According to SANS NewsBites Vol. XII, Issue 53 recently published there’s a lack of 3rd party developer support for some security features Microsoft introduced already years ago. We at ERNW have made similar observations when performing security assessments of COTS [commercial off-the-shelf] software. We therefore created a methodology, a proof of concept tool and a metric to test and to rate closed source software, where (amongst other approaches) these security features are checked and their (non-) presence contributes to an overall evaluation as for the trustworthiness of the applications in question. The concept “How to rate the security in closed source software” was presented to the public at Troopers10 and at Hack in the Box 2010 in Amsterdam. The slides can be found here.
