Claude-code-plugins-plus-skills Analyzing Security Headers

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

1. Receives URL: Claude receives a URL or domain name from the user.
2. Analyzes Headers: The plugin fetches the HTTP headers from the specified URL and analyzes them against security best practices.
3. 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:

1. Fetch the HTTP headers from example.com.
2. Analyze the headers for common security vulnerabilities.
3. 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:

1. Fetch the HTTP headers from mywebsite.net.
2. Analyze the headers for common security vulnerabilities.
3. 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.
