Axis 2 Service Provider Misconfiguration: Missing Outbound Encryption

ABSTRACT

未加密的消息無法保護其保密性。

EXPLANATION

SOAP 消息級加密可確保真正的端到端保密性。可通過多種傳輸協議發送 SOAP 消息，例如 HTTPS、HTTP、TCP、SMTP、UDP 等。無論采用哪種傳輸協議，消息級加密都可確保消息的保密性。Web 服務之間的常見傳送情形是在各種服務之間轉發 SOAP 消息，因此通過消息級加密，消息發送者和接收者均無需擔憂中繼點之間的傳輸安全問題。

下列 Apache Axis 2 Rampart 配置不要求對輸出的消息進行加密，因為 <items> 標簽不包含 Encrypt 指令：

<service>
...
	<parameter name="OutflowSecurity">
		<action>
			<items>Timestamp Signature</items>
			...
		</action>
	</parameter>
</service>
