the work was requested by Microsoft and carried out by Cure53 in late January and early February 2021. As noted, this test is a follow-up to the project reported as DAP-01, which was a large-scale invested. Comparatively, a smaller number of allocated days - namely eight days - was needed for this 2021 assessment. The focus of DAP-02 was solidly on the ‘delta’, meaning additions introduced since the methodology, just as last time, has guided the work of Cure53. All preparations were done in January 2021, namely in CW03, indicating that Cure53 could have a smooth start in CW04. Communications during the
