Your page could be put in a `<frame>` or `<iframe>` without your consent. This can result in clickjacking attacks, among other things. Clickjacking is a technique of tricking a user into interacting with a page different from what the user thinks it is. This can be obtained executing your page in a malicious context, by mean of iframing. In that context a hacker can put a hidden layer over your page. Hidden buttons can be used to run bad scripts. This middleware sets the X-Frame-Options header. It restricts who can put your site in a frame. It has three modes: DENY, SAMEORIGIN, and ALLOW-FROM.
|

|
|
|
|||
|
|
We don’t need our app to be framed.
|
|||
|
|
|
|||
|
|
# --instructions--
|
|||
|
|
|
|||
|
|
Use `helmet.frameguard()` passing with the configuration object `{action: 'deny'}`.

# --hints--
|
|||
|
|
|
|||
|
|
helmet.frameguard() middleware should be mounted correctly
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
(getUserInput) =>
|
|||
|
|
$.get(getUserInput('url') + '/_api/app-info').then(
|
|||
|
|
(data) => {
|
|||
|
|
assert.include(
|
|||
|
|
data.appStack,
|
|||
|
|
'frameguard',
|
|||
|
|
'helmet.frameguard() middleware is not mounted correctly'
|
|||
|
|
);
|
|||
|
|
},
|
|||
|
|
(xhr) => {
|
|||
|
|
throw new Error(xhr.responseText);
|
|||
|
|
}
|
|||
|
|
);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
helmet.frameguard() 'action' should be set to 'DENY'
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
(getUserInput) =>
|
|||
|
|
$.get(getUserInput('url') + '/_api/app-info').then(
|
|||
|
|
(data) => {
|
|||
|
|
assert.property(data.headers, 'x-frame-options');
|
|||
|
|
assert.equal(data.headers['x-frame-options'], 'DENY');
|
|||
|
|
},
|
|||
|
|
(xhr) => {
|
|||
|
|
throw new Error(xhr.responseText);
|
|||
|
|
}
|
|||
|
|
);
|
|||
|

```
