Dependency Confusion
Software Supply Chain Security
Simple
Dependency Confusion is a building block of "Software Supply Chain Security". In plain terms: dependencies, sbom, signing, provenance, dependency confusion, build pipeline integrity. This topic focuses specifically on dependency confusion and the core ideas you need to understand it.
Technical
Technically, Dependency Confusion involves the mechanisms, data structures and protocols that underpin software supply chain security. You will study how it is implemented, how it is configured, how it fails, and how its behavior shows up in logs, traffic or code.
Why it matters
SolarWinds-style attacks target the software factory itself.
Example
In a real organization, professionals working in supply chain engineer, devsecops, appsec. rely on dependency confusion to make decisions — for example, explaining an alert, hardening a system, or writing a finding in a report.
Practice idea
Build a small lab in a VM and experiment with dependency confusion using the related tools below. Document what you observe.
Deep dive
Read the official documentation and relevant RFCs/standards for Dependency Confusion. Explore edge cases, internals, and how attackers and defenders view it differently.
