Supply Chain Security
Supply chain security manages cyber risks introduced through products, software, services, and organizations an enterprise depends on.
In simple terms
A business can be affected by a compromised software update or a supplier outage even when its own systems are well maintained.
Technical explanation
Controls can include provenance, supplier assessment, secure procurement, contractual expectations, update verification, monitoring, and alternate sourcing. Risk extends beyond direct vendors to components and subcontractors.
Dependencies include software components, update channels, service providers, and subcontractors. Provenance and alternate plans reduce the chance that one compromised or failed link disrupts the whole service.
Examples in practice
A company checks the origin of a software package and plans an alternate provider for a critical service before an outage occurs.
A signed update arrives from an expected vendor but includes an unfamiliar component. The company pauses rollout, verifies the release through the vendor's channel, and tests it before deployment.
Why it matters
Dependencies can carry security and continuity failures across organizational boundaries.
