Security Threat Modeling

Trigger Boundary

• •Use when security controls, abuse paths, or compliance obligations must be defined.
• •Do not use for non-security product prioritization; use requirement or roadmap skills.
• •Do not use for purely aesthetic UI decisions.

Goal

Reduce exploitable risk with verifiable security controls.

Inputs

• •Change scope and risk profile
• •Domain evidence for asset, boundary, and abuse-path modeling for system threats
• •Operational, compliance, and rollout constraints

Outputs

• •Threat model with prioritized mitigations
• •Decision log for asset, boundary, and abuse-path modeling for system threats
• •Verification checklist with measurable pass-fail criteria

Workflow

1. •Clarify outcomes and hard constraints for asset, boundary, and abuse-path modeling for system threats.
2. •Produce options and select an approach for asset, boundary, and abuse-path modeling for system threats.
3. •Evaluate trade-offs across security, performance, operability, and maintainability.
4. •Verify decisions using mitigation coverage review for top abuse scenarios.
5. •Publish decisions, residual risks, and accountable follow-up actions.

Quality Gates

• •Scope and assumptions for asset, boundary, and abuse-path modeling for system threats are explicit and reviewable.
• •Decision rationale is backed by evidence instead of preference.
• •Rollout and rollback criteria are defined when production impact exists.
• •Residual risks have owners, due dates, and verification steps.

Failure Handling

• •Stop when high-impact threats lack mitigations or owners.
• •Escalate when accepted risk exceeds team policy thresholds.
