The following role is the minimum required for the connection. To enable connection by using Session Manager, you need to have AWS Systems Manager Agent (SSM Agent) installed on the Amazon EC2 instance, and you need to add an AWS Identity and Access Management (IAM) role to the instance that grants access to Systems Manager. A key pair is not required if you are testing the connection using only the AWS CLI or the AWS Systems Manager console. If you don’t have a key pair, create one before following the rest of the steps below. To work through this blog post, if you are testing the connection by using SSH, you need the name of an existing public/private key pair, which allows you to connect securely to your instance after it launches. Before you startįor details on Session Manager, see the Getting Started with Session Manager documentation. Instructions for access using Amazon Elastic Compute Cloud (Amazon EC2) Instance Connect will follow in the second blog post. In this first part of this two-part blog series, I present an overview of the automation required to enable SSH access by using AWS Session Manager. To learn more about the benefits, see the AWS Systems Manager Session Manager documentation. With Session Manager, you don’t have to open inbound access to secure shell (SSH) ports and remote Microsoft Windows PowerShell ports. This greatly improves your security and audit posture by centralizing access control and reducing inbound access. Amazon Web Services (AWS) has recently released two new features that allow us to connect securely to private infrastructure without the need for a bastion host. It provides near-like console access that does not require any public IP address or VPN gateway connectivity to the VMs it connects to.Using a bastion or jump server has been a common way to allow access to secure infrastructure in your virtual private cloud (VPC) and is integrated into several Quick Starts. It enables the use of the Azure Portal to perform the RDP and SSH connection to any virtual machine within the virtual network they are deployed in with a secure, cost effective solution. Even a jump box exposed to the public Internet has several security risks.Īzure Bastion is the Platform as a Service (PaaS) solution to a jump box in Azure. Microsoft Azure, being a cloud solution, understands that users cannot expose RDP and SSH to the public internet in most scenarios. It is explicitly used to provide a controlled means of access to manage other resources in the network. It is typically more locked down and hardened and only accessible from a trusted network. This server can be on your DMZ or internal network. In some scenarios that may be true depending on how the resource was deployed.Ī Jump box server, while very similar to a Bastion host, is slightly different. Some use Bastion and Jump box interchangeably. This host is typically placed in outside your network or security zone to protect against attacks and not expose your internal resources to the public Internet. In technology, a Bastion host is used to securely connect to resources on your network, typically for a single purpose.
