Security Headers Configuration

What it does

This skill configures HTTP security headers to harden web applications against common attacks like Cross-Site Scripting (XSS) and Clickjacking. It automatically generates and applies the correct header values based on your specific application context and requirements.

When to use it

• Production Deployment: Immediately after launching a new website or API to establish a baseline security posture.
• Compliance Audits: Preparing infrastructure for security reviews that require evidence of implemented defense-in-depth strategies.
• Legacy Modernization: Updating older applications that lack native support for modern browser security directives.
• Third-Party Integration: Ensuring external services or embedded content adhere to strict security policies before they are exposed to users.

Key capabilities

• Generates standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
• Tailors header configurations dynamically based on the detected application type (e.g., SPA, API, static site).
• Validates current header settings to identify missing or misconfigured directives.
• Provides actionable recommendations for fixing identified security gaps without manual code editing.

Example prompts

• "Configure HTTP security headers for my React application hosted on Netlify to prevent XSS attacks."
• "Audit my existing server configuration and suggest the best security headers for a Python Flask API."
• "Generate a comprehensive list of security headers I should implement for an e-commerce site handling sensitive user data."

Tips & gotchas

Ensure your web server or framework supports the specific headers you are configuring, as some older environments may not recognize newer directives like Cross-Origin-Opener-Policy. Always test header implementation in a staging environment first to verify browser compatibility and ensure they do not inadvertently break legitimate functionality like iframe embedding for analytics.
