Binary Authorization is a deploy-time security control that ensures only trusted container images are deployed on Google Kubernetes Engine (GKE). With Binary Authorization, you can require images to be signed by trusted authorities during the development process and then enforce signature validation when deploying. By enforcing validation, you can gain tighter control over your container environment by ensuring only verified images are integrated into the build-and-release process.
Enforce standardized container release practices
Using Binary Authorization, DevOps teams can gain assurance that only explicitly authorized container images will be deployed to GKE. By verifying images prior to deployment, you can reduce the risk of unintended or malicious code running in your environment.
Put proactive security measures in place
Binary Authorization helps DevOps teams implement a proactive container security posture by ensuring only verified containers are admitted into the environment and that they remain trusted during runtime.
Native GCP integration
Binary Authorization integrates with the GKE control plane to allow or block image deployment based on the policies that you define. You can also leverage integrations with Cloud Build and Container Registry Vulnerability Scanning to enable deploy-time controls based on build information and vulnerability findings.
Define policies at the project and cluster levels based on the security requirements of your organization. Create distinct policies for multiple environments (e.g., production and test) in addition to CI/CD setups.
Policy verification and enforcement
Enforce policies by using Binary Authorization to verify signatures from vulnerability scanning tools like Container Registry Vulnerability Scanning, third-party solutions, or image signatures you generate.
Cloud Security Command Center integration
View results for policy violations as part of your single pane of glass for security in Cloud Security Command Center (CSCC). Explore events such as failed deploy attempts due to policy restriction, or breakglass workflow activities.
Maintain a record of all policy violations and failed deployment attempts using Cloud Audit Logging.
Cloud KMS support
Use an asymmetric key you manage in Cloud Key Management Service to sign images for signature verification.
Open-source support for Kubernetes
Use the open-source Kritis tool to enforce signature verification across both on-premises Kubernetes and cloud GKE deployments.
Test changes to your policy in non-enforcing mode before deploying. See results including would-be-blocked deployments in Cloud Audit Logging.
Bypass policy in an emergency using the breakglass workflow to ensure you aren't impeded from incident response. All breakglass incidents are recorded in Cloud Audit Logging.
Integration with third-party solutions
Integrate Binary Authorization with leading container security and CI/CD partners, such as CloudBees, Twistlock, and Terraform.
