1
Identify exposure identify
```
grep -r 'deserialization' . | grep -v node_modules
```
リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で deserialization を grep し、稼働しているサービス・バージョンを把握する。
7
Post-deployment verification verify
```
Confirm patched version is live in production
```
