Key Concepts Covered in a CKSS Udemy Course

A comprehensive CKSS Udemy course will delve into various critical security aspects of Kubernetes. Let's break down some of the core concepts you'll encounter:

1. Kubernetes Security Contexts

Security Contexts are fundamental to securing your Kubernetes pods and containers. They allow you to define privilege and access control settings. This includes:

  • Running as Non-Root: Configuring containers to run as non-root users is a primary security measure. It reduces the risk of privilege escalation if a container is compromised.
  • Capabilities: Kubernetes capabilities provide granular control over process privileges. You can drop unnecessary capabilities to minimize the attack surface.
  • Read-Only Root Filesystems: Making the root filesystem read-only can prevent unauthorized modifications to the container's filesystem.
  • Privilege Escalation: Controlling whether a process can gain more privileges than its parent process is crucial for preventing privilege escalation attacks.

2. Network Policies

Network Policies are Kubernetes resources that control the network traffic between pods. They allow you to isolate workloads and restrict communication to only what is necessary. Key aspects include:

  • Ingress and Egress Rules: Defining rules for both inbound and outbound traffic ensures that only authorized communication is allowed.
  • Namespace Isolation: Implementing network policies to isolate namespaces prevents unauthorized access between different environments.
  • Policy Enforcement: Understanding how Kubernetes network policy engines enforce these policies is essential for effective security.

3. Role-Based Access Control (RBAC)

RBAC is a crucial component of Kubernetes security, enabling you to manage access to Kubernetes resources. It involves:

  • Roles and ClusterRoles: Defining roles with specific permissions and assigning them at the namespace or cluster level.
  • RoleBindings and ClusterRoleBindings: Binding roles to users, groups, or service accounts to grant them the necessary permissions.
  • Least Privilege Principle: Applying the principle of least privilege to ensure users and applications have only the permissions they need.

4. Secrets Management

Securely managing secrets is critical for protecting sensitive data in Kubernetes. Key practices include:

  • Storing Secrets Securely: Using Kubernetes Secrets objects to store sensitive information such as passwords, API keys, and certificates.
  • Encryption at Rest: Encrypting secrets at rest to protect them from unauthorized access if the etcd datastore is compromised.
  • Limiting Access to Secrets: Restricting access to secrets using RBAC and other security measures.

5. Auditing and Logging

Monitoring and auditing Kubernetes activity is essential for detecting and responding to security incidents. Key aspects include:

  • Configuring Audit Logging: Setting up Kubernetes audit logging to record all API requests and events.
  • Analyzing Audit Logs: Using tools and techniques to analyze audit logs for suspicious activity.
  • Centralized Logging: Integrating Kubernetes logs with a centralized logging system for easier monitoring and analysis.

6. Image Security

Container images are a critical part of the Kubernetes ecosystem, and securing them is essential for preventing vulnerabilities. Key practices include:

  • Scanning Images for Vulnerabilities: Using tools to scan container images for known vulnerabilities before deploying them to Kubernetes.
  • Base Image Selection: Choosing minimal base images to reduce the attack surface.
  • Image Signing and Verification: Signing container images to ensure their authenticity and verifying signatures before deployment.

7. Admission Controllers

Admission Controllers are Kubernetes components that intercept API requests before they are persisted to the etcd datastore. They can be used to enforce security policies and prevent misconfigurations. Key aspects include:

  • Using Built-in Admission Controllers: Enabling and configuring built-in admission controllers such as PodSecurityPolicy and DenyEscalatingExec.
  • Writing Custom Admission Controllers: Developing custom admission controllers to enforce organization-specific security policies.
