Shielding your Kubernetes runtime with image scanning on admission controller

Implementing image scanning on Kubernetes admission controllers provides a robust last line of defense for securing clusters by ensuring that all deployed images adhere to security policies. Admission controllers, a native Kubernetes feature, intercept API requests before object persistence, enabling them to block the deployment of non-compliant images. Various strategies exist for implementing this, ranging from DIY open-source integrations using tools like Anchore, Falco, and OPA, to commercial solutions like the Sysdig Admission Controller. The latter offers streamlined setup and operation, with features such as centralized scan results, policy reuse, and continued protection even during connectivity issues. Incorporating image scanning at this stage complements other security measures, addresses vulnerabilities in manual deployments, and enhances overall cluster security.
