Trustworthy computing

The term trustworthy computing (TwC) has been applied to computing systems that are inherently secure, available and reliable. The Committee on Information Systems Trustworthiness’ publication, Trust in Cyberspace, defines such a system as one which

does what people expect it to do – and not something else – despite environmental disruption, human user and operator errors, and attacks by hostile parties. Design and implementation errors must be avoided, eliminated or somehow tolerated. It is not sufficient to address only some of these dimensions, nor is it sufficient simply to assemble components that are themselves trustworthy. Trustworthiness is holistic and multidimensional.
