Threat Modeling for Developers#

Threat modeling is the practice of systematically identifying what can go wrong in a system before it goes wrong. It is not a security team activity that happens once. It is a design activity that happens every time the architecture changes.

The output of threat modeling is not a report that sits in a wiki. It is a prioritized list of threats that becomes security requirements in the backlog.
