Make trust explicit at every boundary.
A valid input can still cause an unauthorized action. Security work starts by following an input to the state it can change, then making ownership, permission, and evidence explicit.
A USEFUL ENGAGEMENT CAN INCLUDE
- 01Trust-boundary and sensitive-data mapping
- 02Authorization and failure-mode review
- 03Prioritized hardening work with verification evidence
Where does a security review begin?+
With the assets, actors, and exposed workflows of the actual system. The review follows concrete paths from untrusted inputs to sensitive actions, then prioritizes changes by exposure and impact.
Does a review guarantee the absence of vulnerabilities?+
No. A review is bounded evidence about a specific system and point in time. The useful outcome is clearer trust boundaries, verified fixes, and repeatable checks as the system changes.
