Étapes concrètes et exemples de commandes que les équipes SOC/SRE doivent exécuter dans l'ordre

  1. 1
    Identify exposure identify 
    grep -r 'gcc-mingw-w64' . | 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 `gcc-mingw-w64` を grep し、稼働しているサービス・バージョンを把握する。

  2. 7
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 3 と同じログクエリでアラート再発が無いか継続監視。
