Secure Coding Practices in Node.js
Implement best practices to prevent common vulnerabilities like XSS, CSRF, and SQL injection in your Node.js code.
Why Secure Coding Matters
Welcome! In this lesson, we'll dive into critical secure coding practices for Node.js. Writing secure code is just as important as writing functional code.
Understanding and preventing common vulnerabilities protects your application and your users from malicious attacks.
- Data Breaches: Exposed sensitive information.
- Service Downtime: Attacks can crash your application.
- Reputation Damage: Loss of user trust.
Cross-Site Scripting (XSS)
Cross-Site Scripting (XSS) is a common web vulnerability where attackers inject malicious scripts (usually JavaScript) into web pages viewed by other users.
When a user's browser loads the affected page, the malicious script executes, potentially stealing cookies, session tokens, or altering page content.
- Reflected XSS: Script immediately executed from user input.
- Stored XSS: Malicious script saved in database, then served to users.
- DOM-based XSS: Vulnerability in client-side code modifying the DOM.
