Response Actions (7 steps)

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

1
Identify exposure identify
```
grep -r 'salt' . | 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 `salt` 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 salt to 2015.8.10, 2015.8.13, 2016.3.4, 2016.3.6, 2016.3.8, 2016.11.3, 2016.11.5, 2016.11.10, 2017.7.8, 2019.2.0rc1, 2019.2.5, 2019.2.8, 3000.6, 3001.4, 3002.5
```
ステージング環境で 2015.8.10, 2015.8.13, 2016.3.4, 2016.3.6, 2016.3.8, 2016.11.3, 2016.11.5, 2016.11.10, 2017.7.8, 2019.2.0rc1, 2019.2.5, 2019.2.8, 3000.6, 3001.4, 3002.5 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。
