Overview
This skill allows Claude to automatically analyze a website's HTTP security headers and provide a comprehensive report. It identifies missing or misconfigured headers and offers actionable recommendations to improve security posture.
How It Works
- Receives URL: Claude receives a URL or domain name from the user.
- Analyzes Headers: The plugin fetches the HTTP headers from the specified URL and analyzes them against security best practices.
- Generates Report: The plugin generates a detailed report, including a security grade, score, and specific recommendations for missing or misconfigured headers.
When to Use This Skill
This skill activates when you need to:
- Analyze the security posture of a website.
- Identify missing or misconfigured HTTP security headers.
- Get recommendations for improving website security.
- Audit a website for compliance with security best practices.
Examples
Example 1: Security Audit
User request: "Analyze the security headers for example.com"
The skill will:
- Fetch the HTTP headers from example.com.
- Analyze the headers for common security vulnerabilities.
- Generate a report outlining the security grade, score, and any identified issues with recommendations.
Example 2: Quick Security Check
User request: "Check HTTP security for mywebsite.net"
The skill will:
- Fetch the HTTP headers from mywebsite.net.
- Analyze the headers for common security vulnerabilities.
- Generate a report outlining the security grade, score, and any identified issues with recommendations.
Best Practices
- Prioritize HSTS: Ensure HSTS is properly configured to prevent downgrade attacks.
- Implement CSP: Start with a strict Content Security Policy to mitigate XSS vulnerabilities.
- Regularly Scan: Schedule regular scans to identify new vulnerabilities and misconfigurations.
Integration
This skill can be used in conjunction with other security plugins to provide a more comprehensive security assessment. For example, it can be paired with a vulnerability scanner to identify both header-related and code-level vulnerabilities.
