Lessons learned from recent major supply chain attacks and how to vet your dependencies.
Your Code is Only 10% Your Code
Modern applications are built on a mountain of open-source libraries. The Software Supply Chain attack vector targets these dependencies. Instead of hacking you directly, attackers hack a library you trust (like the SolarWinds or Log4j incidents).
The Software Bill of Materials (SBOM)
You cannot secure what you don't know you have. An SBOM is a formal inventory of all the components, libraries, and modules that make up your software. It is essentially the "ingredients label" for your application.
- Vulnerability Management: When the next "Log4j" happens, an SBOM allows you to instantly search across your entire estate to see if you are affected.
- License Compliance: Ensuring you aren't accidentally using GPL code in proprietary software.
Typosquatting and Dependency Confusion
Attackers publish malicious packages with names similar to popular ones (e.g., react-dom vs rract-dom). Developers making a simple typo can inadvertently install malware on their build server. Private package feeds and strict lockfiles are essential defenses against this.

- Identify critical assets and map dependencies.
- Implement continuous monitoring with automated tools like VulnSentry.
- Establish a robust incident response plan.
Stay vigilant. The threat landscape is constantly evolving, and static defense strategies are no longer sufficient.
