The headers are not recognized by mozilla observatory. Any ideas?
add_header Content-Security-Policy: "frame-ancestors 'none'";
add_header X-Frame-Options: DENY;
Lose the : for a start.
It may not be necessary but I escape my ' instead of mixing and matching " and '.
Mine looks like this and works:
add_header Content-Security-Policy 'default-src \'self\' *.example.com; report-uri ....';

I wish you all a good day and a nice start in the Weekend :)
I set the next Headers in htaccess-file:
# Security Headers
<IfModule mod_headers.c>
- Header set Strict-Transport-Security "max-age=31536000" env=HTTPS
- Header set X-Permitted-Cross-Domain-Policies "none"
- Header set X-XSS-Protection "1; mode=block"
- Header set X-Frame-Options "deny"
- Header set X-Content-Type-Options "nosniff"
- Header always set Strict-Transport-Security "max-age=63072000; includeSubDomains"
- # Header set Content-Security-Policy ...
- Header set Referrer-Policy "no-referrer"
- Header set Feature-Policy "geolocation 'self'; vibrate 'none'"
</IfModule>
but when i scan my Website on "securityheader" it shows all the headers in red color. It means the website is not secure.
I would be so thankful, if someone likes/can show me the error?
Thank you and
Best regards
I want to ask how to set X-Frame-Options and Content Security Policy on netlify. As I have static website and its deployment server is netlify and I don't have any configuration file(netlify.toml). So, where can I set X-frame-Options and Content Security Policy.
Save a plain text file called _headers to the publish directory of your site (see details and syntax). For instance:
# a path:
/templates/index.html
# headers for that path:
X-Frame-Options: SAMEORIGIN
Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline';
# any other paths:
/*
X-Frame-Options: DENY
Content-Security-Policy: default-src 'self'
Also you can use specific CSP packages for Netlify. Generally they do the same - add headers into _headers file, but some of they do calculate hashes for scripts.
I'm running a NodeJS App on NGINX Web Server. I'm able to access all the URLs in my app via iframe on other websites.
Here is my NGINX conf:
proxy_hide_header X-Frame-Options;
How do I restrict the iframe to allow only 1 URL instead of all the URLs?
Also, how do I allow only a few domains to access via iframe?
Can it be done via NGINX or should it be handled via NodeJS code?
It can be done via both NGINX conf and nodejs.
For NGINX conf, please use both X-Frame-Options and Content Security Policy (frame-ancestors)
add_header Content-Security-Policy "frame-ancestors domain1 domain2 domain3"; -> it's for modern browsers
add_header X-Frame-Options "ALLOW-FROM domain1 domain2 domain3"; -> it's for older browsers
To get more details: X-Frame-Options Content-Security-Policy
It can be done by both nginx or nodejs. If you'd prefer nginx, you should use it within a location block like:
server {
location / {
add_header Content-Security-Policy "frame-ancestors 'none'";
add_header X-Frame-Options "DENY";
}
location /iframing_is_allowed {
add_header Content-Security-Policy "frame-ancestors http: https:";
proxy_hide_header X-Frame-Options;
}
}
Otherwise, if you'd prefer nodejs, you should set these headers from your JS code in the corresponding endpoints.
If you looking for what options you have, please consult to X-Frame-Options and Content-Security-Policy docs, as Thang Duc pointed.
I used this in
Ubuntu 14.04
add_header X-Frame-Options "allow-from https://*.sample.com http://*.sample.com";
add_header Content-Security-Policy "frame-ancestors https://*.sample.com http://*.sample.com";
And it worked like a charm.
I added the
<meta http-equiv="X-Frame-Options" content="deny">
in header.tpl file ,but it not working and throws an error.
X-Frame-Options may only be set via an HTTP header sent along with a document. It may not be set inside .
And I also added the
Header always append X-Frame-Options SAMEORIGIN
line in .htaccess file. But this is also not working.
Then how can I prevent Clickjacking on my Website?
For references : Clickjacking Defense Cheat Sheet | OWASP and X-Frame-Options - HTTP
I suggest you to edit the .htaccess in your PrestaShop root folder installation and, just before the lines identified by "# ~~start~~ Do not remove..." add the following block:
# Extra Security Headers
<IfModule mod_headers.c>
Header set Content-Security-Policy "default-src 'unsafe-inline' 'unsafe-eval' 'self' *.googleapis.com *.gstatic.com;"
Header set X-XSS-Protection "1; mode=block"
Header always append X-Frame-Options SAMEORIGIN
Header set X-Content-Type-Options nosniff
Header set Strict-Transport-Security: max-age=63072000; includeSubDomains; preload
</IfModule>
This will provide protection against:
clickjacking - content sniffing - XSS attacks
We are moving our Federal government website to https-only. We have received complaints from sites we link to that our referrers have disappeared, when those sites use only http. This is because https->http downgrade, by default, hides the referrer.
We are trying to use the HTTP request header Referrer-Policy: origin-when-cross-origin, but it doesn't seem to work. However, putting <meta name='referrer' content='origin-when-cross-origin'> indeed provides the correct behavior for most browsers.
We are setting the header:
<pre>
$ curl -sI https://www.ncbi.nlm.nih.gov/corecgi/tests/testref.cgi
HTTP/1.1 200 OK
Date: Fri, 04 Nov 2016 20:53:38 GMT
Server: Apache
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
Content-Security-Policy: upgrade-insecure-requests
Referrer-Policy: origin-when-cross-origin
Content-Security-Policy-Report-Only: default-src https:; script-src https: 'unsafe-inline' 'unsafe-eval'; font-src https: data:; img-src https: data:; style-src https: 'unsafe-inline'; report-uri https://www.ncbi.nlm.nih.gov/corecgi/csp/csp.cgi
Referrer-Policy: origin-when-cross-origin
Access-Control-Allow-Methods: POST, GET, PUT, OPTIONS, PATCH, DELETE
Access-Control-Allow-Origin:
Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: X-Accept-Charset,X-Accept,Content-Type,X-Requested-With,NCBI-SID,NCBI-PHID
Content-Type: text/html
Vary: Accept-Encoding
X-UA-Compatible: IE=Edge
X-XSS-Protection: 1; mode=block
</pre>
But that header doesn't work:
Try this: https://www.ncbi.nlm.nih.gov/corecgi/tests/testref.cgi
Notice that the https->http downgrade link sends a blank header
Yet it the <meta> element gives the desired behavior:
https://www.ncbi.nlm.nih.gov/corecgi/tests/testref.cgi?meta=true
Has anyone else had, and fixed, this problem?
It looks like Chrome is about to, but doesn't quite yet, support the Referrer-Policy header:
https://bugs.chromium.org/p/chromium/issues/detail?id=619228
https://www.chromestatus.com/feature/5639972996513792
It will be available in Chrome 56 stable. It's been behind a flag since Chrome 53, so you can run Chrome with --enable-experimental-web-platform-features to try it out there.
Referrer-Policy header support will ship in Firefox 50:
