SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical need to secure web applications against common client-side attacks by auditing, generating, and fixing HTTP security headers, specifically focusing on Content-Security-Policy (CSP) and related directives.

Core Features & Use Cases

  • Audit Existing Headers: Analyze current security headers for vulnerabilities and overly permissive settings.
  • Generate CSP: Create a production-ready Content-Security-Policy tailored to your application's needs.
  • Fix Header Issues: Correct misconfigurations and implement best practices for headers like HSTS and X-Frame-Options.
  • Use Case: A developer needs to ensure their web application is protected against clickjacking and cross-site scripting (XSS) attacks by implementing a robust Content-Security-Policy.

Quick Start

Use the memstack-security-csp-headers skill to generate a secure Content-Security-Policy for my web application.

FAQPage Schema
How do I generate a Content-Security-Policy header for my web application?

To generate a Content-Security-Policy header, you audit your application's resource loading requirements and construct a tailored policy. This skill creates production-ready CSP configurations to protect against cross-site scripting and unsafe-inline vulnerabilities.

What's the best way to prevent clickjacking using X-Frame-Options?

The best way to prevent clickjacking is by configuring the X-Frame-Options or frame-ancestors CSP directive. This skill audits your current headers and fixes misconfigurations to ensure your web application cannot be maliciously framed.

How do I audit existing HTTP security headers for vulnerabilities?

You audit HTTP security headers by analyzing current configurations for overly permissive settings. This skill evaluates your headers against web security best practices and identifies vulnerabilities related to HSTS, CSP, and X-Frame-Options.

Does my web application need HSTS headers to be secure?

Your web application needs HSTS headers to enforce secure HTTPS connections and prevent protocol downgrade attacks. This skill helps you implement and fix HSTS configurations alongside other critical security headers like CSP.

How do I fix unsafe-eval and unsafe-inline CSP directives?

To fix unsafe-eval and unsafe-inline CSP directives, you must identify the scripts requiring them and refactor the code to use nonces or hashes. This skill analyzes your policy to correct misconfigurations and implement safer header practices.

When should I use Content-Security-Policy versus X-Frame-Options?

You use Content-Security-Policy for comprehensive client-side attack prevention and X-Frame-Options specifically for clickjacking protection. This skill audits and configures both, ensuring your web application applies the correct HTTP header combinations.
