Best Practices for Framework Security

Regardless of which framework you use, certain practices improve security across the board. First, stay updated with the latest framework versions, as security fixes are regularly released. Each framework's changelog highlights security updates, and staying current ensures you benefit from the latest protections. Set up automated dependency updates for your framework and audit warnings about security vulnerabilities in your dependencies.

Implement Content Security Policy headers even when using frameworks with built-in XSS protection. CSP provides defense-in-depth, catching vulnerabilities that might slip through framework protections. Modern frameworks work well with CSP, and many provide tooling to generate CSP-compliant builds. Use nonces or hashes for any inline scripts required by your framework, and avoid 'unsafe-inline' directives that weaken CSP's protection.

Regular security audits should include framework-specific checks. Look for uses of dangerous features like dangerouslySetInnerHTML, v-html, or bypassSecurityTrustHtml. Search for direct DOM manipulation that might bypass framework protections. Automated tools can help identify some of these patterns, but manual code review remains essential. Train your team on framework-specific security features and dangerous patterns. Many vulnerabilities come from developers not understanding their framework's security model.
