Hexa Policy Mapper Project
The Hexa Policy-Mapper Project provides administrative tools and development libraries for provisioning and mapping various policy systems into a common policy format known as IDQL. With Policy Mapper and IDQL, you can manage all your access policies consistently across software providers and cloud systems. The project includes a number of prebuilt integrations (we call them providers) as well as guidance on how to build your own providers.
This project provides:
- a GoLang SDK which can be used in open source and commercial implementations to leverage this community library.
- a Hexa CLI command line tool which can be used to provision policies to web accessible policy systems.
- a GoLang interface (policyprovider.Provider) enabling the development of new policy provisioning providers.
[!Tip] Policy-Orchestrator is available as a sample web server implementation that uses Policy-Mapper.
[!Note] This project is currently under initial development and documentation may be out of date.
Supported Provider Integrations
Policy Mapper supports the following capabilities:
Syntactical Mapping : Policy formats that have a parsable format or language, and can be represented in a "tuple" (subject, action, resource, conditions, scope) are considered "syntactical". Policy-Mapper can map these formats to and from IDQL JSON format. Examples include: IDQL, Cedar, GCP Bind among others.
RBAC API Mapping : Some systems do not directly have a policy language but support role or group based access control settings through an API.
Policy Provisioning : Policy Mapper combines a set of Providers that call APIs to retrieve and map access policy as well as be able to set policy.
Syntactical Mapping support is provided for:
- Google Bind Policy and Google Conditional Expression Language (CEL)
- AWS Verified Permissions and Cedar policy language including support for CEL
Provisioning support is provided for:
- Google Policy for IAP Secured Resources (Application Engine and Compute Engine)
- Amazon Verified Permissions
- OPA Open Policy Agent with Extensions to Support IDQL and an OPA Extension Plugin to support ABAC policy (conditions) processing
- Provisioning to RBAC based policy systems including (to be ported from hexa-org/policy-orchestrator):
- Amazon
- Microsoft Azure
Getting Started
Installation
Install go 1.21, clone and build the project as follows:
git clone https://github.com/hexa-org/policy-mapper.git
cd policy-mapper
sh ./build.sh
Hexa CLI Tool
To test the Hexa SDK and or develop using scripts, use the Hexa CLI tool.
To run the Hexa CLI, simply type hexa at the command line once installed.
[!Note] Hexa CLI currently does not support filenames with spaces. Valid example: add gcp --file=my_key.json
Hexa Developer Documentation
To start using the Hexa Mapper SDK in your GoLang project, perform the following get command:
go get github.com/hexa-org/policy-mapper
For more details on how to map or provision policy in either console (shell) form or GoLang, see: Developer documentation.
Provider Documentation
Each provider in the providers directory structure has its own README.md that describes the provider and its capabilities and limitations.
