All network requests must occur over HTTPS to prevent man-in-the-middle tampering with JavaScript files or API payloads. Never assume that data from query parameters, headers, or form fields conforms to expected formats.
Secure Client-Side Storage: JavaScript Patterns for Safe Data Handling
This discipline involves writing code that resists injection attacks, prevents data leaks, and maintains integrity across diverse environments. Client-side code cannot be trusted, as attackers have full control over the runtime and network conditions.
Treating all user-generated content as hostile prevents the majority of injection vulnerabilities before they can execute. Understanding the Attack Surface To effectively secure JavaScript, you must first understand the vectors through which malicious actors attempt to breach your application.
