Each pod has its security context.
Use security policies to ensure containers run with the correct permissions and restrictions.
Avoid running as a root user or any other highly privileged user.
Ensure any secrets used by the pods are limited in scope and impact.
Avoid hardcoding sensitive information like passwords and API tokens directly in your pod configurations.
Instead, use Kubernetes Secrets to store and manage such information securely.
Configure your pods to use read-only filesystems whenever possible. It prevents potential attackers from modifying container files, which can help mitigate certain security breaches.
Resource limits and requests can prevent resource exhaustion and abuse. Define appropriate resource limits for your containers to avoid consuming excessive CPU, memory, or other resources.
Network policies control communication between pods and are instrumental in segmenting your application. By allowing only necessary communication and denying the rest, you reduce the attack surface and limit the lateral movement of threats.
