# Authorization Contexts

There are also times where you need to validate custom conditions and block access to certain areas. This way, you can implement your own custom security logic and leverage **cbSecurity** for blockage. You will accomplish this via the `secureWhen()` method.  If the `context` evaluates to `true` then it will throw a `NotAuthorized` exception for you.

{% hint style="info" %}
Remember, if the `context` is TRUE, then it throws the exception.
{% endhint %}

```javascript
secureWhen( context, [errorMessage] )
```

The `context` can be a closure/lambda/udf or a boolean evaluation:

```javascript
// Using as a closure/lambda
cbSecurity.secureWhen( ( user ) => !user.isConfirmed() )
cbSecurity.secureWhen( ( user ) => !oEntry.canPublish( user ) )

// Using a boolean evaluation
cbSecurity.secureWhen( cbSecurity.none( "AUTHOR_ADMIN" ) && !cbSecurity.sameUser( oAuthor )  )
cbSecurity.whenNone( "AUTHOR_ADMIN", ( user ) => relocate() );
```

The closure/udf will receive the currently authenticated user as the first argument.

```javascript
( user ) => {}
function( user );
```

You can also use the `message` argument to send your own message to the exception that's throw.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://coldbox-security.ortusbooks.com/usage/cbsecurity-model/authorization-contexts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
