Most pentest vendors are just checking a box to see if exists. Yes, in current versions of Chrome you will get an error such as the following: This is not supported, further the Content-Security-Policy-Report-Only header cannot be used in a meta tag either. The CSP policy only applies to content found after the meta tag is processed, so you should keep it towards the top of your document, or at least before any dynamically generated content. Content-Security-Policy: default-src 'self'; img-src 'self' cdn.example.com; In this example CSP policy you find two CSP directives: default-src and img-src. Providing every legitimate workload with a trusted execution environment for hardware-isolated protection of data in use, scaled to fit workloads of varying sizes. Why don't we know exactly where the Chinese rocket will fall? Should we burninate the [variations] tag? Intel delivers hardware platforms with protections against common and emerging software attacks, which increases efficiency and preserves performance. This solution works well with ASP.NET WebForms as it still allows inline (no need to extract everything to separate js files) as well as eval's. Content Security Policy A lack of a CSP policy should not be considered a vulnerability. Intels products and software are intended only to be used in applications that do not cause or contribute to a violation of an internationally recognized human right. The meta support is handy when you can't set a HTTP response header, but in most cases using a HTTP response header is a stronger approach. You won't be able to include external scripts from CDNs and similar. The CSP policy only applies to content found after the meta tag is processed, so you should keep it towards the top of your document, or at least before any dynamically generated content. When a user visits a page served over HTTPS, their connection with the web server is encrypted with TLS and is therefore safeguarded from most sniffers and man-in-the-middle attacks.
