Trusted FoundrynounMWEFacility that produces integrated circuits with a higher level of integrity assurance.verified
Trusted Identification ForwardingnounMWEIdentification method used in information system networks whereby the sending host can verify an authorized user on its system is attempting a connection to another host. The sending host transmits the required user authentication information to the receiving host.verified
Trusted PathnounMWEA mechanism by which a user (through an input device) can communicate directly with the security functions of the information system with the necessary confidence to support the system security policy. This mechanism can only be activated by the user or the security functions of the information system and cannot be imitated by untrusted software.verified
Trusted Platform Module ChipnounMWEA tamper-resistant integrated circuit built into some computer motherboards that can perform cryptographic operations (including key generation) and protect small amounts of sensitive information, such as passwords and cryptographic keys.verified
Trusted PortsnounMWETrusted ports are ports below number 1024 usually allowed to be opened by the root user.verified
Trusted ProcessnounMWEProcess that has been tested and verified to operate only as intended.verified
Trusted RecoverynounMWEAbility to ensure recovery without compromise after a system failure.verified
Trusted TimestampnounMWEA digitally signed assertion by a trusted authority that a specific digital object existed at a particular time.verified
Trusted zonenounMWEA channel in which the end points are known and data integrity is protected in transit. Depending on the communications protocol used, data privacy may be protected in transit. Examples include secure socket layer, internet protocol security and a secure physical connection.verified
Trustee AccountnounMWEa savings account deposited by someone who makes themselves the trustee for a beneficiary and who controls it during their lifetimeverified
Trustee-Beneficiary RelationnounMWEthe responsibility of a trustee to act in the best interests of the beneficiaryverified
Trustworthy AinounMWETrustworthy AI has three components: (1) it should be lawful, ensuring compliance with all applicable laws and regulations (2) it should be ethical, demonstrating respect for, and ensure adherence to, ethical principles and values and (3) it should be robust, both from a technical and social perspective, since, even with good intentions, AI systems can cause unintentional harm. Characteristics of Trustworthy AI systems include: valid and reliable, safe, secure and resilient, accountable and transparent, explainable and interpretable, privacy-enhanced, and fair with harmful bias managed. Trustworthy AI concerns not only the trustworthiness of the AI system itself but also comprises the trustworthiness of all processes and actors that are part of the AI system’s life cycle. Trustworthy AI is based on respect for human rights and democratic values.verified
trustworthy regrading mechanismnounMWEA validated, policy-governed process or control that an organization is authorized to deploy when changing the security classification, labels, or other attributes assigned to information — particularly when data crosses between security domains or trust boundaries with differing policies. It is a trusted process authorized to re-classify and re-label data in accordance with a defined policy exception, and its distinguishing characteristic is that the reassignment action itself must be performed only through this controlled channel rather than through ad-hoc or manual means. Validated regrading mechanisms are used by organizations to provide the requisite levels of assurance for attribute reassignment activities. In practice, as seen in both NIST SP 800-53 (control AC-16(9)) and authority documents such as the DoD CMMC Assessment Guide and the Canadian Centre for Cyber Security guidance, enforcement of cross-domain information flow policy includes implementing trustworthy regrading mechanisms to reassign security attributes and security labels alongside hardware-enforced one-way flows and outright transfer prohibitions.verified
Trustworthy SystemnounMWEComputer hardware, software and procedures that— 1) are reasonably secure from intrusion and misuse; 2) provide a reasonable level of availability, reliability, and correct operation; 3) are reasonably suited to performing their intended functions; and 4) adhere to generally accepted security procedures.verified
