IT hardware validity checks are preventive and/or detective control measures that should be implemented to ensure appropriate data processing. An important component of enabling information integrity is sustaining data and task validity. Within this context, the purpose of an IT hardware validity check is to assist in ensuring that infrastructure processing activities are appropriate actions. Whereby, an appropriate action is one that conforms to a set of authorized rules that are considered to be correct or reasonable.
Determination of the validity of an IT hardware action is something a redundancy check is unable to perform. However, in conjunction with redundancy checks, validity checks provide considerable certainty that hardware processing and transfer of datum will be complete, accurate and creditable.
