Response Actions (7 steps)

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
grep -r 'packagekit' . | 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 `packagekit` を grep し、稼働しているサービス・バージョンを把握する。
6
Apply patch patch
```
Upgrade packagekit to 0.8.17-4ubuntu6~gcc5.4ubuntu1.5+esm1
```
ステージング環境で 0.8.17-4ubuntu6~gcc5.4ubuntu1.5+esm1 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 3 で見つけた異常検知の続報チェックを含めること。
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。
