# ACFP 範例：針對遭到入侵的登入資料進行自訂回應
<a name="waf-acfp-control-example-compromised-credentials"></a>

根據預設，規則群組執行的登入資料檢查會透過標記和封鎖請求來處理`AWSManagedRulesACFPRuleSet`遭到入侵的登入資料。如需規則群組和規則行為的詳細資訊，請參閱 [AWS WAF 詐騙控制帳戶建立詐騙預防 (ACFP) 規則群組](aws-managed-rule-groups-acfp.md)。

若要通知使用者他們提供的帳戶登入資料已遭入侵，您可以執行下列動作：
+ **將`SignalCredentialCompromised`規則覆寫為 Count** – 這會導致規則僅計數和標記相符請求。
+ **使用自訂處理新增標籤比對規則** – 設定此規則以符合 ACFP 標籤，並執行您的自訂處理。

下列保護套件 (Web ACL) 清單顯示先前範例中的 ACFP 受管規則群組，規則`SignalCredentialCompromised`動作會覆寫為計數。透過此組態，當此規則群組評估任何使用遭入侵登入資料的 Web 請求時，它會標記請求，但不會將其封鎖。

此外，保護套件 (Web ACL) 現在具有名為 的自訂回應`aws-waf-credential-compromised`和名為 的新規則`AccountSignupCompromisedCredentialsHandling`。規則優先順序是高於規則群組的數值設定，因此會在保護套件 (Web ACL) 評估中的規則群組之後執行。新規則會比對具有規則群組遭入侵憑證標籤的任何請求。當規則找到相符項目時，它會將 Block動作套用至具有自訂回應內文的請求。自訂回應內文會向最終使用者提供其登入資料遭到入侵的資訊，並提議採取動作。
