Abstract

Described are security critical data containers for platform code, comprising a Get container and Set container that allow data to be marked as security critical for critical usage of that data, but left unmarked for non-critical usage. The number of critical methods in the code is reduced, facilitating better code analysis. A container's method may be marked as security critical, with the only access to the data via the method. By using a generic class for a Get container, access to the critical data only occurs through the property on the class, which is marked as critical. The field pointing to the generic class instance need not be critical, whereby initialization or existence checking may remain non-critical. The Set container handles security critical situations such as data that controls whether code can elevate permissions; a set method is marked as critical, while other methods can be accessed by non-critical code.
