注解

以下列表描述了默认由 ASP.NET 引发事件的功能 WebAuthenticationFailureAuditEvent 。

• 表单身份验证。 虽然成功审核包括经过身份验证的用户名;失败审核不包括用户名，因为它们通常由未通过解密或验证的票证导致的。 两者都包含客户端 IP 地址。 相关的事件审核代码为 AuditFormsAuthenticationFailure。

• 会员。 成功和失败审核都包含尝试的用户名。 这两种审核形式都不会包含尝试的密码，因为这将有可能在日志中保留有效的密码。 相关的事件审核代码为 AuditMembershipAuthenticationFailure。

WebAuthenticationFailureAuditEvent引发 时，默认情况下会更新审核身份验证失败事件引发的性能计数器。 若要在系统监视器 (PerfMon) 中查看此性能计数器，请在“添加计数器”窗口中选择“ASP.NET性能对象”下拉列表中的“身份验证失败事件引发的性能”计数器，然后单击“添加”按钮。 有关详细信息，请参阅 将系统监视器 (PerfMon) 与 ASP.NET 应用程序配合使用。
