How to Configure Your Website's CSP Policy for Convert Experiments

In the evolving landscape of web development and online security, Content Security Policy (CSP) has become a cornerstone in safeguarding websites against various types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. However, implementing CSP can sometimes inadvertently block legitimate scripts and tools that website owners wish to use, such as Convert Experiments for A/B testing and website optimization. To ensure that Convert Experiments runs smoothly on your site without compromising security, it's essential to properly configure your CSP. Here's a step-by-step guide on how to do just that.

Understanding CSP

Before diving into the configuration, let's briefly understand what CSP is. CSP is a security standard introduced to prevent certain types of attacks on web applications. It allows web developers to control which resources the browser is allowed to load for a given page by specifying directives in the website's headers.

Configuring CSP for Convert Experiments

To allow Convert Experiments to function correctly on your website while maintaining the security benefits of CSP, you need to whitelist specific domains in your CSP policy. This is particularly important for the `connect-src` directive, which controls which sources the browser can connect to via script interfaces.

Here are the domains you should whitelist in your CSP policy for Convert Experiments:

1. **`*.metrics.convertexperiments.com`**: This domain is used by Convert Experiments to collect metrics and data from experiments running on your site. Whitelisting this domain ensures that your A/B testing data is accurately captured and reported.

2. **`logs.convertexperiments.com`**: Convert Experiments uses this domain to log information and errors. Allowing access to this domain helps in debugging and maintaining the smooth operation of your experiments.

3. **`*.convertexperiments.com`**: Whitelisting this domain is a broader approach that covers all subdomains of `convertexperiments.com`, ensuring that any script or resource needed by Convert Experiments is allowed by your CSP.

#### Step-by-Step Guide to Updating Your CSP

1. **Locate Your CSP Header**: Your CSP is usually set in the HTTP header of your website's responses. Locate the header in your web server's configuration. This could be in `.htaccess`, `nginx.conf`, or your website's meta tags, depending on how your site is hosted.

2. **Modify the `connect-src` Directive**: Add the above-listed domains to the `connect-src` directive of your CSP. If you don't have a `connect-src` directive, you'll need to add one. The modified directive might look something like this:

```
connect-src 'self' *.metrics.convertexperiments.com logs.convertexperiments.com *.convertexperiments.com;
```

This line allows connections to your own domain ('self'), as well as the specified Convert Experiments domains.

3. **Test Your Configuration**: After updating your CSP, it's crucial to test your website to ensure that Convert Experiments scripts are loading correctly and that there are no CSP violation reports. Tools like Google Chrome's Developer Tools can help you identify any CSP issues.

4. **Deploy Changes**: Once you've confirmed that everything is working as expected, deploy the changes to your live site.

Conclusion

Configuring your CSP to allow Convert Experiments ensures that you can continue to optimize your website through A/B testing without sacrificing security. By carefully updating your CSP policy to include the necessary domains, you maintain the integrity of your site's security while leveraging the powerful insights and optimizations that Convert Experiments offers. Remember, the goal is to strike a balance between security and functionality, allowing your site to be both safe and high-performing.
