# CreateCacheSecurityGroup
<a name="API_CreateCacheSecurityGroup"></a>

Creates a new cache security group. Use a cache security group to control access to one or more clusters.

Cache security groups are only used when you are creating a cluster outside of an Amazon Virtual Private Cloud (Amazon VPC). If you are creating a cluster inside of a VPC, use a cache subnet group instead. For more information, see [CreateCacheSubnetGroup](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_CreateCacheSubnetGroup.html).
