# Redshift Cluster Security Group

An Amazon Redshift Cluster Security Group acts as a virtual firewall that controls network access to Redshift clusters. It defines inbound rules that specify which IP ranges or Amazon EC2 security groups can connect to the cluster. This resource is used in the EC2-Classic network model and helps manage secure connectivity to Redshift without relying on VPC security groups.
