Overview of HashiCorp Boundary

HashiCorp Boundary is a secure remote access solution designed to provide simple and secure access to dynamic infrastructure across various environments. Unlike traditional SSH bastion hosts, Boundary allows you to manage access to applications and critical systems without exposing the underlying network, offering a more secure and efficient way to handle remote user access.

Key Features of HashiCorp Boundary

Identity-Based Access Control

HashiCorp Boundary provides a secure way to access hosts and critical systems through just-in-time access and role-based access controls. This ensures that access to sensitive systems is tightly controlled and monitored, reducing the risk of unauthorized access.

Integration with HashiCorp Vault

By integrating with HashiCorp Vault, Boundary enhances credential management. Vault securely stores and manages secrets, providing dynamic credentials for accessing critical systems, which Boundary uses to authenticate and authorize access based on trusted identities.

Dynamic Host Catalogs

Boundary’s dynamic host catalogs automatically discover and catalog new resources, simplifying access management and ensuring that access policies are always current.

Boundary

Enhancing User Access

Streamlined User Access

Boundary streamlines user access to dynamic infrastructure by leveraging identity-based access controls. This ensures that users can securely access the systems they need, without exposing the network to potential threats.

Multi-Cloud Support

Boundary can be deployed across multiple cloud environments, including AWS and Azure, providing a consistent and secure access management solution for infrastructure hosted on different platforms.

Automation and Credential Management

Credential Management

With Boundary, credentials are dynamically managed and injected when needed, reducing the need for static credential distribution and management. This approach enhances security and simplifies credential management.

Automation with Terraform

Boundary’s Terraform provider allows you to define access control policies as code, making it easy to automate and manage access configurations.

Secure Remote Access

Secure Access to Critical Systems

Boundary is a remote access solution that provides secure access to applications and critical systems. It ensures that remote user access is managed efficiently, with fine-grained authorizations based on trusted identities.

Authentication and Authorization

Boundary uses identity providers like Okta and Azure Active Directory to authenticate users, ensuring that only authorized individuals can access sensitive systems.

Session Management and Recording

Session Recording and Audit

Boundary’s session recording and audit features provide comprehensive visibility into user activities, enhancing security and compliance by allowing you to track and review access to critical systems.

Step-by-Step Guide

1. Install Boundary CLI

First, download and install the Boundary CLI from the official HashiCorp website. Below are the installation commands for different operating systems.

For Debian-based Linux (Ubuntu):

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
sudo apt-get update && sudo apt-get install boundary

For macOS using Homebrew:

brew tap hashicorp/tap brew install hashicorp/tap/boundary

For Windows using Chocolatey:

choco install boundary

2. Initialize Boundary

Initialize a development environment to start exploring Boundary features.

Command:

boundary dev

This command starts a local development instance of Boundary for testing and learning purposes.

3. Configure Authentication

Set up your authentication method. For example, to configure OIDC with Okta:

Command:

boundary auth-methods create oidc -name "okta" -url "https://your-okta-domain.okta.com" -client-id "your-client-id" -client-secret "your-client-secret"

Replace your-okta-domain.okta.comyour-client-id, and your-client-secret with your actual Okta domain and credentials.

4. Define Access Policies

Create roles and grants to define access policies.

Creating a Role:

boundary roles create -name "admin-role" -scope-id "global" -description "Admin role with full permissions"

Creating a Grant:

boundary grants create -role-id "admin-role-id" -scope-id "global" -principal-id "user-id" -type"admin"

Replace admin-role-id and user-id with your actual role and user IDs.

5. Deploy Boundary in Production

For production deployment, use the HashiCorp Cloud Platform (HCP) to deploy Boundary with ease.

Steps:

  1. Log in to the HashiCorp Cloud Platform.
  2. Navigate to the Boundary section.
  3. Follow the deployment steps provided in the HCP portal.

Example Usage

Creating a Project and Target

  1. Create a Project:shCopy codeboundary projects create -scope-id "global" -name "example-project" -description "Example Project"
  2. Create a Host Catalog:shCopy codeboundary host-catalogs create static -scope-id "project-id" -name "example-catalog" -description "Example Host Catalog"
  3. Add a Host to the Catalog:shCopy codeboundary hosts create static -host-catalog-id "catalog-id" -name "example-host" -address "192.168.1.1"
  4. Create a Target:shCopy codeboundary targets create tcp -scope-id "project-id" -name "example-target" -description "Example Target" -default-port 22 -session-connection-limit 10

Managing Sessions

  1. Start a Session:shCopy codeboundary connect ssh -target-id "target-id"
  2. Terminate a Session:shCopy codeboundary sessions delete -id "session-id"

Automating with Terraform

You can also manage Boundary resources using Terraform. Here is an example Terraform configuration:

provider "boundary" {
  // Configuration options
}

resource "boundary_scope" "example_scope" {
  name        = "example-scope"
  description = "Example Scope"
}

resource "boundary_host_catalog" "example_catalog" {
  scope_id    = boundary_scope.example_scope.id
  name        = "example-catalog"
  description = "Example Host Catalog"
}

resource "boundary_host" "example_host" {
  host_catalog_id = boundary_host_catalog.example_catalog.id
  name            = "example-host"
  address         = "192.168.1.1"
}

resource "boundary_target" "example_target" {
  scope_id              = boundary_scope.example_scope.id
  name                  = "example-target"
  description           = "Example Target"
  default_port          = 22
  session_connection_limit = 10
}
