securityGroupIds

A list of security groups IDs that are available to attach to your server's endpoint.

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.
