Abstract: A method, according to one approach, is for identifying relevant policies applicable to a configuration of a computing environment. The method includes preprocessing the configuration of the computing environment and policies. The preprocessing includes splitting the configuration into entities and respective metadata. Moreover, summaries of the entities and the respective metadata are created using a trained machine learning model. The method further includes computing relevance and adherence of the entities with the policies by processing at least one of the summaries. The entities are grouped into configuration blocks based at least in part on embedded vectors in the entities. Relevance and adherence of the configuration blocks are further computed with the policies. Furthermore, a final report is prepared by selecting those configuration blocks with a highest relative relevance and lowest relative adherence.
