Key Concepts
Authentication
Verifying the identity of users and service accounts accessing the cluster.
- • Service account tokens
- • User authentication methods
- • Authentication webhooks
- • OIDC and OAuth integration
RBAC
Role-based access control for managing permissions and access to resources.
- • Roles and RoleBindings
- • ClusterRoles and ClusterRoleBindings
- • Resource and verb permissions
- • API group access control
Pod Security
Securing pods and containers with security contexts and policies.
- • Security contexts
- • Pod security standards
- • Seccomp and AppArmor profiles
- • SELinux policies
Network Policies
Controlling network traffic between pods and namespaces.
- • Ingress and egress rules
- • Pod and namespace selectors
- • Port and protocol restrictions
- • Default deny policies
Security Best Practices
Principle of Least Privilege
Grant only the minimum permissions required for users and service accounts.
Network Segmentation
Use network policies to isolate traffic between different application tiers.
Regular Auditing
Monitor and audit access patterns and security events in your cluster.
