X-Frame-Options HTTP header field is used for prevention against clickjacking attacks. Is it possible to insert X-Frame-Options into every HTTP response?
for Apache web server use mod_headers :
Apache mod_headers
and add "Header always append X-Frame-Options SAMEORIGIN".
There are three settings for X-Frame-Options:
SAMEORIGIN: This setting will allow page to be displayed in frame on the same origin as the page itself.
DENY: This setting will prevent a page displaying in a frame or iframe.
ALLOW-FROM uri: This setting will allow page to be displayed only on the specified origin.

How do you do this? I want only one other website to be able to load my main website in an iFrame but nothing is working.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/frame-ancestors
Apparently as I understand it the protocol you set in .htaccess is this
So far I've tried:
1.
Header set Content-Security-Policy "frame-ancestors 'self' https://example.subdomain.co;"
2.
Header always set Content-Security-Policy "frame-ancestors 'self' 'https://example.subdomain.co';"
3.
Header set Content-Security-Policy "frame-ancestors 'self' 'https://example.subdomain.co';"
None of these work. When I try to load an iframe of example.com inside https://example.subdomain.co I get the following error:
Refused to display 'https://example.com/' in a frame because it set
'X-Frame-Options' to 'sameorigin'.
And then I get more confused because apparently you can only do DENY and SAMEORIGIN with this.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options
The X-Frame-Options HTTP response header can be used to indicate
whether or not a browser should be allowed to render a page in a
<frame>, <iframe>, <embed> or <object>. Sites can use this to avoid
click-jacking attacks, by ensuring that their content is not embedded into other sites.
The added security is provided only if the user accessing the document
is using a browser that supports X-Frame-Options.
The one I would have wanted is ALLOW FROM but
ALLOW-FROM uri This is an obsolete directive that no longer works in
modern browsers. Don't use it. In supporting legacy browsers, a page
can be displayed in a frame only on the specified origin uri. Note
that in the legacy Firefox implementation this still suffered from the
same problem as SAMEORIGIN did — it doesn't check the frame ancestors
to see if they are in the same origin. The Content-Security-Policy
HTTP header has a frame-ancestors directive which you can use instead.
It's deprecated and it doesn't work.
Refused to display in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'
This answer doesn't help because they don't talk about what I want to do, they just explain what it is.
How to set 'X-Frame-Options' on iframe?
Again, not helpful because it's explaining to OP that the header is set on the website in the iframe source.
Is there a way to set it X-Frame-Options for frame-ancestors somehow to make this work so that I can load an iframe of my website on one other specific website? Or is this not possible?
When you set frame-ancestors correctly all browsers that understand it will disregard X-Frame-Options. This means that you can set both headers and use ALLOW-FROM as you will then server X-Frame-Options to IE and frame-ancestors to other browsers.
Have you checked if your Content-Security-Policy is present as a response header? Your first version is the most correct one, but you can drop the scheme as such: "frame-ancestors 'self' example.subdomain.co;", there should not be any single quotes around hosts in sources.
I am sorting out a website that will be getting pen-tested soon, we've have been asked to add the X-Frame-Options header to our server configuration. When adding the following header it gives me an error message in the console.log where we are using iframes
-- nginx header --
add_header 'X-Frame-Options' "SAMEORIGIN";
-- Error --
`Refused to display 'https://api.domain.com/' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
Obviously I understand the security reasons for this header but our website has an iframe that we simply cannot change & it is on a different domain e.g oldapp.domain.com rather than api.domain.com.
I would have used the ALLOW-FROM uri directive to allow from this other domain, but this directive is no longer recommended, is there an alternative to ALLOW-FROM uri that will enable me to simply add a domain that can be allowed to display iframe content?
For all browsers except some older ones (like IE) you should use Content-Security-Policy with the frame-ancestors directive instead. With CSP frame-ancestors you can use wildcards *.domain.com or multiple sources "oldapp.domain.com api.domain.com www.domain.com".
X-Frame-Options ALLOW-FROM only accepts one uri, you will likely have to dynamically set the uri from a list of allowed hostnames based on the incoming request. Alternatively you can set the value to SAMEORIGIN if you don't need to fully support IE and other outdated browsers as X-Frame-Options will be disregarded if CSP frame-ancestors is present.
I have a Lotus Notes web application which is been loaded in to another web application, after we upgraded to domino from 9.0.1 to Domino V10.0.4 the application fails to load in this portal, the application can be accessed individually in browser but while loading in another application it fails with error
Load denied by X-Frame-Options: http://achme.com/achme.NSF/frameset?readform does not permit cross-origin framing.
any hint on fixing the error
enter image description here
It seems that your Domino- server has a header value for X-Frame-Options set.
This can either be done with a Website- Rule of type "HTTP response headers" that defines the header in the domino directory:
X-Frame-Options: SAMEORIGIN
Possible values:
X-Frame-Options: deny
X-Frame-Options: sameorigin
X-Frame-Options: allow-from https://example.com/
Or it is set via notes.ini Entry:
HTTPAdditionalRespHeader=X-Frame-Options: SAMEORIGIN
Check your domino directory and the notes.ini for the setting and set it to something more relaxed if you need the page to be loaded in an iframe.
Do you happen to have changed the FQDN of your Domino server when upgrading? That might be a reason why the same setting worked in Domino 9 (old hostname) and does not work for the new server (new hostname).
After an windows update on our windows web server IIS 8 it, iframe of the hosted sharepoint 2013 stopped working from an external domain.
The server seems to force X-FRAME-OPTIONS SAMEORIGIN. This value is not set in web.config or in IIS Manager under HTTP Response Header.
I've tried to add a HTTP Response header in both IIS Manager and in web.config but it doesnt help.
If i dont add anything i get this error:
Refused to display 'http://SP-SITE' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
When i add the X-FRAME-OPTIONS ALLOW-FROM http://Other-url i get this error:
Refused to display 'http://SP-SITE' in a frame because it set multiple 'X-Frame-Options' headers with conflicting values ('SAMEORIGIN, ALLOW-FROM http://Other-URL, ALLOW-FROM http://Other-URL'). Falling back to 'deny'.
Does anyone know how i should find where the SAMEORIGIN value is set or how to override it or change it?
I want to block my site in the <iframe> tag. On research I found that to do so, I need to set the header as 'x-frame-options' to 'SAMEORIGIN'.
Tried setting the meta tag as
<meta http-equiv="X-Frame-Options" content="deny">
But this method is outdated since April 2016.
When I am trying to search it is giving me the result for httpClient.
But I want the same when Someone hit my url through .
Do I need to set the header through node or need to do some changes in angular.json
My site is working on node server with URL http://localhost:4200/.
You cannot do it on angular side, only on server side.
I think you can use this npm package:
https://www.npmjs.com/package/x-frame-options
If you are using any webserver like Nginx, Apache HTTP Server
example for how to use in Nginx
add_header X-Frame-Options "SAMEORIGIN";
in global scope, or location scope.
Better to do in location scope. Because, as soon as you add some header in location scope, the global scope will not reflect
Additional
You can take care of more things using the header like cross-site scripting
add_header X-XSS-Protection "1; mode=block";
Even though nowadays browsers are helping to reduce cross-site scripting. More detail description in here
