TL;DR: Federal supply chain guidance is pushing software security toward continuous validation, SBOM-driven visibility, and stronger controls for APIs, MFA, and zero trust across users and machines, according to Salt. The practical shift is away from manual, point-in-time assurance toward runtime governance that can actually track modern integration sprawl.

By the numbers:
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes - and as quickly as 9 minutes in some cases.
Questions worth separating out
Q: What breaks when supply chain security relies on point-in-time authorization?
A: Point-in-time authorization fails when code, APIs, and machine identities keep changing after approval.
Q: Why do APIs create identity governance risk across machine and human access?
A: APIs often carry the real access decision for service accounts, tokens, and human sessions.
Q: What do organisations get wrong when they say they have MFA everywhere?
A: They often count coverage without checking the quality of the factors.
Practitioner guidance
- Implement continuous validation for release pipelines Require post-approval checks for code integrity, dependency changes, and runtime drift so ATO-style evidence does not expire at deployment time.
- Inventory API trust relationships as governed assets Map every business-critical API to its calling identities, data flows, and privilege scope.
- Separate human authentication policy from machine access policy Use MFA for interactive users, but define distinct controls for service accounts, tokens, and certificates.
What's in the full article
Salt's full article covers the operational detail this post intentionally leaves for the source:
- How Salt maps API protection to real deployment and integration scenarios across modern application stacks
- Specific examples of where MFA and zero trust controls become difficult in machine-heavy environments
- The article's practical discussion of SBOM, code integrity, and supply chain validation in enterprise workflows
- Why the vendor argues traditional tooling and manual approaches cannot keep pace with today's system complexity

Continuous validation is becoming the only defensible answer to modern supply chain risk. Static approvals assume the trusted state remains stable long after sign-off, but the article describes a world where code, APIs, and machine access change continuously. That is exactly where point-in-time assurance collapses. In identity terms, the same logic applies to service accounts and tokens that outlive the change that created them. Practitioners should treat continuous evidence as a control requirement, not an operational luxury.
A question worth separating out:
Q: Which controls matter most when software supply chain risk meets zero trust?
A: The most useful controls are continuous validation, least privilege, runtime session monitoring, and a governed inventory of machine identities. Zero trust is not a single product decision. It is a discipline for proving that authenticated access is still appropriate after deployment, integration, and change.
