Is Content-Security-Policy a header?

Content-Security-Policy is the name of a HTTP response header that modern browsers use to enhance the security of the document (or web page). The Content-Security-Policy header allows you to restrict which resources (such as JavaScript, CSS, Images, etc.) can be loaded, and the URLs that they can be loaded from.

Example CSP Header with Java

What is @secured in spring boot?

The @Secured annotation is used to specify a list of roles on a method. So, a user only can access that method if she has at least one of the specified roles.

What is Content-Security-Policy HTTP header?

The HTTP Content-Security-Policy response header allows web site administrators to control resources the user agent is allowed to load for a given page. With a few exceptions, policies mostly involve specifying server origins and script endpoints.

How does CSP header work?

CSPs protect against dangling markup attacks by restricting the page's origin of images to be loaded. The img-src 'self' directive only allows images to be loaded from the exact origin. The img-src <allowed-web-url> directive governs the page to load images from a specific domain.

Should CSP be meta tag or header?

The header is the most common and recommended. Applying CSP is as simple as setting 'Content-Security-Policy' or 'Content-Security-Policy-Report-Only' on the HTTP response. It's highly recommended to use the HTTP header over the meta tag.

What is Content-Security-Policy report only header?
