Deployments with externally exposed endpoints

No violationsstackroxmediumdeploy

Deployments with externally exposed endpoints represent a higher risk

Rationale: Deployments with services exposed outside the cluster are at a higher risk of attempted intrusions because they are reachable outside of the cluster.
Remediation: Verify that service exposure outside of the cluster is required. If the service is only needed for intra-cluster communication, use service type ClusterIP.
