     <h2>Security Considerations</h2>
     <p>You should make sure that your MACI instance is accessible from the workers. We recommend to use security groups in the AWS firewall, e.g., as described <a href="http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html#adding-security-group-rule">here</a>. 
     Just add a security group to all launched workers (specify it in the appsettings.json) and add a rule to your MACI instance allowing incoming traffic on port 63658 for this group.</p>
