Threat modeling the TRAIL of Bits way
Summary: Trail of Bits describes TRAIL, its own threat modeling process, which extends Mozilla's single-component Rapid Risk Assessment to whole systems and incorporates parts of NIST SP 800-154 and the NIST SP 800-53 controls dictionary. The process maps in-scope components, places trust boundaries wherever security controls gate connections, groups components into trust zones, and builds threat actor paths to document design-level risks as threat scenarios, offered as either lightweight or comprehensive engagements.
Bottom line: The firm's stated aim is to break the cycle of receiving a security report, making a one-off fix, and then getting another ticket for the same problem - because a proper threat model exposes the design-level weaknesses of which individual vulnerabilities are symptoms.
