Unauthorized Network Flow

No violationsstackroxhighruntime

This policy generates a violation for the network flows that fall outside baselines for which 'alert on anomalous violations' is set.

Rationale: The network baseline is a list of flows that are allowed, and once it is frozen, any flow outside that is a concern.
Remediation: Evaluate this network flow. If deemed to be okay, add it to the baseline. If not, investigate further as required.
