JavaScript Security: Fortify Your Code In Motion

JavaScript Security: Fortify Your Code In Motion

JavaScript, a powerful programming language, is chiefly employed in web application development, enhancing features like form submission, validation, and intelligent user interaction. Embedded in web pages, JavaScript functions utilize the Document Object Model (DOM) for action execution. Its versatility extends to Android applications, facilitated by various cross-platform tools, and is even utilized for server-side programming.

How to secure Javascript

Different tools and techniques are available to secure JavaScript web pages and applications. The goal for developers and stakeholders is always to write secure and clean code, enhancing the security and privacy of users. Some of the techniques to secure the JavaScript programming language are as follows:

• SAST: Static application security testing (SAST) is a method of testing and analyzing the source code or compiled version of the application without executing the program. SAST enables developers to promptly detect errors, enhance code quality, and fortify web pages and applications against potential vulnerabilities and security threats. It focuses on static testing during the code development phase.

• Code Obfuscation: Examining the application code is the first step when conducting reconnaissance and preparing an attack or searching for vulnerabilities, as it is a rich source of information. JavaScript is delivered to the user, containing all the logic and design of the website; therefore, it is essential to be protected. Obfuscation adds a protective layer to the JavaScript code; it is used to obscure or make the code more difficult to understand while preserving its functionality. Although, it has very strong points like code protection, reducing code size, and preserving intellectual property, it is not a security method by itself.

• Session Management: Attackers can manipulate authentication methods by impersonating as an authentic user and perform different attack actions. This can be secure by using time-based session tokens and session token must be recreated after each login. Secondly, HTTPS protocol for the transmission of session tokens. 

• Strict Mode: Strict mode must be used to perform code optimization by removing errors and showing those errors during code development. Hence, removing code errors that might result in code development related vulnerabilities. 

• Encryption: Encryption significantly enhances the security of JavaScript code. All data must be encrypted during transmission, and a secure mechanism, such as SSL, TLS, and HTTPS, must be employed for the transmission of critical data. Additionally, unnecessary data should be eliminated to secure sensitive information.

• Cookies: Cookies are data chunks stored in the user’s web browser during web surfing. These are used to track and save user’s session data. Cookies must be accessed only via HTTPS and access must be permitted through JavaScript. Secondly, cookies must be accessed through proper domains and cookies must expire after a specific time. 

  

Codesealer Solution 

Protect your Javascript and Intellectual property from prying eyes and manipulation. The Codesealer Javascript protection takes over all Javascript delivery, applying state-of-the-art authenticated encryption to make your Javascript code invisible and tamper-proof, delivered via a secured and confirmed channel only when safe to do so. 

 With Codesealers Code protection, attackers can no longer easily analyze your client-side business logic and find exploits. Your development team can rest easy knowing Codesealer will be a safety net, hiding any weaknesses that accidentally make it to production. 

Codesealer provides a novel layer of security for Web Applications which completely changes the attacker’s landscape. When Codesealer is deployed, all an attacker sees is encrypted scripts and the highly secure and tamper resistant Application Code. This makes it extremely difficult to reverse engineer the application, leaving the attacker essentially blind, unable to even begin looking for exploits.   

The JavaScript protection mechanisms undergo frequent compatibility tests to ensure they remain platform-agnostic, functioning seamlessly across all browsers, JavaScript frameworks, and libraries. Our foremost priority is to enhance the security posture of your company’s web applications without imposing any technology limitations on your development team or end-users.
