WCF Misconfiguration: Insufficient Audit Failure Handling

ABSTRACT

程序配置為在寫入審計日志失敗時不生成異常。

EXPLANATION

如果將 WCF 配置為在無法寫入審計日志時不拋出異常，操作失敗時程序不會收到通知，也不會審計重要的安全事件。

例 1：以下 WCF 配置文件中的 <behavior/> 元素指示 WCF 在 WCF 寫入審計日志失敗時不通知應用程序。

<behaviors>
<serviceBehaviors>
<behavior name="NewBehavior">
<serviceSecurityAudit auditLogLocation="Application"
suppressAuditFailure="true"
serviceAuthorizationAuditLevel="Success"
messageAuthenticationAuditLevel="Success" />
</behavior>
</serviceBehaviors>
</behaviors>
