The 15-Minute Patch, Reverse-Engineered: What Had to Be True?

This blog post presents a thought experiment and a hands-on 90-minute exercise to reverse-engineer what would be required to remediate or mitigate vulnerabilities within 15 minutes. It breaks the problem into measurable stages, highlights five mandatory capabilities (live inventory, rapid automated testing, replaceable infrastructure, pipeline-level governance, rehearsed rollback), and recommends using rapid mitigations for legacy systems where patching is impractical.
