Yes, some users may see value in Boundary providing access to an existing bastion host deployment. The advantages to Boundary's access model are outlined above.Ĭan Boundary extend a Bastion/Jumphost access model? Yes, in many cases you can use Boundary as a replacement for an existing bastion host-based access model to infrastructure. You can use SSH to inject the credentials of any target resources that you want to connect to using Boundary, so that the credentials are never exposed to the user while establishing a connection.Īlternatively, Boundary can return brokered credentials back to users (if permitted), which could take the form of API tokens, usernames and passwords, public keys, etc.Ĭan Boundary replace a Bastion/Jumphost access model? IT departments now have to manage updates for another server and the sprawl of infrastructure continues, increasing your attack surface, and requiring your IT department to be perfect.īoundary is not a traditional bastion host.īoundary streamlines just-in-time access to privileged sessions for users, and tightly controls access to infrastructure with role-based access controls (RBAC).īoundary validates a user's identity using your identity provider of choice, and then dynamically grants them access to the resources they need using their associated permissions.īoundary's worker nodes, the resources that proxy connections to private endpoints, are fundamentally stateless and can be easily scaled elastically using modern development tools. Maintaining security groups, network ACLs, and IAM controls on a bastion host at a per-user level is nearly impossible, unless you create and maintain multiple bastion hosts per user or group. The public IP address must be in the same region as the Bastion resource you're creating. ![]() The Public IP address section is where you configure the public IP address of the Bastion host resource on which RDP/SSH will be accessed (over port 443). If you want to set up your cloud environment securely, you may choose to run all of your important workloads behind a NAT Gateway, and provision a DMZ with a set of hardened bastion servers.īastion host security groups are often not locked down at the network layer.Īdditionally, users who log into a bastion host using SSH are typically dropped into a privileged account. At the top of the Subnets page, select Create a Bastion to return to the Bastion configuration page.
