Secure Headers Csp Builder

What it does

The secure-headers-csp-builder skill generates secure HTTP headers, specifically Content Security Policy (CSP) directives. It helps protect web applications from cross-site scripting (XSS) and other attacks by defining a whitelist of allowed resources. The skill can create CSP policies based on your application's needs and generate the necessary header configurations.

When to use it

• Securing a new website: Generate initial CSP headers to enhance security posture right from deployment.
• Updating existing site security: Refactor or improve current CSP rules for better protection against evolving threats.
• Troubleshooting CSP errors: Create and test different CSP configurations to identify and resolve blocking issues.
• Automating security hardening: Integrate the skill into a CI/CD pipeline to automatically generate secure headers.

Key capabilities

• Generates Content Security Policy (CSP) directives.
• Creates secure HTTP header configurations.
• Helps protect against XSS attacks.

Example prompts

• "Generate a CSP policy for a website that loads scripts from cdn.example.com and images from images.example.com."
• "Create a strict CSP policy with report-uri to monitor violations."
• "What is the default CSP policy?"

Tips & gotchas

The generated CSP policies need careful review and testing before deployment, as overly restrictive rules can break website functionality. Ensure you understand the implications of each directive before implementing it in production.
