界: Encapsulation

封装即绘制强边界。在 Web 浏览器中，这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上，这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据，或者区分允许用户查看的数据和不允许用户查看的数据。

Cross-Site Scripting: Untrusted HTML Downloads

JavaScript/TypeScript

Abstract

禁用要设置为 noopen 的 X-Download-Options 标头后，下载的 HTML 页面可以在提供这些页面的站点的安全上下文中运行。

Explanation

当站点需要能够为用户提供下载时，打开下载文件的选项意味着，所提供的在浏览器中运行的任何文件均可以在与站点位于相同安全上下文的当前浏览器中打开。
如果攻击者能够操纵下载的文件，则他们可以插入在浏览器中运行的 HTML 或脚本作为跨站脚本攻击，从而窃取或操纵当前会话中的信息。

示例 1：以下示例明确禁用了对运行于浏览器中的提供的下载的保护：


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

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