cyberstrikeus 5.10.5 Enable Security Posture (Manual)
Profile Applicability
- Level 2
Description
Enable Security Posture to gain insights about your workload security posture at the runtime phase of the software delivery life-cycle.
Rationale
The security posture dashboard provides insights about your workload security posture at the runtime phase of the software delivery life-cycle.
Impact
GKE security posture configuration auditing checks your workloads against a set of defined best practices. Each configuration check has its own impact or risk. Learn more about the checks: https://cloud.google.com/kubernetes-engine/docs/concepts/about-configuration-scanning
Example: The host namespace check identifies pods that share host namespaces. Pods that share host namespaces allow Pod processes to communicate with host processes and gather host information, which could lead to a container escape.
Audit
Check the SecurityPostureConfig on your cluster:
gcloud container clusters --location describe
The output should include:
securityPostureConfig:
mode: BASIC
Remediation
Enable security posture via the UI, gCloud or API.
See: https://cloud.google.com/kubernetes-engine/docs/how-to/protect-workload-configuration
Default Value
GKE security posture has multiple features. Not all are on by default. Configuration auditing is enabled by default for new standard and autopilot clusters.
