permify VS OPA (Open Policy Agent)

However, in this piece we're focusing on the PBAC model also known as Policy-Based Access Control and how it differentiates itself these from traditional access control models in terms of scalability, flexibility and security.

Hi I'm Karan, one of the maintainers of Permify (https://github.com/Permify/permify), an open source authorization service to build scalable authorization systems.

I want to share with you that we've built an AI assistant to help modeling your desired authorization logic! You can basically describe your authorization logic in Permify AI and it will generate the respective model and semantics accordingly. Think of it like ChatGPT for authorization modeling/policy generation.

Here's the project if you would like to play with it: https://ai.permify.co/.

Brief backstory:

Since authorization is generally a domain specific issue use cases vary widely - roles, relationships, attributes, hierarchies between business units, contextual permissions, etc.

To address this, we're offering a domain specific language that we built purely using golang to help model authorization logic programmatically. You can see what it looks like with sample examples in our playground: https://play.permify.co/

Although our domain specific language helps our users significantly, the general idea of policy generation is hard challenging if you have complex authorization logic and versatile permission requirements. Additionally, the flexibility of our modeling language allows for achieving the same policy/permissions through various approaches. But creating the best possible policy is crucial for several reasons including the performance of access checks, the readability of the authorization logic, visibility, and achieving least privilege, etc.

When we tallied up all those reasons, it hit us: using AI could really smooth out the policy generation process. It could not only reduce the engineering effort but also yield the best possible results. That's why we integrated Groq to make to create Permify AI!

Would love to get your feedback on this!

At that point consider exploring our solution, Permify. It's a Google Zanzibar-based open-source authorization service that helps to build scalable authorization systems.

Additional to shifts from large tech companies, ReBAC based solutions increased over the time. We're also one of them, building an open source authorization service that builds its core on top of ReBAC and Google Zanzibar.

Permify is an open-source service for creating and managing complex permissions in applications, inspired by Google Zanzibar. It offers a flexible authorization language compatible with various models like RBAC, ReBAC, and ABAC, and allows for efficient authorization data management in preferred databases. Permify's API facilitates access checks, resource filtering, and bulk permission analyses. It also includes comprehensive testing tools for authorization logic, including scenario-based testing and policy coverage analysis. Additionally, Permify supports multi-tenancy, enabling distinct authorization models for different applications within a single instance.

As Permify we're building open source authorization infrastructure to build fine grained authorization systems at scale. Would love to learn your use case and help you to build robust authorization systems. Don't hesitate to reach us from our Discord Channel!

I’m one of the maintainers of the OSS project Permify (https://github.com/Permify/permify), an open-source authorization service inspired by Google Zanzibar, which is the global authorization system used at Google to handle authorization for hundreds of its services and products, including YouTube, Drive, Calendar, Cloud, and Maps.

Hi folks,

I’m one of the maintainers and co-founder of the Go OSS project Permify (https://github.com/Permify/permify), an open-source authorization infrastructure inspired by Google Zanzibar.

I would like to share a post where we aimed to provide a brief overview of how we integrated WASM with Golang to provide a richer user experience in our open-source playground. You can use the playground to create and test any authorization logic in a browser.

The playground has three main sections:

Schema: to model your authorization logic through our domanin specific language we built.

Data: to create sample authorization data according to the model for use in tests.

Enforcement: to test your authorization structure bt access check scenarios.

Here's the post if you're interested: https://www.permify.co/post/wasm-go/

And here's the playground: https://play.permify.co/

Appreciate your time!

How can we handle this? Are there any mechanisms to prevent or at least to some extent safeguard this kind of issues without falling back to a manual workflow? There is. One huge advantage of sticking to (de-facto) standards like Terraform is that first we are probably not the first ones to come up with this question and second there is a huge ecosystem around Terraform that might help us with such challenges. And for this specific scenario the solution is the Open Policy Agent. Let us take a closer look how the solution could look like.

A popular Policy-as-Code tool for Terraform is OPA, everyone's favorite versatile open-source policy engine that enforces security and compliance policies across your cloud-native stack, making it easier to manage and maintain consistent policy enforcement in complex, multi-service environments.

Harness Policy As Code uses Open Policy Agent (OPA) as the central service to store and enforce policies for the different entities and processes across the Harness platform. In this section, you will define a policy that will deny a pipeline execution if there is no approval step defined in a deployment stage.

OPA: While OPA is an open-source, general-purpose policy engine capable of enforcing unified and context-aware policies throughout the stack, it can also accept and output data in formats such as JSON, effectively functioning as a tool for generating or modifying configurations. Although it does not provide out-of-the-box schema definition support, it allows the integration of JsonSchema definitions.

In essence, container image signing involves adding a digital stamp to an image, affirming its authenticity. This digital assurance guarantees that the image is unchanged from creation to deployment. In this blog, I'll explain how to sign container images for Kubernetes using Cosign and the Open Policy Agent. I will also share a tutorial that demonstrates these concepts.

In this post we will explores two powerful solutions for addressing this issue: the Open Policy Language (OPA) and Google’s Zanzibar.

Rego is a declarative query language from the makers of the Open Policy Agent (OPA) framework. The Cloud Native Computing Foundation (CNCF) accepted OPA as an incubation-level hosted project in April 2019, and OPA graduated from incubating status in 2021.

Now there are more subdivided practice: * Policy as Code: Sentinel, OPA * Database as Code: bytebase * AppConfiguration as Code: KusionStack, Acorn * ...... (Welcome to add more)
