Deploy a Secure Device Connector on an AWS VPC Using a Terraform Module

Before you begin

Review these prerequisites before attempting to deploy an SDC on your AWS VPC:

  • Security Cloud Control requires strict certificate checking and does not support Web/Content Proxy inspection between the SDC and the Internet. If using a proxy server, disable inspection for traffic between the Secure Device Connector (SDC) andSecurity Cloud Control.

  • See Connect Cisco Security Cloud Control to the Secure Device Connector to ensure proper network access.

  • You require an AWS account, an AWS VPC with at least one subnet, and an AWS Route53-hosted zone.

  • Ensure you have the Security Cloud Control bootstrap data, your AWS VPC ID, and its subnet ID handy.

  • Ensure that the private subnet to which you deploy the SDC has a NAT gateway attached.

  • Open traffic on the port on which your firewall management HTTP interface is running, from your firewalls to the Elastic IP attached to the NAT gateway.

Procedure

Step 1

Add the following lines of code in your Terraform file; make sure you manually enter inputs for variables:

module "example-sdc" {
  source             = "git::https://github.com/cisco-lockhart/terraform-aws-cdo-sdc.git?ref=v0.0.1"
  env                = "example-env-ci"
  instance_name      = "example-instance-name"
  instance_size      = "r5a.xlarge"
  cdo_bootstrap_data = "<replace-with-cdo-bootstrap-data>"
  vpc_id             = <replace-with-vpc-id>
  subnet_id          = <replace-with-private-subnet-id>
}

See the Secure Device Connector Terraform module for a list of input variables and descriptions.

Step 2

Register instance_id as an output in your Terraform code:

output "example_sdc_instance_id" {
  value = module. example-sdc.instance_id
}

You can use the instance_id to connect to the SDC instance for troubleshooting using the AWS Systems Manager Session Manager (SSM). See Outputs in the Secure Device Connector Terraform module for a list of available outputs.

What to do next

For any troubleshooting of your SDC, you need to connect to the SDC instance using AWS SSM. See AWS Systems Manager Session Manager to know more about how to connect to your instance. Note that the ports to connect to the SDC instance using SSH are not exposed because of security reasons.
