Extended Description

Many modern hardware and software products are built by combining multiple smaller components together into one larger entity, often during the design or architecture phase. For example, a hardware component might be built by a separate supplier, or the product might use an open-source software library from a third party.

Regardless of the source, each component should be sufficiently trusted to ensure correct, secure operation of the product. If a component is not trustworthy, it can produce significant risks for the overall product, such as vulnerabilities that cannot be patched fast enough (if at all); hidden functionality such as malware; inability to update or replace the component if needed for security purposes; hardware components built from parts that do not meet specifications in ways that can lead to weaknesses; etc. Note that a component might not be trustworthy even if it is owned by the product vendor, such as a software component whose source code is lost and was built by developers who left the company, or a component that was developed by a separate company that was acquired and brought into the product's own company.

Note that there can be disagreement as to whether a component is sufficiently trustworthy, since trust is ultimately subjective. Different stakeholders (e.g., customers, vendors, governments) have various threat models and ways to assess trust, and design/architecture choices might make tradeoffs between security, reliability, safety, privacy, cost, and other characteristics.
