hardware integritynounMWEThe assurance that any given hardware asset is not a counterfeit, or otherwise falsely represented as being whole and intact as measured against original specifications.verified
hardware mechanismnounMWEA security control implemented in physical circuitry or dedicated electronic components — rather than in software or firmware — that enforces a security policy by making a constrained behavior structurally impossible to override through software means. Because software is vulnerable to various forms of attack, hardware-enforced controls are more attractive: unauthorized reconfiguration cannot be achieved without physical access to the device. In standards practice, the term is used wherever a policy requirement must be made unconditional: NIST SP 800-53 control AC-4(7) invokes the concept directly, requiring that one-way information flows be enforced "using hardware mechanisms." Organizations use such controls at policy-enforcement points to govern information flows between systems, and standards bodies call attention to the trustworthiness of the filtering and inspection components — hardware, firmware, and software — that are critical to that enforcement.verified

Harmful BiasnounMWEHarmful bias can be either conscious or unconscious.

Approved hash functions are specified in FIPS 180 and are designed to satisfy the following properties: 1. (One-way) It is computationally infeasible to find any input that maps to any new prespecified output, and 2. (Collision resistant) It is computationally infeasible to find any two distinct inputs that map to the same output.verified
