이 섹션에는 소스 코드 외부에 있지만 제작 중인 제품의 보안에는 여전히 중요한 내용이 모두 포함되어 있습니다. 이 섹션에서 다루는 문제들은 소스 코드와 직접적으로 관련이 없기 때문에 나머지 섹션과 분리했습니다.

J2EE Misconfiguration: Missing Data Transport Constraint

Java/JSP

Abstract

사용자 데이터 제약 조건을 지정하지 않는 보안 제약 조건은 제한된 리소스가 전송 계층에서 보호된다는 것을 보장할 수 없습니다.

Explanation

web.xml 보안 제약 조건은 일반적으로 RBAC(Role-Based Access Control)에 사용되지만 선택적 user-data-constraint 요소로 콘텐트의 안전하지 않은 전송을 차단하는 전송 보증을 지정할 수 있습니다.

<user-data-constraint> 태그 안에서 <transport-guarantee> 태그는 통신의 처리 방법을 정의합니다. 전송 보증에는 3가지 수준이 있습니다.

1) NONE은 응용 프로그램에서 전송 보증을 요구하지 않음을 의미합니다.
2) INTEGRAL은 응용 프로그램에서 클라이언트와 서버 간에 전송되는 데이터를 전송 중에 변경할 수 없는 방식으로 전송할 것을 요구함을 의미합니다.
3) CONFIDENTIAL은 응용 프로그램에서 다른 엔티티가 전송 내용을 관찰할 수 없는 방식으로 데이터를 전송할 것을 요구함을 의미합니다.

대부분의 상황에서 INTEGRAL 또는 CONFIDENTIAL의 사용은 SSL/TLS가 필요함을 의미합니다. <user-data-constraint> 및 <transport-guarantee> 태그가 생략된 경우 전송 보증은 기본적으로 NONE으로 설정됩니다.

예제 1: 다음 보안 제약 조건은 전송 보증을 지정하지 않습니다.


<security-constraint>
    <web-resource-collection>
        <web-resource-name>Storefront</web-resource-name>
        <description>Allow Customers and Employees access to online store front</description>
        <url-pattern>/store/shop/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <description>Anyone</description>
        <role-name>anyone</role-name>
    </auth-constraint>
</security-constraint>
