ZAP Scanning Report

Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement or distribution of malware. CSP provides a set of standard HTTP headers that allow website owners to declare approved sources of content that browsers should be allowed to load on that page — covered types are JavaScript, CSS, HTML frames, fonts, images and embeddable objects such as Java applets, ActiveX, audio and video files.

Ensure that your web server, application server, load balancer, etc. is configured to set the Content-Security-Policy header.

The response contents are not storable by caching components such as proxy servers. If the response does not contain sensitive, personal or user-specific information, it may benefit from being stored and cached, to improve performance.

The content may be marked as storable by ensuring that the following conditions are satisfied:

The request method must be understood by the cache and defined as being cacheable ("GET", "HEAD", and "POST" are currently defined as cacheable)

The response status code must be understood by the cache (one of the 1XX, 2XX, 3XX, 4XX, or 5XX response classes are generally understood)

The "no-store" cache directive must not appear in the request or response header fields

For caching by "shared" caches such as "proxy" caches, the "private" response directive must not appear in the response

For caching by "shared" caches such as "proxy" caches, the "Authorization" header field must not appear in the request, unless the response explicitly allows it (using one of the "must-revalidate", "public", or "s-maxage" Cache-Control response directives)

In addition to the conditions above, at least one of the following conditions must also be satisfied by the response:

It must contain an "Expires" header field

It must contain a "max-age" response directive

For "shared" caches such as "proxy" caches, it must contain a "s-maxage" response directive

It must contain a "Cache Control Extension" that allows it to be cached

It must have a status code that is defined as cacheable by default (200, 203, 204, 206, 300, 301, 404, 405, 410, 414, 501).
