Many web developers consider security a low priority. Security is frequently relegated to the end of the software development life cycle, as little more than an afterthought. Sometimes, software security is neglected entirely, resulting in applications rife with common vulnerabilities. Because such bugs might manifest only under conditions present during an attack, they can be hard to detect prior to such events without knowledge of how the exploitation process works. Using a web application built with jQuery Mobile, PHP, and MySQL, this tutorial shows how many types of vulnerabilities occur along with common methods of exploitation and, most importantly, their respective countermeasures.
This article present techniques to help prevent the gaming of your MySQL-PHP Website. Some of them rely on shutting down scripts; others try to find the humans who are manually executing this behavior.
