Content-Security-Policy (CSP) Checker
My Content-Security-Policy (CSP) Checker helps you analyze and optimize the effectiveness of your Content-Security-Policy. CSP is an important security feature that helps prevent Cross-Site Scripting (XSS) attacks, data injection, and other breaches by determining which resources can and cannot be loaded on your website.
What is Content Security Policy (CSP)?
Content Security Policy (CSP) is a security mechanism that you can include in your Web site’s HTTP headers to control which scripts, stylesheets, and other resources are allowed to execute. This provides protection against threats such as XSS and data injection by creating a “whitelist” of trusted sources.
Why use a CSP Checker?
- Increased security: Make sure your CSP works effectively and protects your website from attacks such as XSS.
- Troubleshooting: Identify problems or errors in your current CSP implementation that could weaken security.
- Optimization: Improve your CSP by receiving recommendations on how to better adapt your policies to your site’s security needs.
- Prevent Content Delivery Issues: Make sure your policy does not impose unintended restrictions that block legitimate content.
How does the CSP Checker work?
- Enter your URL or CSP: Type or paste the URL of the website you want to check, or manually enter your CSP header.
- Automatic check: The tool scans your website and analyzes the current CSP configuration.
- Receive Results: Receive a detailed report that identifies problems and possible improvements.
- Take Action: Apply the recommendations to strengthen your CSP and optimize website security.
What does this tool check for?
- Policy effectiveness: verifies that your CSP headers are properly configured and protective against attacks.
- Syntax errors: Identifies any errors in the syntax of your CSP that may limit operation.
- Source validation: Verifies that all external sources (such as scripts, stylesheets, etc.) that your Web site loads are allowed within your CSP.
With my CSP Checker, you can easily and quickly check that your Content Security Policy is set up correctly and functioning optimally. By using this tool regularly, you can better protect your website from malicious attacks and ensure that your security policies are consistent and effective.
