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.

Cross-Site Scripting: Untrusted HTML Downloads

Abstract
noopen으로 설정되는 X-Download-Options 헤더를 비활성화하면 다운로드된 HTML 페이지가 이를 제공하는 사이트의 보안 컨텍스트에서 실행됩니다.
Explanation
사이트가 사용자에 대한 다운로드를 제공할 수 있어야 하는 경우 이를 여는 옵션은 브라우저에서 실행되는 모든 제공된 파일이 사이트와 동일한 보안 컨텍스트에서 현재 브라우저에서 열릴 수 있음을 의미합니다.
공격자가 다운로드되는 파일을 조작할 수 있는 경우 브라우저에서 Cross-Site Scripting 공격 역할로 실행되는 HTML 또는 스크립트를 삽입할 수 있어 현재 세션에서 정보를 훔치거나 조작할 수 있습니다.

예제 1: 다음 예제에서는 브라우저에서 실행되는 제공된 다운로드에 대한 보호를 명시적으로 비활성화합니다.


var express = require('express');
var app = express();
var helmet = require('helmet');

app.use(helmet({
ieNoOpen: false
}));
