Creates a new cache security group. Use a cache security group to control access to one or more cache clusters.
Cache security groups are only used when you are creating a cache cluster outside of an Amazon Virtual Private Cloud (Amazon VPC). If you are creating a cache cluster inside of a VPC, use a cache subnet group instead. For more information, see CreateCacheSubnetGroup.
