Measuring the Trustworthiness of Software
There are relations between these two models , but they are not perfectly mapped . ISO 25010 ’ s quality characteristics for Reliability and Security mirror similar characteristics in the IIC Trustworthiness model . However , IIC ’ s Resilience is addressed by two sub-characteristics under ISO 25010 ’ s Reliability characteristic⎯Fault Tolerance and Recoverability .
IIC ’ s Privacy characteristic is addressed by Confidentiality , a sub-characteristic under ISO 25010 ’ s Security characteristic . The current published version of ISO 25010 does not have a quality characteristic for Safety . ISO 25010 is currently being revised and will contain a ninth quality characteristic devoted to Safety in its next publication . Reliability and Security will remain largely identical to their construction in the 2011 publication .
Figure 2-1 . Relation of IIC Trustworthiness characteristics to the quality characteristics in the revised ISO / IEC 25010 .
Figure 2-1 displays a partial representation of the revised ISO 25010 quality model with the relevant quality characteristics of Reliability and Security highlighted in light blue . The new Safety characteristic is highlighted in a dashed gray . The IIC Trustworthiness characteristics are presented in red with pointers to their related ISO 25010 characteristic or sub-characteristic .
