 ## Addressing Each Question
 
-There is no universally accepted industry standard for the threat modeling process, no "right" answer for every use case. However, despite this diversity, most approaches do include the the processes of system modeling, threat identification, and risk response in some form. Inspired by these commonalities and guided by the four key questions of threat modeling discussed above, this cheatsheet will break the threat modeling down into four basic steps: application decomposition, threat identification and ranking, mitigations, and review and validation. There are processes that are less aligned to this, including PASTA and OCTAVE, each of which has passionate advocates.
