| 6 |  AI can quickly create Kubernetes changes, but it is still important to validate them.
Mauricio Salatino from Dash0 tests generated manifests before releasing them. He uses tools like vCluster Bind and provides clear examples to ensure the output matches established patterns.
Good governance begins with testing, understanding the context, and setting clear expectations.

| 8 |  This article covers network security fundamentals in Kubernetes, explaining how clusters default to a flat pod network, how network policies enforce segmentation, and best practices like “default deny” and restricting host networking.

| 9 | Hortator lets AI agents spawn sub-agents at runtime, with each agent running in its own pod with budget caps, network policies, PII redaction, and capability inheritance so children can never escalate beyond their parent's permissions.

| 10 | Artem Lajko explains OS-level observability - the deepest layer of Kubernetes monitoring focused on infrastructure security and performance.
He describes how specialized tools like Falco and eBPF monitor system calls and kernel events to detect security threats. Using the example of unauthorized container shell access, Artem demonstrates how this layer provides platform teams and security engineers with deep insights while maintaining system performance.

| 13 | Nicholaos Mouzourakis, Staff Product Security Engineer at Gusto, explains how they implemented auditable decision logging for Open Policy Agent (OPA) in their Kubernetes environment. He describes how Styra's Declarative Authorization Service (DAS) ingests and indexes OPA decision logs from all instances, making them searchable in a centralized location.
Nicholaos details how DAS enables:
- Searching for actions taken by specific users
- Identifying users with access to particular resources
- Tracking when and how access was granted
- Simulating policy changes against historical decision logs
He also mentions how they overcame challenges with legacy batch decision logs that weren't easily searchable by implementing a new batch API provided by Styra.
