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.

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.
