The Security Component creates an easy way to integrate tighter security in your application. It provides methods for various tasks like:
- Restricting which HTTP methods your application accepts.
- Form tampering protection
- Requiring that SSL be used.
- Limiting cross controller communication.

configsource public
config( string|array|null $key null , mixed|null $value null , boolean $merge true )Usage
Reading the whole config:
$this->config();
Reading a specific value:
$this->config('key');
Reading a nested value:
$this->config('some.nested.key');
Setting a specific value:
$this->config('key', $value);
Setting a nested value:
$this->config('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);
Parameters
- 
     string|array|null $keyoptional null
- The key to get/set, or a complete array of configs.
- 
     mixed|null $valueoptional null
- The value to set.
- 
     boolean $mergeoptional true
- Whether to recursively merge or overwrite existing config, defaults to true.
Returns
mixedConfig value being read, or the object itself on write operations.
Throws
Cake\Core\Exception\ExceptionWhen trying to set a key that is invalid.
configShallowsource public
configShallow( string|array $key , mixed|null $value null )Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->config('key', $value);

Default config
- blackHoleCallback- The controller method that will be called if this request is black-hole'd.
- requireSecure- List of actions that require an SSL-secured connection.
- requireAuth- List of actions that require a valid authentication key.
- allowedControllers- Controllers from which actions of the current controller are allowed to receive requests.
- allowedActions- Actions from which actions of the current controller are allowed to receive requests.

- validatePost- Whether to validate POST data. Set to false to disable for data coming from 3rd party services, etc.
