securityGroupIds
A list of security groups IDs that are available to attach to your server's endpoint.
While SecurityGroupIds appears in the response syntax for consistency with CreateServer and UpdateServer operations, this field is not populated in DescribeServer responses. Security groups are managed at the VPC endpoint level and can be modified outside of the Transfer Family service. To retrieve current security group information, use the EC2 DescribeVpcEndpoints API with the VpcEndpointId returned in the response.
This property can only be set when EndpointType is set to VPC.
You can edit the SecurityGroupIds property in the UpdateServer API only if you are changing the EndpointType from PUBLIC or VPC_ENDPOINT to VPC. To change security groups associated with your server's VPC endpoint after creation, use the Amazon EC2 ModifyVpcEndpoint API.
