Unauthorized Process Execution

No violationsstackroxhighruntime

This policy generates a violation for any process execution that is not explicitly allowed by a locked process baseline for a given container specification within a Kubernetes deployment.

Rationale: A locked process baseline communicates high confidence that execution of a process not included in the baseline positively indicates malicious activity.
Remediation: Evaluate this process execution for malicious intent, examine other accessible resources for abnormal activity, then kill the pod in which this process executed.
