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. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/jeremylongshore) — claim your Tome and manage your conversions.
