Everything You Need to Know to Improve JavaScript Security – Security Boulevard

JavaScript is a great programming tool, but JavaScript security problems can cause significant damage to organizations and their customers. To help cybersecurity professionals and software developers better understand everything they need to know to improve JavaScript security, weve developed a free, comprehensive e-book, The Ultimate Guide to JavaScript Security. In it, we address the increasing number of threats and damaging attacks connected to JavaScript vulnerabilities, flaws, and open-source libraries. The guide highlights the fundamental risks associated with using JavaScript in an unprotected client-side environment, and what application security professionals and web application developers can do to better protect their websites and customers.

Among professional developers, for the last nine years in a row, JavaScript has been cited as the most popular programming language, according to the 2021 Stack Overflow Developer Survey. This comes as no surprise. JavaScript is easy to learn and use, operates quickly within a browser, works well with other programming languages, reduces server load, and offers programmers the ability to create rich and engaging interfaces.

But JavaScript has one big problem: it is highly insecure, with threat actors increasingly using JavaScript to deliver attacks, often from open-source and third-party JavaScript libraries.

The power of JavaScript is evident across todays digital landscape. Almost 98% of all websites use JavaScript as the client-side programming language to add interactive behavior to webpages and to create web and mobile apps. Banking sites use it for customer forms; e-commerce sites depend on it heavily to support the user experience during the shopping and purchasing process; and businesses use it for advertising and analytics.

However, traditional perimeter security tools, like firewalls, dont secure the front end or client side of a web application. This means that any organization leveraging JavaScript on the client side is at much greater risk of attack from threats like Magecart, e-skimming, formjacking, and cross-site scripting.

The free, new e-book: The Ultimate Guide to JavaScript Security contains five primary sections that cover everything businesses, AppSec professionals, CISOs, and web developers need to know about JavaScript security:

Each of these sections addresses key issues related to JavaScript security from a client-side perspective and provides the reader with guidance on how to better protect customers and businesses.
