Scan before you publish
Supply Chain
Exposed
We defend software in the wrong place, too late, with data we can't trust. The fix is at the source.
Almost nothing you run is code you wrote. It arrives from registries you do not control, vouched for by catalogs and tools you are told to trust, and installed by machines while you sleep. That chain of trust is the softest target in computing, and it is hit every day. Malware is uploaded straight to the registries developers pull from. Vulnerabilities are weaponized before they are even disclosed.
The industry keeps looking for the danger in the wrong place, and always too late. Registries publish first and scan never. Waiting periods start their clock after the attacker has already shipped. The catalog everyone treats as ground truth records what is convenient for vendors and misses the malware landing on your machine. The expensive tools meant to catch all of it guess at what you installed instead of asking the one system that already knows.
Underneath every chapter here is a single move. Put the check where the software actually enters, at publish and at install, and feed it data that is free, fast, and good enough to trust. Catch the threat at the source, before it can run, instead of counting the damage after.
This is a short book about doing that. It is about the registries, the catalog, and the tooling that could act tomorrow, and the excuses that have kept them from it.
