Feedback Loop

Feedback Loop: A mechanism that feeds findings and outcomes back into controls, processes, and decisions. It should be documented, assigned to an owner, measured, and reviewed at defined intervals.

How it works and where it fits

Feedback Loop places security within the lifecycle of software and technical change. Requirements, architecture, implementation, testing, release, and maintenance affect one another. The earlier a weakness or unsafe assumption is identified, the more precisely it can be corrected without relying solely on downstream security products.

Practical security relevance

Practical implementation requires explicit quality criteria, reviewable changes, and a traceable supply chain. Automated checks provide rapid feedback but do not replace threat modeling or manual analysis of security-critical logic. Dependencies, build systems, artifacts, and secrets need protection alongside source code; operational and incident findings feed back into development.
