Disabling SSH access to elastic instances
By default, SSH (Secure Shell) access is enabled for elastic instances, the first time that you use Elastic Bamboo. Access rules for the Amazon Elastic Compute Cloud (EC2) are managed by 'security groups' in the Amazon Web Services Console. You can disable SSH access for your elastic instances by changing the EC2 access rules to remove the 'SSH' Connection Method from the 'elasticbamboo' security group.
For instructions on changing the EC2 access rules for Elastic Bamboo, please read the Elastic Bamboo Security document.
