Understanding Content Security Policy (CSP)
A Content Security Policy (CSP) is an HTTP security header that tells browsers which sources of content (scripts, styles, images, etc.) are allowed to load on your pages. It serves as a whitelist that prevents unauthorized code injection.
CSP is a powerful defense against cross-site scripting (XSS) attacks, clickjacking, and other code injection vulnerabilities. By specifying exactly which domains can serve content on your pages, you prevent malicious scripts from executing.
Why Content Security Policy (CSP) Matters for Shopify Stores
A properly configured CSP can prevent malicious scripts from running on your Shopify store, protecting customer data from theft. It's particularly important if you use custom code or third-party apps that could introduce vulnerabilities.
Frequently Asked Questions
Frequently Asked Questions
Does Shopify implement CSP?
Shopify implements some CSP protections by default. However, custom themes and apps may require additional CSP configuration to maintain security.
Can CSP break my store functionality?
An overly restrictive CSP can block legitimate resources. Start with a report-only policy to identify issues before enforcing, and make sure to whitelist all legitimate third-party services your store uses.
