# AWS::MediaLive::InputSecurityGroup
<a name="aws-resource-medialive-inputsecuritygroup"></a>

The AWS::MediaLive::InputSecurityGroup is a MediaLive resource type that creates an input security group.

A MediaLive input security group is associated with a MediaLive input. The input security group is an "allow list" of IP addresses that controls whether an external IP address can push content to the associated MediaLive input.

## Syntax
<a name="aws-resource-medialive-inputsecuritygroup-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON

## Return values
<a name="aws-resource-medialive-inputsecuritygroup-return-values"></a>

### Ref
<a name="aws-resource-medialive-inputsecuritygroup-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the name of the input security group.

For example: `{ "Ref": "myInputSecurityGroup" }`

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).

### Fn::GetAtt
<a name="aws-resource-medialive-inputsecuritygroup-return-values-fn--getatt"></a>

The `Fn::GetAtt` intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the `Fn::GetAtt` intrinsic function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html).

#### 
<a name="aws-resource-medialive-inputsecuritygroup-return-values-fn--getatt-fn--getatt"></a>

`Arn`  <a name="Arn-fn::getatt"></a>
