Kingdom: Code Quality

Poor code quality leads to unpredictable behavior. From a user's perspective that often manifests itself as poor usability. For an attacker it provides an opportunity to stress the system in unexpected ways.

ASP.NET Bad Practices: Unminified Code

Abstract
Unminified JavaScript has been included in this file. Microsoft recommends that minified versions of JavaScript libraries should be included for performance reasons.
Explanation
Minification improves page load times for applications that include JavaScript files by reducing the file size. Minification refers to the process of removing unnecessary whitespace, comments, semicolons, braces, shortening the names of local variables and removing unreachable code.

Example 1: The following ASPX code includes the unminified version of Microsoft's jQuery library:


...
<script src="http://applicationserver.application.com/lib/jquery/jquery-1.4.2.js" type="text/javascript"></script>
