5-3Scaling Cybersecurity Defenses and DevSecOps

An engineer is asked to define an SBOM for a supply chain program. Which definition does the NTIA report give?

A formal record of componentsCorrect · your answerCorrect.
A list of approved vendorsA vendor list names suppliers rather than components.
A scan of running processesRuntime scanning observes behavior rather than composition.
A register of open incidentsAn incident register tracks events rather than software content.

Correct.

Why A

The NTIA report defines an SBOM as a formal record containing the details and supply chain relationships of various components used in building software.
