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。
Python Bad Practices: Leftover Debug Code
Abstract
调试代码可以在部署的 Web 应用程序中建立一些意想不到的入口点。
Explanation
在实践中，人们往往为了达到调试和测试代码的目的而输出某些变量的值，同时附带的还有一些本不应提供或保留在正式部署的应用系统中的代码。当这种类型的调试代码意外地留在应用程序中，应用程序可能会在无意间将其泄漏给攻击者。但并不是所有的调试指令都会泄漏敏感或私密信息。然而，调试语句的出现通常意味着附近的代码已被忽略，而且可能处在一种不受维护的状态。
