JavaScript Security Best Practices

Content-Security-Policy: default-src 'self'; script-src 'self' trusted-scripts.com;

Prevents all external scripts
Encrypts all script content
Controls which resources can be loaded
Content Security Policy (CSP) is a security feature that helps prevent various attacks, including XSS, by controlling which resources can be loaded and executed. This specific CSP header allows resources to be loaded only from the same origin ('self') and scripts from both same origin and trusted-scripts.com. It's a crucial security layer that helps mitigate the impact of content injection vulnerabilities.
Blocks all inline scripts
