Certified Kubernetes Security Specialist (CKS) Questions and Answers

Question 1

Context

A default-deny NetworkPolicy avoids to accidentally expose a Pod in a namespace that doesn't have any other NetworkPolicy defined.

Task

Create a new default-deny NetworkPolicy named defaultdeny in the namespace testing for all traffic of type Egress.

The new NetworkPolicy must deny all Egress traffic in the namespace testing.

Apply the newly created default-deny NetworkPolicy to all Pods running in namespace testing.

Question 2

You can switch the cluster/configuration context using the following command:

[desk@cli] $ kubectl config use-context test-account

Task: Enable audit logs in the cluster.

To do so, enable the log backend, and ensure that:

1. logs are stored at /var/log/Kubernetes/logs.txt

2. log files are retained for 5 days

3. at maximum, a number of 10 old audit log files are retained

A basic policy is provided at /etc/Kubernetes/logpolicy/audit-policy.yaml. It only specifies what not to log.

Note: The base policy is located on the cluster's master node.

Edit and extend the basic policy to log:

1. Nodes changes at RequestResponse level

2. The request body of persistentvolumes changes in the namespace frontend

3. ConfigMap and Secret changes in all namespaces at the Metadata level

Also, add a catch-all rule to log all other requests at the Metadata level

Note: Don't forget to apply the modified policy.

Answer:

See the explanation below

Explanation:

$ vim /etc/kubernetes/log-policy/audit-policy.yaml

- level: RequestResponse

userGroups: ["system:nodes"]

- level: Request

resources:

- group: "" # core API group

resources: ["persistentvolumes"]

namespaces: ["frontend"]

- level: Metadata

resources:

- group: ""

resources: ["configmaps", "secrets"]

- level: Metadata

$ vim /etc/kubernetes/manifests/kube-apiserver.yaml

Add these

- --audit-policy-file=/etc/kubernetes/log-policy/audit-policy.yaml

- --audit-log-path=/var/log/kubernetes/logs.txt

- --audit-log-maxage=5

- --audit-log-maxbackup=10

Explanation[desk@cli] $ ssh master1

[master1@cli] $ vim /etc/kubernetes/log-policy/audit-policy.yaml

apiVersion: audit.k8s.io/v1 # This is required.

kind: Policy

# Don't generate audit events for all requests in RequestReceived stage.

omitStages:

- "RequestReceived"

rules:

# Don't log watch requests by the "system:kube-proxy" on endpoints or services

- level: None

users: ["system:kube-proxy"]

verbs: ["watch"]

resources:

- group: "" # core API group

resources: ["endpoints", "services"]

# Don't log authenticated requests to certain non-resource URL paths.

- level: None

userGroups: ["system:authenticated"]

nonResourceURLs:

- "/api*" # Wildcard matching.

- "/version"

# Add your changes below

- level: RequestResponse

userGroups: ["system:nodes"] # Block for nodes

- level: Request

resources:

- group: "" # core API group

resources: ["persistentvolumes"] # Block for persistentvolumes

namespaces: ["frontend"] # Block for persistentvolumes of frontend ns

- level: Metadata

resources:

- group: "" # core API group

resources: ["configmaps", "secrets"] # Block for configmaps & secrets

- level: Metadata # Block for everything else

[master1@cli] $ vim /etc/kubernetes/manifests/kube-apiserver.yaml

apiVersion: v1

kind: Pod

metadata:

annotations:

kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint: 10.0.0.5:6443

labels:

component: kube-apiserver

tier: control-plane

name: kube-apiserver

namespace: kube-system

spec:

containers:

- command:

- kube-apiserver

- --advertise-address=10.0.0.5

- --allow-privileged=true

- --authorization-mode=Node,RBAC

- --audit-policy-file=/etc/kubernetes/log-policy/audit-policy.yaml #Add this

- --audit-log-path=/var/log/kubernetes/logs.txt #Add this

- --audit-log-maxage=5 #Add this

- --audit-log-maxbackup=10 #Add this

output truncated

Note: log volume & policy volume is already mounted in vim /etc/kubernetes/manifests/kube-apiserver.yaml so no need to mount it.

[Reference: https://kubernetes.io/docs/tasks/debug-application-cluster/audit/, ]

Question 3

Context

The kubeadm-created cluster's Kubernetes API server was, for testing purposes, temporarily configured to allow unauthenticated and unauthorized access granting the anonymous user duster-admin access.

Task

Reconfigure the cluster's Kubernetes API server to ensure that only authenticated and authorized REST requests are allowed.

Use authorization mode Node,RBAC and admission controller NodeRestriction.

Cleaning up, remove the ClusterRoleBinding for user system:anonymous.
