Software supply chain security, operationalized in 5 stages

Software vendors have long been focused on dealing with the problem of software vulnerabilities, but software supply chain vulnerability is actually much broader, encompassing all of the code that vendors import, build and ship. In other words, the software supply chain extends across the entire software development lifecycle (SDLC), including all of the processes and systems that interact with it. Therein lies the problem: the need for software vendors to secure everything, whereas bad actors need only a single weak link to exploit.

Fear not, we have the roadmap to guide you through the journey of securing your software supply chain.

Journey To Supply Chain Security

JUNE 11, 2023: Executive Order Mandate 14028 goes into effect, complete with legal repercussions for those who don’t comply.

In response to the growing threat of software supply chain attacks, as well as the reluctance of software vendors to embrace a security-first mindset, the US government has taken the exceptional step of imposing supply chain security requirements. Effective from June 2023, any vendor of software deployed at (or even coming in contact with systems at) US government agencies or departments must comply or risk losing their contract. While the guidelines are extensive, key requirements for software vendors include:

  • SBOMs – vendors must provide a machine-readable list of all the components that make up their software application, including third party libraries and integrations.
  • Secure Software Development – vendors must adopt secure software development best practices, starting with detecting and resolving security vulnerabilities

In much the same way that European Union (EU) General Data Protection Regulation (GDPR) requirements were adopted worldwide for fear of losing out on EU revenue, the US’ secure supply chain requirements are likely to become just as widespread.
With that in mind, this chapter focuses on Stage 1 (Observable Chaos) of the Secure Supply Chain Journey, which can help organizations get started on the path to securing their software supply chain and complying with US requirements.
