ServiceNow Terraform Plugin: No-Code, Tags, and Security Boost

This week marks the release of significant updates to two essential ServiceNow plugins for Terraform, enhancing their functionality and security features. These updates are designed to streamline infrastructure management and provide more secure integrations, reflecting the evolving needs of users in today’s technology landscape. Let’s delve into the details of these updates and explore how they can benefit users.

Version 2.8 of ServiceNow Service Catalog for Terraform

The first update involves the release of version 2.8 of the ServiceNow Service Catalog for Terraform. One of the most notable features introduced in this version is the ability for users to specify an execution mode when provisioning infrastructure using no-code workspaces. This enhancement addresses a long-standing request from users who have been seeking more control over their infrastructure provisioning processes.

What is Execution Mode?

Execution mode is a setting that determines where and how Terraform runs are executed. There are two execution modes supported in this update:

1. Remote Execution Mode: This mode utilizes HashiCorp’s Cloud Platform (HCP) to perform Terraform runs. It is ideal for users who prefer to offload execution to a managed cloud environment.
2. Agent Execution Mode: This mode allows users to specify which agent pool will execute the run. It offers more customization and control over the execution environment, which can be crucial for organizations with specific infrastructure needs or constraints.

   By providing these options, administrators can select the most suitable execution environment based on their unique requirements, enhancing the provisioning workflow for no-code workspaces.

   Storing Terraform Workspace Tags as Key-Value Pairs
   

   In addition to execution mode specification, the update also introduces support for storing Terraform workspace tags as key-value pairs. Tags are metadata that help categorize and organize resources, making it easier for administrators to manage and track workspaces.

   Previously, tags were supported in a flat-string list format, which offered basic categorization capabilities. However, the new key-value pair format allows for more detailed and meaningful categorization. This means administrators can associate additional metadata with each workspace, offering greater flexibility and precision in managing Terraform resources.

   The update affects both the backend and frontend of the ServiceNow Service Catalog for Terraform. On the backend, the "Create Workspace" request body now includes tag-bindings in the relationships attribute. On the frontend, users can enter tags in the "Workspace Tags" field using a format like "env: prod, instance: test".

   Version 1.2 of Service Graph Connector for Terraform
   

   The second major update is the release of version 1.2 of the Service Graph Connector for Terraform. This update introduces a critical security enhancement by adopting advanced encryption standards, providing a more secure connection between HCP Terraform and the ServiceNow Configuration Management Database (CMDB).

   Enhanced Security Features
   

   Previously, the app used a mechanism to decrypt HMAC tokens included in webhook notification requests sent by HCP Terraform. With the new update, the app now uses ServiceNow’s native Certificate Encryption API to process these tokens. This change aligns with security best practices recommended by ServiceNow and the National Institute of Standards and Technology (NIST), ensuring secure access to the request body and facilitating the import of Terraform resources into the ServiceNow CMDB.

   This improved security feature allows users to confidently import Terraform resources into the CMDB, knowing their data and connections are protected by the latest security enhancements.

   Benefits of the Updates
   

   These updates to the ServiceNow plugins for Terraform offer several benefits to users:

   • Improved Control and Customization: The ability to specify execution modes provides users with greater control over their infrastructure provisioning workflows, allowing them to tailor the process to their specific needs.
   • Enhanced Resource Management: The introduction of key-value pair tags enables more granular categorization of workspaces, enhancing the organization and tracking of Terraform resources.
   • Increased Security: The adoption of advanced encryption standards in the Service Graph Connector for Terraform ensures secure integration with the ServiceNow CMDB, protecting sensitive data and connections.
     

     Good to Know
     

     As infrastructure management becomes increasingly complex, tools like Terraform and ServiceNow play a crucial role in simplifying and securing these processes. By continuously updating and improving their integrations, these platforms help organizations stay ahead of evolving security threats and operational challenges.

     For organizations that rely on Terraform for infrastructure provisioning, these updates represent a significant step forward in terms of both functionality and security. By adopting these new features, administrators can enhance their workflows and ensure their infrastructure remains secure and well-managed.
