계: Encapsulation

캡슐화는 강력한 경계를 그리는 것입니다. 웹 브라우저에서는 사용자의 모바일 코드가 다른 모바일 코드에 의해 오용되지 않도록 하는 것을 의미합니다. 서버에서는 검증된 데이터와 검증되지 않은 데이터, 한 사용자의 데이터와 다른 사용자의 데이터, 데이터 사용자가 볼 수 있는 데이터와 볼 수 없는 데이터 간의 차별화를 의미할 수 있습니다.

Insecure Storage: S3 Full Anonymous Access

Java/JSP

Abstract

응용 프로그램은 AWS S3 버킷 또는 개체에 대한 전체 익명 액세스 권한을 부여합니다.

Explanation

버킷이나 개체에 대한 전체 익명 액세스 권한을 부여하면 공격자가 콘텐트를 읽거나 악성 콘텐트로 바꿀 수 있습니다.

예제 1: 다음 코드는 foo 버킷에 대한 전체 익명 액세스 권한을 부여하는 Access Control Policy를 설정합니다.


    GetBucketAclRequest bucketAclReq = GetBucketAclRequest.builder().bucket("foo").build();
    GetBucketAclResponse getAclRes = s3.getBucketAcl(bucketAclReq);
    List<Grant> grants = getAclRes.grants();

    Grantee allusers = Grantee.builder().uri("http://acs.amazonaws.com/groups/global/AllUsers").build();
    Permission fc_permission = Permission.fromValue("FullControl");
    Grant grant = Grant.builder().grantee(allusers).permission(fc_permission).build();
    grants.add(grant);

    AccessControlPolicy acl = AccessControlPolicy.builder().grants(grants).build();
