Exam Overview
The Red Hat Certified Specialist in Advanced Cluster Security exam (EX430) evaluates your ability to secure Kubernetes and OpenShift environments using Red Hat Advanced Cluster Security for Kubernetes (RHACS).
This performance-based exam tests real-world skills required to identify vulnerabilities, enforce security policies, manage compliance, and detect runtime threats across the container application lifecycle.
By successfully passing the EX430 exam, you earn the Red Hat Certified Specialist in Advanced Cluster Security credential, which also counts toward the Red Hat Certified Architect (RHCA®) certification.

Study Points for the Exam
The following exam objectives highlight the key task areas that may be tested during the EX430 exam. Candidates should be able to demonstrate the skills listed below in a hands-on environment.
Secure the Container Build and Deployment Lifecycle
- Integrate RHACS into container image build pipelines
- Identify vulnerabilities in container images
- Interpret CVE severity and risk impact
- Enforce security policies at build and deploy time
Manage Vulnerabilities and Risk
- Analyze image and deployment vulnerabilities
- Prioritize remediation based on risk and exposure
- Generate vulnerability reports and dashboards
- Apply remediation strategies without disrupting workloads
Implement and Enforce Security Policies
- Configure and customize RHACS security policies
- Apply policies to control deployments and runtime behavior
- Monitor policy violations and alerts
- Automate security enforcement across clusters
Secure Kubernetes Network Communication
- Analyze application network flows using Network Graph
- Identify unnecessary or risky network connections
- Generate and apply Kubernetes network policies
- Implement Zero Trust networking principles
Detect and Respond to Runtime Threats
- Monitor container runtime behavior
- Detect suspicious system calls, processes, and network activity
- Investigate runtime security alerts
- Respond to security incidents effectively
Manage Compliance and Governance
- Run compliance scans using built-in standards
- Interpret compliance reports and findings
- Maintain continuous compliance across clusters
- Support audit and governance requirements
As with all Red Hat performance-based exams, all configurations must persist after reboot and operate without manual intervention.
You may be required to work with pre-configured Kubernetes or OpenShift clusters and existing workloads. Application source code modification is not required, but candidates must use provided documentation to secure and manage deployed applications.
