"IAMbic: Version Control for IAM"

IAMbic is designed for DevSecOps, Security, and Compliance teams. It provides enhanced visibility, auditing, and (optionally) control over IAM at scale. It integrates with IAM sources like AWS, Okta, Azure AD, and Google Workspace, consolidating them into a single version control system (Git) in a common, human-readable YAML files that are called "IAMbic templates".

Whether you're managing resources through Terraform, CDK, CloudFormation, manual console operations, or a combination of these, IAMbic keeps your Git repository updated with the real-time state of your cloud IAM. Any IAM change, irrespective of its origin, triggers a git commit. This ensures you have a consolidated Git repository of all your IAM, presented in a common format, complete with a comprehensive audit trail in Git History. This trail details every change, its timestamp, and the responsible entity.

If you'd prefer a hands-off approach, IAMbic can function purely as an auditing and visibility tool to have increased visibility over IAM changes, as mentioned above. But you can also use IAMbic to manage and prevent drift on the IAM resources that you specify. IAMbic templates are bi-directional, which means IAMbic can also write IAM changes back to the cloud through your CI/CD pipeline. A pull request with the desired change would be created in GitHub, approved, and then reflected back in the cloud and Git. Additionally, IAMbic lets you declare temporary access or permissions - It will take care of expiring and removing policies after a defined expiration period. Examples of this are in IAMbic's Quick Start Guide.

If you'd like to learn more about the Github Pull-Request flow for making IAM changes, Check out an example on our GitOps/IAMOps Philosophy page. We also have a sample iambic-templates repository, which is fully managed by IAMbic.

IAMbic is designed to work in harmony with Terraform and other Infrastructure-as-Code (IaC) solutions. It acts as a complementary tool, enhancing the strengths of existing IaC setups by providing centralized visibility and auditing for Identity and Access Management (IAM). To understand how IAMbic and Terraform elevate IAM together, and how they can be integrated seamlessly in your DevOps pipeline, check out our in-depth blog post.

Below is a table of the key differences between IAMbic and Terraform:

• Version Control for IAM: IAMbic helps you audit and (optionally) manage IAM from different sources by bringing them together into one Git repository in an easy-to-read format.
• Comprehensive audit trail: IAMbic creates Git commits for all IAM changes, regardless of how they take place. This gives you a comprehensive audit trail in Git history.
• Temporary Access and Permissions: Declaratively define and automate expiration dates for resources, permissions, and access rules.
• Drift Prevention: Protect the IAM resources you want to be exclusively managed via IAMbic. IAMbic will automatically revert any out-of-band changes to those resources.
• Dynamic AWS Permissions: Simplify multi-account AWS management with flexible templates, allowing multi-account roles to have different permissions and access rules on different accounts.
• Centralized Management: IAMbic keeps Git updated with the latest, complete state of your cloud environment, maintaining a single source of truth for auditing and compliance across multiple cloud providers in Git.
• Extendable: Integrate with various clouds and applications through a powerful plugin architecture.
• Auditable: Track changes to IAM policies, permissions, and rules with Git history. For AWS, IAmbic annotates out-of-band commits with details from CloudTrail.

1. Install the required Prerequisites
2. Install and configure IAMbic

Here are some examples showcasing IAMbic's capabilities:

Create a Cloudwatch role with static permissions across three accounts, dynamically generating role names based on the account the role is deployed to. This template would result in the creation of three roles: "dev_cloudwatch", "staging_cloudwatch", and "prod_cloudwatch" on the respective AWS accounts.

See the Getting Started guide for AWS, the AWS IAM Role section of our Example Templates repository, and our blog post on multi-account roles for more information.

Managing access to AWS services can be a tricky business. That's where Service Control Policies (SCPs) come in. SCPs allow you to define what services and actions are accessible within your AWS accounts. With IAMbic, you can import your existing SCPs, create new ones that restrict access to specific AWS services, and prevent any drift from occurring to ensure that you're protecting sensitive information the way you intend.

For instance, let's say you want to limit access to certain AWS regions. You can create an SCP that denies access to all regions except those you specify. This can be particularly useful if you're looking to maintain tighter control over your data residency and compliance.

Here's an example of how you can set this up:

template_type: NOQ::AWS::Organizations::SCP
account_id: '123456789012'
iambic_managed: enforced
identifier: RestrictRegions
org_id: o-123456
properties:
  policy_document:
    statement:
      - condition:
          StringNotEquals:
            aws:RequestedRegion:
              - us-east-1
              - us-west-2
        effect: Deny
        not_action:
          - a4b:*
          - budgets:*
          - ce:*
          - chime:*
          - cloudfront:*
          - cur:*
          - globalaccelerator:*
          - health:*
          - iam:*
          - importexport:*
          - mobileanalytics:*
          - organizations:*
          - route53:*
          - route53domains:*
          - shield:*
          - support:*
          - trustedadvisor:*
          - waf:*
          - wellarchitected:*
        resource:
          - '*'
  policy_name: RestrictRegions
  targets:
    roots:
      - r-123

In this example, the SCP named RestrictRegions denies access to all AWS regions except us-east-1 and us-west-2. It also excludes certain global services from the restriction.
