After the system has been modeled, it is now time to address the question of "what can go wrong?". This question must be explored with the inputs from the first step in mind; that is, it should focus on identifying and ranking threats within the context of the specific system being evaluated. In attempting to answer this question, threat modelers have a wealth of data sources and techniques at their disposal. For illustration purposes, this cheatsheet will leverage STRIDE; however, in practice, other approaches may be used alongside or instead of STRIDE. STRIDE is a mature and popular threat modeling technique and mnemonic originally developed by Microsoft employees. To facilitate threat identification, STRIDE groups threats into one of six general prompts and engineers are encouraged to systematically consider how these general threats may materialize within the context of the specific system being evaluated. Each STRIDE threat may be considered a violation of a desirable security attribute; the categories and associated desirable attributes are as follows STRIDE provides valuable structure for responding to the question of "what can go wrong". It is also a highly flexible approach and getting started need not be complex. Simple techniques such as brainstorming and whiteboarding or even games may be used initially. STRIDE is also incorporated into popular threat modeling tools such as OWASP's Threat Dragon and Microsoft's Threat Modeling Tool. Additionally, as a relatively high-level process, STRIDE pairs well with more tactical approaches such as kill chains or MITRE's ATT&CK (please refer to this article for an overview of how STRIDE and ATT&CK can work together). After possible threats have been identified, people will frequently rank them. In theory, ranking should be based on the mathematical product of an identified threat's likelihood and its impact. A threat that is likely to occur and result in serious damage would be prioritized much higher than one that is unlikely to occur and would only have a moderate impact. However, these both can be challenging to calculate, and they ignore the work to fix a problem. Some advocate for including that in a single prioritization.
