Kubernetes Security on AWS: A Practical Guide
Kubernetes security is safeguarding your Kubernetes clusters, the applications they host, and the infrastructure they rely on from threats. As a container orchestration platform, Kubernetes is incredibly powerful but presents a broad attack surface for potential adversaries.
Kubernetes security encompasses several strategies and best practices to mitigate this risk, including hardening your containers and hosts, managing user permissions, implementing network policies, and setting up logging and monitoring.
One of the key aspects of Kubernetes security is the principle of least privilege, which implies that every component of your Kubernetes environment should have only the permissions it needs to function.
This minimizes the potential damage an attacker can do if they compromise a part of your system. Another foundational principle is defense in depth, layering different security controls so that a failure in one area does not lead to a complete system compromise.
However, it’s important to realize that Kubernetes environments are dynamic and constantly changing, with new workloads being deployed, old ones being updated or retired, and infrastructure being scaled up or down to meet demand.
This means your security posture needs to be continuously monitored and adjusted to keep up with these changes. Application mapping technology can help understand the current state of applications and dependencies in containerized environments.
