An opinionated selection of shapes for the threat modeling.
Data Flow Diagramming is a simple diagramming technique used to gain an understanding of how data flows in an application or system.
DFDs are excellent for getting a bird's-eye view of a system to facilitate threat modeling.

This library intentionally uses just 5 items:

  • External entity: Anything outside your control. Examples include people and systems run by other organizations or even divisions.
  • Process: Any running code, including compiled, scripts, shell commands, SQL stored procedures, et cetera.
  • Data store: Anywhere data is stored, including files, databases, shared memory, S3, cookies, et cetera.
  • Data flows: All the ways that processes can talk to data stores or each other.
  • Trust boundary: Should be a closed shape, usually a box. Clearly show what's inside, in a way that OG arcs often fail to do.
