Actions de réponse (7 étapes)
Étapes concrètes et exemples de commandes que les équipes SOC/SRE doivent exécuter dans l'ordre
-
1Identify exposure identify
grep -r 'kernel' . | 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 `kernel` を grep し、稼働しているサービス・バージョンを把握する。
-
6Apply patch patch
Upgrade kernel to 5.14.0-570.62.1.el9_6.tuxcare.1.els8ステージング環境で 5.14.0-570.62.1.el9_6.tuxcare.1.els8 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。
-
7Post-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。
