Shipping Secure Code
Security is a continuous process, not a checkbox. As web developers, we are the first line of defense for our users' data.
Content Security Policy (CSP)
A strong CSP can prevent 90% of XSS attacks by restricting where scripts can be loaded from. Set it up via HTTP headers or Meta tags.
Encryption at Rest and in Transit
Always use HTTPS. For sensitive data like API keys or PII, ensure they are encrypted using industry-standard algorithms (AES-256) before hitting the disk.
Sanitization
Never trust user input. Use libraries like DOMPurify for HTML and built-in ORM features to prevent injection attacks.
