The software supply chain demands more visibility into components and providers
Businesses want to know which libraries and dependencies comprise their applications to react faster to new vulnerabilities.
News summary
A business application can contain hundreds or thousands of components that have not been developed internally. Open-source libraries, commercial packages, base images, and external services form a digital supply chain that is difficult to visualise. When a critical vulnerability appears in one of those components, the first question is simple yet sometimes difficult to answer: are we using it?
This is why component inventories and SBOM, structured lists of the pieces that form part of a software, are gaining relevance. Their value lies not only in generating a document, but in being able to link a new vulnerability to the affected applications and prioritise the response.
Control also starts earlier. Reviewing the provenance of dependencies, pinning versions, validating signatures, and protecting development repositories reduces the risk of a manipulated component reaching production. The identities used by integration and deployment pipelines must also be treated as critical credentials.
For companies purchasing software, the supply chain includes providers. Enquiring how they manage vulnerabilities, updates, and remote access helps to understand what risk is being outsourced.
It is not about eliminating dependencies, which is practically impossible, but about having sufficient visibility to act quickly.
For development teams, a best practice is being able to trace from a specific application to the vulnerable component and vice versa. This traceability turns the inventory into an operational tool. Automating it within the pipeline prevents information from becoming outdated shortly after generating an SBOM.
What is changing in software management
A business application can contain hundreds or thousands of components that were not developed in-house: open-source libraries, commercial packages, base images and external services make up a digital supply chain that is hard to map. When a critical vulnerability appears in one of those components, the first question is simple and sometimes hard to answer: are we using it?
That is why component inventories and SBOMs, structured lists of the pieces that make up a piece of software, are gaining relevance. Their value lies not just in producing a document, but in being able to link a new vulnerability to the affected applications and prioritise the response.
Why it also matters to those who buy software
Control starts before the vulnerability appears: reviewing where dependencies come from, pinning versions, validating signatures and protecting development repositories reduces the risk of a tampered component reaching production. The identities used by CI/CD pipelines must also be treated as critical credentials.
For companies that buy software rather than build it, the supply chain includes their vendors. Asking how they manage vulnerabilities, updates and remote access helps clarify what risk is being outsourced.
What to review
Concrete steps to gain visibility without trying to eliminate every dependency:
- Having an inventory or SBOM for critical applications, even a basic one.
- Being able to link a specific vulnerability to the applications that use that component.
- Pinning versions and validating the origin of dependencies before adding them.
- Asking software vendors how they manage their own vulnerabilities and access.
Frequently Asked Questions
- What is an SBOM?
- It is a structured list of the components that make up a piece of software, useful for quickly knowing whether a vulnerability affects a specific application.
- Is this only relevant for large software companies?
- No. Any company using applications with many dependencies, whether in-house or third-party, benefits from having visibility into its components.
- Do we need to eliminate all external dependencies?
- That isn't realistic or necessary. The goal is having enough visibility to act quickly when a vulnerability appears.
