[Falco](https://falco.org/) is an open source project for intrusion and abnormality detection for Cloud Native platforms.
|
||||||
|
This section describes how to set up Falco, how to send audit events to the Kubernetes Audit endpoint exposed by Falco, and how Falco applies a set of rules to automatically detect suspicious behavior.
|
||||||
|
-->
|
||||||
|
[Falco](https://falco.org/)是一个开源项目,用于为云原生平台提供入侵和异常检测。本节介绍如何设置 Falco、如何将审计事件发送到 Falco 公开的 Kubernetes Audit 端点、以及 Falco 如何应用一组规则来自动检测可疑行为。

#### 安装 Falco
|
||||||
|
|
||||||
|
<!--
|
||||||
|
Install Falco by using one of the following methods:
|
||||||
|
-->
|
||||||
|
使用以下方法安装 Falco :
|
||||||
|
|
||||||
|
<!--
|
||||||
|
- [Standalone Falco][falco_installation]
|
||||||
|
- [Kubernetes DaemonSet][falco_installation]
|
||||||
|
- [Falco Helm Chart][falco_helm_chart]

||||||

|
||||||
|
|
||||||
|
<!--
|
||||||
|
Once Falco is installed make sure it is configured to expose the Audit webhook. To do so, use the following configuration:
|
||||||
|
-->
|
||||||
|
安装完成 Falco 后,请确保将其配置为公开 Audit Webhook。为此,请使用以下配置:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
webserver:
|
||||||
|
enabled: true
|
||||||
|
listen_port: 8765
|
||||||
|
k8s_audit_endpoint: /k8s_audit
|
||||||
|
ssl_enabled: false
|
||||||
|
ssl_certificate: /etc/falco/falco.pem
|
||||||
|
```
|
||||||
|
|
||||||
|
<!--
|
||||||
|
This configuration is typically found in the `/etc/falco/falco.yaml` file. If Falco is installed as a Kubernetes DaemonSet, edit the `falco-config` ConfigMap and add this configuration.
|
||||||
|
-->
|
||||||
|
此配置通常位于 `/etc/falco/falco.yaml` 文件中。如果 Falco 作为 Kubernetes DaemonSet 安装,请编辑 `falco-config` ConfigMap 并添加此配置。

1. Create a [kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/) for the [kube-apiserver][kube-apiserver] webhook audit backend.
|
||||||
|
|
||||||
|

1. 为 [kube-apiserver][kube-apiserver] webhook 审计后端创建一个[kubeconfig](/docs/concepts/configuration/organize-cluster-access-kubeconfig/)文件。

|
cat <<EOF > /etc/kubernetes/audit-webhook-kubeconfig

1. Start [kube-apiserver][kube-apiserver] with the following options:

#### Audit Rules
|
||||||

-->
|
||||||
|
#### 审计规则
|
||||||
|
|
||||||
|
<!--
|
||||||
|
Rules devoted to Kubernetes Audit Events can be found in [k8s_audit_rules.yaml][falco_k8s_audit_rules]. If Audit Rules is installed as a native package or using the official Docker images, Falco copies the rules file to `/etc/falco/`, so they are available for use.
|
||||||
|
|
||||||
|
There are three classes of rules.
|
||||||
|
|
||||||
|
The first class of rules looks for suspicious or exceptional activities, such as:
|
||||||
|
-->
|
||||||
|
|
||||||
|
专门用于 Kubernetes 审计事件的规则可以在 [k8s_audit_rules.yaml][falco_k8s_audit_rules] 中找到。如果审计规则是作为本机软件包安装或使用官方 Docker 镜像安装的,则 Falco 会将规则文件复制到 `/etc/falco/` 中以便使用。
|
||||||
|
|
||||||
|
共有三类规则。
|
||||||
|
|
||||||
|
第一类规则用于查找可疑或异常活动,例如:
|
||||||
|
|
||||||
|
<!--
|
||||||
|
- Any activity by an unauthorized or anonymous user.
|
||||||
|
- Creating a pod with an unknown or disallowed image.
|
||||||
|
- Creating a privileged pod, a pod mounting a sensitive filesystem from the host, or a pod using host networking.
|
||||||
|
- Creating a NodePort service.
|
||||||
|
- Creating a ConfigMap containing private credentials, such as passwords and cloud provider secrets.
|
||||||
|
- Attaching to or executing a command on a running pod.
|
||||||
|
- Creating a namespace external to a set of allowed namespaces.
|
||||||
|
- Creating a pod or service account in the kube-system or kube-public namespaces.
|
||||||
|
- Trying to modify or delete a system ClusterRole.
|
||||||
|
- Creating a ClusterRoleBinding to the cluster-admin role.
|
||||||
|
- Creating a ClusterRole with wildcarded verbs or resources. For example, overly permissive.
|
||||||
|
- Creating a ClusterRole with write permissions or a ClusterRole that can execute commands on pods.
|
||||||
|
-->
|
||||||
|
-未经授权或匿名用户的任何活动。
|
||||||
|
-创建使用未知或不允许的镜像的 pod。
|
||||||
|
-创建特权 Pod,从主机安装敏感文件系统的 Pod 或使用主机网络的 Pod。
|
||||||
|
-创建 NodePort 服务。
|
||||||
|
-创建包含私有证书(例如密码和云提供商 secrets )的 ConfigMap。
|
||||||
|
-在正在运行的 Pod 上附加或执行命令。
|
||||||
|
-在一组允许的名称空间之外创建一个名称空间。
|
||||||
|
-在 kube-system 或 kube-public 命名空间中创建 pod 或服务帐户。
|
||||||
|
-尝试修改或删除系统 ClusterRole。
|
||||||
|
-创建一个 ClusterRoleBinding 到 cluster-admin 角色。
|
||||||
|
-创建 ClusterRole 时在动词或资源中使用通配符。 例如,过度赋权。
|
||||||
|
-创建具有写权限的 ClusterRole 或可以在 Pod 上执行命令的 ClusterRole。
|
||||||
|
|
||||||
|
<!--
|
||||||
|
A second class of rules tracks resources being created or destroyed, including:
|
||||||
|
|
||||||
|
- Deployments
|
||||||
|
- Services
|
||||||
|
- ConfigMaps
|
||||||
|
- Namespaces
|
||||||
|
- Service accounts
|
||||||
|
- Role/ClusterRoles
|
||||||
|
- Role/ClusterRoleBindings
|
||||||
|
-->
|
||||||
|
第二类规则跟踪正在创建或销毁的资源,包括:
|
||||||
|
|
||||||
|
- Deployments
|
||||||
|
- Services
|
||||||
|
- ConfigMaps
|
||||||
|
- Namespaces
|
||||||
|
- Service accounts
|
||||||
|
- Role/ClusterRoles
|
||||||
|
- Role/ClusterRoleBindings
|
||||||
|
|
||||||
|
<!--
|
||||||
|
The final class of rules simply displays any Audit Event received by Falco. This rule is disabled by default, as it can be quite noisy.
|
||||||
|
|
||||||
|
For further details, see [Kubernetes Audit Events][falco_ka_docs] in the Falco documentation.
|
||||||
|
-->
|
||||||
|
|
||||||
|
最后一类规则仅负责显示 Falco 收到的所有审核事件。默认情况下,此规则是禁用的,因为它可能会很吵。
|
||||||
|
|
||||||
