Binary Authorization

Azure Binary Authorization is a security service provided by Microsoft Azure that helps enforce code integrity and policy-based deployment of containerized applications. It enables organizations to establish a secure and controlled environment by verifying and authorizing the deployment of container images before they are executed.

‍

With Azure Binary Authorization, organizations can define and enforce policies that dictate which container images are allowed to run in their environment. These policies can specify criteria such as image signatures, vulnerability scans, or specific registry sources that must be met before allowing the execution of containerized applications.

‍

The service integrates with Azure Container Registry, allowing organizations to store and manage their container images securely. Azure Binary Authorization ensures that only authorized and trusted images are deployed, reducing the risk of running malicious or unverified code in the environment.

‍

Azure Binary Authorization employs a webhook-based architecture that integrates with various admission controllers, such as Azure Kubernetes Service (AKS) or Azure Policy. These admission controllers intercept container deployment requests and consult the defined policies to determine whether the deployment should be authorized or denied.

‍

By enforcing strict authorization policies, Azure Binary Authorization helps organizations maintain compliance, enhance application security, and protect against unauthorized or compromised container images. It provides an additional layer of defense in containerized environments, ensuring that only validated and trusted software is executed.
