A Content Security Policy (CSP) is a critical security feature that helps protect your website from various types of attacks, particularly cross-site scripting (XSS) and data injection attacks. It works by specifying which content sources are trusted, effectively controlling what resources can be loaded on your web page.
A CSP is implemented through HTTP headers or meta tags that instruct the browser which domains, subdomains, and types of resources are permitted to load. For example, you can specify that scripts should only load from your own domain, or that images can come from both your domain and a trusted third-party service.

Why You Should Be Careful When Modifying Your CSP
While the ability to modify your CSP offers great flexibility, it comes with significant responsibility:
Security Implications: Loosening your CSP can expose your application to security vulnerabilities. Each modification that makes your policy more permissive increases potential attack surfaces.
Functionality Risks: Be careful when editing your CSP as you can unintentionally affect your site functionality. Changes may prevent scripts, images, styles, or other resources from loading properly, causing parts of your website to break or behave unexpectedly.
Compliance Concerns: For regulated industries, modifying security policies might impact your compliance status with standards like PCI DSS, HIPAA, or GDPR.
Best Practices for CSP Modifications
When modifying your CSP in Kodaris:
Test thoroughly: Always test CSP changes in your test environment first or during non-business hours
Make incremental changes: Modify one directive at a time and verify functionality.
Document all changes: Keep a record of what was changed, when, and why.
Review regularly: Security requirements evolve; regularly review your CSP to ensure it remains appropriate.
