Cedar Joins CNCF: Policy-as-Code Takes Center Stage

Deconstructing Cedar's Authorization Power

The move of Cedar to the CNCF as a Sandbox project is a significant development in the cloud-native authorization space. The emphasis on formal verification and the Rust implementation are particularly noteworthy, as they address critical security concerns in a field where vulnerabilities can have severe consequences. The potential for policy-as-code to streamline access control and improve developer velocity is also compelling. However, the article doesn't delve deeply into the practical challenges of migrating to Cedar. While the article mentions integrations with other open-source projects, a more in-depth discussion of interoperability and potential conflicts with existing authorization systems would be beneficial.

One potential limitation is the learning curve associated with the Cedar language itself. While the article highlights its expressiveness and analyzability, developers will need to invest time in learning the language and its associated tooling. The article also doesn't provide detailed comparisons with other authorization solutions like AWS IAM or other open-source alternatives beyond OPA, which could help developers evaluate its suitability for their specific use cases. Furthermore, although the focus on performance for applications with millions of users is a strong selling point, concrete performance benchmarks and comparisons would strengthen the argument. The article could benefit from a deeper analysis of the trade-offs between expressiveness and performance, especially in complex authorization scenarios.

Finally, while the CNCF Sandbox status is a good starting point, the project's long-term sustainability will depend on the community's engagement and the availability of resources for ongoing development and maintenance. The article could have elaborated on the project's roadmap, community involvement, and potential funding mechanisms to give readers a clearer picture of its future prospects.

Key Points

• Cedar, an authorization policy language and SDK, joins CNCF as a Sandbox project, offering a vendor-neutral standard for fine-grained permissions in cloud-native applications.
• Cedar emphasizes policy-as-code, allowing developers to define permissions as policies and decouple access control from application logic, supporting RBAC, ABAC, and ReBAC models.
• The language prioritizes assurance and safety through formal verification using the Lean theorem prover and differential random testing, crucial for security-sensitive operations.
• Cedar offers advanced tooling, including a policy validator, and is designed for high-performance evaluation in applications with millions of users and resources.
• The move to CNCF facilitates vendor-neutral governance, broader contributor base, and deeper integration within the cloud-native landscape.
