Docker Networks

Overview

Evidence: Docker Networks Description: Collect Docker Networks. Category: Applications Platform: linux Short Name: docknetworks Is Parsed: Yes Sent to Investigation Hub: Yes Collect File(s): No

Background

Docker networks define how containers communicate with each other and external systems. Network configuration reveals bridge networks, overlay networks, host networking modes, and IP address allocations critical for understanding container connectivity and isolation.

Data Collected

This collector gathers structured data about docker networks.

Collection Method

This collector queries the Docker daemon via Docker Engine API to enumerate all Docker networks. It extracts network ID, name, driver type, scope, subnet configuration, gateway, connected containers, and network options.

Forensic Value

Network data identifies containers exposed to the host network (potential privilege escalation), custom networks used for lateral movement, or misconfigured network isolation. Analyzing network attachments helps map container communication paths and detect unauthorized network access or data exfiltration channels.
