.

Can I use Python to filter PCAP traffic by specific protocols like TCP and UDP?▼

Yes, you can use Python to filter PCAP traffic by protocol to inspect IP, TCP, UDP, and ICMP traffic using the load_packets utility and scapy dependency.

Does this PCAP analysis approach work for large network datasets?▼

This PCAP analysis approach is applicable for security analysts and network engineers performing traffic characterization on small to medium PCAP datasets, rather than large-scale captures.

How do I count unique network flows and extract topology metrics from packet captures?▼

Count unique network flows and extract topology metrics from packet captures by loading packets and applying the flow_metrics and graph_metrics functions to derive unique source and destination counts.

Do I need scapy installed to compute entropy-based assessments on PCAP files?▼

Yes, you need scapy installed as a dependency to run entropy-based assessments and compute network statistics from PCAP files using the provided utility functions.
