This document describes a threat finding type in Security Command Center. Threat findings are generated by threat detectors when they detect a potential threat in your cloud resources. For a full list of available threat findings, see Threat findings index.
Overview
A root certificate was installed on the node. Adversaries may install a root certificate to avoid security alerts when establishing connections to their malicious web servers. Attackers could carry out man-in-the-middle attacks, intercepting sensitive data exchanged between the victim and the adversary's servers, without triggering any warnings. This is a file monitoring detector and has specific GKE version requirements. This detector is disabled by default. For instructions on how to enable it, see Testing Container Threat Detection.
Container Threat Detection is the source of this finding.
