Typical severity: High. Likelihood of attack: Medium. An adversary conducts supply chain attacks by the inclusion of insecure third-party components into a technology, product, or code-base, possibly packaging a malicious driver or component along with the product before shipping it to the consumer or acquirer.
Assess software and hardware during development and prior to deployment to ensure that it functions as intended and without any malicious functionality. This includes both initial development, as well as updates propagated to the product after deployment. | Don't assume popular third-party components are free from malware or vulnerabilities. For software, assess for malicious functionality via update/commit reviews or automated static/dynamic analysis prior to including the component within the application and deploying in a production environment.
