By default, when a new cluster security group is created, it has no ingress rules.This example modifies

a new cluster security group by adding two ingress rules. One ingress rule is added by specifying a

CIDR/IP range; the other is added by specifying an owner ID and Amazon EC2 security group combination.

For step-by-step instructions to run the following example, see Running Java Examples for Amazon

Redshift Using Eclipse (p. 130).You need to update the code and provide a cluster identifier and AWS

account number.

import java.util.ArrayList;

public class CreateAndModifyClusterSecurityGroup {

public static AmazonRedshiftClient client;

public static String clusterSecurityGroupName = "securitygroup1";

CreateAndModifyClusterSecurityGroup.class

.getResourceAsStream("AwsCredentials.properties"));

client = new AmazonRedshiftClient(credentials);

try {

createClusterSecurityGroup();

describeClusterSecurityGroups();

addIngressRules();

associateSecurityGroupWithCluster();

} catch (Exception e) {

System.err.println("Operation failed: " + e.getMessage());

}

curityGroupName);

}
