Why is Kubernetes secret management critical for security?

Kubernetes stores sensitive data, like passwords and API keys. Mismanaging secrets can lead to data leaks and security breaches, so it’s important to encrypt and carefully control access to them.

What is API server security in Kubernetes, and how do you secure it?

The API server is the control plane component that manages the cluster. Securing it involves using Transport Layer Security (TLS), authenticating requests, enabling audit logs, and using strong authentication methods.

Why should you regularly update Kubernetes and its components?

Outdated Kubernetes components may have vulnerabilities that hackers can exploit. Regularly updating ensures you have the latest security patches, features, and performance improvements.

What is pod security, and how do pod security policies (PSPs) help?

Pod security involves ensuring that pods are deployed with minimal privileges. Pod security policies enforce security standards for deployments, such as disallowing root access, and control how containers are executed.

How can audit logging help in detecting security issues?

Audit logging tracks all API requests made within the cluster, helping identify suspicious activity or unauthorized access attempts. It provides visibility into potential breaches and enables quick incident response.

What are the best practices for securing Kubernetes nodes?

Securing Kubernetes nodes is crucial to protecting the overall cluster. Best practices include using minimal base images for containers to reduce the attack surface, as smaller images contain fewer potential vulnerabilities. Regularly patching and updating nodes ensures that any known security flaws are addressed promptly. Implementing a host firewall helps block unnecessary traffic, reducing exposure to potential threats. It’s also important to disable root access and run containers with the least privileges required. Additionally, enforcing encryption for data at rest and in transit ensures sensitive information remains secure.

What are Kubernetes Network Policies?

Kubernetes Network Policies are a set of rules that control the communication between pods within a Kubernetes cluster. They define how pods can communicate with each other and with other network endpoints, helping to secure network traffic.

Why are Network Policies important in Kubernetes?

Network Policies are crucial for securing pod communication, managing traffic flows, and isolating network traffic between different parts of the application. They help enforce security and compliance requirements by controlling which pods can communicate with each other.

How do Network Policies work in Kubernetes?

Network Policies work by specifying rules that are applied to the network traffic between pods. These rules are implemented by the network plugin or CNI (Container Network Interface) used by the Kubernetes cluster. The policies can specify allowed or denied traffic based on pod labels, IP addresses, ports, and protocols.

What is a default Network Policy in Kubernetes?

By default, Kubernetes does not enforce any Network Policies, meaning all pods can communicate with each other. To enforce network segmentation and security, you must explicitly create and apply Network Policies.

Can you apply multiple Network Policies to a single pod?

Yes, you can apply multiple Network Policies to a single pod. Each policy can have different rules, and all applicable policies are evaluated to determine whether traffic should be allowed or denied.

How do you define a Network Policy in Kubernetes?

A Network Policy is defined using a YAML manifest that includes specifications such as podSelector (to select pods), ingress and egress rules (to define allowed or denied traffic), and policyTypes (to indicate whether the policy applies to ingress, egress, or both).

What is the difference between ingress and egress rules in Network Policies?

Ingress rules define the allowed incoming traffic to a pod, specifying which sources can communicate with the pod. Egress rules define the allowed outgoing traffic from a pod, specifying which destinations the pod can communicate with.

How can Network Policies impact service discovery in Kubernetes?

Network Policies can affect service discovery if they restrict traffic between pods that are part of a service. For example, if a policy blocks traffic between the service’s pods and the client pods, it can prevent the service from being reachable.

Are Network Policies supported by all Kubernetes network plugins?

Network Policies are supported by many popular Kubernetes network plugins, but not all. It's important to verify that the network plugin used in your cluster supports Network Policies. Common plugins that support them include Calico, Weave, and Cilium.

How do you test and troubleshoot Network Policies?

To test Network Policies, you can use tools like kubectl exec to run network tests from within pods or use network troubleshooting tools such as tcpdump or netcat. Reviewing the logs of the network plugin and ensuring that the Network Policies are correctly applied and aligned with your security requirements can help troubleshoot issues.
