Security: Missing Security Headers
Description
It's best practice in web application security to set some headers that increase the security level of the application. Basically, the following headers should be set by default to increase the security of all deployments:
-
X-Frame-Options: deny: Prevents clickjacking attacks and other attack techniques against the application. More.... -
X-XSS-Protection: 1; mode=block: Increases the difficulty for exploitation of Cross Site Scripting attacks (XSS) in many browsers. More... -
X-Content-Type-Options: nosniff: Indicate that the browser doesn't tries to deduce a content type different from the Content-Type header. More...
Furthermore recommended, but difficult to implement effectively:
-
Content-Security-Policy: Whitelist possible resources and restricts JavaScript usage. Correctly implemented, this increases the difficulty for exploitation of Cross-site scripting attacks. More...
