Tigera highlighted the need to secure AI workloads on Kubernetes, pointing out that while AI security challenges aren't new, the stakes are higher due to the sensitive data and powerful APIs involved. Solutions include securing API endpoints with the Kubernetes Gateway API, using network policies enforced by CNIs like Calico or Cilium, restricting API keys using IP address restrictions or egress gateways, and implementing observability with tools like OpenTelemetry.

<strong>From key sprawl to scalable control: Rethinking SSH access (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Static SSH keys create security and operational challenges at scale due to long lifetimes, sharing, and lack of auditability, while SSH certificates provide short-lived, signed access controlled by a certificate authority. HashiCorp Vault and Boundary streamline SSH certificate management by dynamically generating and injecting ephemeral credentials, enabling secure, auditable, and scalable SSH access with centralized policy and minimal user overhead.
