Whether to associate the AWS OpsWorks built-in security groups with the stack's layers.
AWS OpsWorks provides a standard set of built-in security groups, one for each layer, which are associated with layers by default. UseOpsworksSecurityGroups allows you to provide your own custom security groups instead of using the built-in groups. UseOpsworksSecurityGroups has the following settings:
True - AWS OpsWorks automatically associates the appropriate built-in
security group with each layer (default setting). You can associate additional security groups with a layer after you create it, but you cannot delete the built-in security group.
False - AWS OpsWorks does not associate built-in security groups with
layers. You must create appropriate EC2 security groups and associate a security group with each layer that you create. However, you can still manually associate a built-in security group with a layer on. Custom security groups are required only for those layers that need custom settings.
