Hi!
The following table lists the alerts that were deprecated:
Alert name | Description | Tactics | Severity |
---|---|---|---|
Docker build operation detected on a Kubernetes node (VM_ImageBuildOnNode) | Machine logs indicate a build operation of a container image on a Kubernetes node. While this behavior might be legitimate, attackers might build their malicious images locally to avoid detection. | Defense Evasion | Low |
Suspicious request to Kubernetes API (VM_KubernetesAPI) | Machine logs indicate that a suspicious request was made to the Kubernetes API. The request was sent from a Kubernetes node, possibly from one of the containers running in the node. Although this behavior can be intentional, it might indicate that the node is running a compromised container. | LateralMovement | Medium |
SSH server is running inside a container (VM_ContainerSSH) | Machine logs indicate that an SSH server is running inside a Docker container. While this behavior can be intentional, it frequently indicates that a container is misconfigured or breached. | Execution | Medium |
These alerts are used to notify a user about suspicious activity connected to a Kubernetes cluster. The alerts will be replaced with matching alerts that are part of the Microsoft Defender for Cloud Container alerts (K8S.NODE_ImageBuildOnNode
, K8S.NODE_ KubernetesAPI
and K8S.NODE_ ContainerSSH
) which will provide improved fidelity and comprehensive context to investigate and act on the alerts.
