Cilium, Medium (Advanced), Security. https://k8wiz.com/uquiz/what-is-the-purpose-of-ciliums-identity-based-security

- A. To authenticate users accessing the Kubernetes API
- B. To secure communication between Cilium components
- C. To assign unique identities to workloads for policy enforcement
- D. To verify the identity of container images

**Answer:** To assign unique identities to workloads for policy enforcement

**Explanation:** Cilium's identity-based security assigns unique identities to workloads (like pods) based on their labels. These identities are used for policy enforcement, allowing Cilium to control which workloads can communicate with each other based on their identities rather than IP addresses, which can change frequently in Kubernetes environments.
