name: Default Namespace Usage in Deployments

description: Checks if Kubernetes Deployments are using the default namespace, which can lead to security risks and mismanagement issues.
|
|
impact: |
|
|
Using the default namespace for Kubernetes Deployments can increase security risks as it might allow broader access than necessary. It also complicates resource management across multiple teams and applications.
|
|
remediation: |
|
|
Avoid using the default namespace for Kubernetes Deployments. Create and specify dedicated namespaces tailored to specific applications or teams to enhance security and manage resources effectively.
