Securing JavaScript Applications

Application Security

JavaScript is ubiquitous - it powers multitude of libraries, frameworks and many other applications. JavaScript is a very dynamic language - it allows you to create new variables and determine the type of variables at runtime, and create functions or replace the existing functions at any time.

Inherent Risks in JavaScript Applications

Consider the Cordova build process, the web and the native-container codes are packaged into distributable artifacts (APK or IPA). Both APK and IPA files are based on the zip file format and can easily be opened by any zip-compatible tool, thus exposing web code in clear text. Cordova warns that source-code is not secure and is vulnerable to reverse engineering.

Dynamic nature of JavaScript makes it vulnerable to tampering attacks, such as modifying the code to change application behavior or injecting malicious code. Given that JavaScript code is always deployed in source form, it’s highly vulnerable to attacks. Adversaries could use JavaScript API as attack gateway to expose applications and data on back-end servers.

JavaScript offers many benefits, including but not limited to - high degree of deployment flexibility and portability. However, the inherent risks in JavaScript applications expose the businesses to loss of brand, trust, IP, and revenue.
