### 使用Falco采集审计事件

<!--
|

[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/）是一个用于云原生平台入侵和异常检测开源项目。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]
|
||||
-->
|
||||
- [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.
|
||||
-->
|
||||
配置通常可以在`/ etc / falco / falco.yaml`文件中找到。 如果Falco作为Kubernetes DaemonSet安装，请编辑`falco-config` ConfigMap并添加此配置。
|
||||
<!--

||||
#### Configure Kubernetes Audit
|
||||

|
||||
#### 配置Kubernetes审计
|
||||
|
||||
<!--
|
||||
1. Create a [kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/) for the [kube-apiserver][kube-apiserver] webhook audit backend.
|
||||
|
||||
cat <<EOF > /etc/kubernetes/audit-webhook-kubeconfig
|
||||
apiVersion: v1
|
||||
kind: Config
|
||||
clusters:
|
||||
- cluster:
|
||||
server: http://<ip_of_falco>:8765/k8s_audit
|
||||
name: falco
|
||||
contexts:
|
||||
- context:
|
||||
cluster: falco
|
||||
user: ""
|
||||
name: default-context
|

current-context: default-context
|

preferences: {}
|
||||
users: []
|
||||
EOF
|
||||
-->
|
||||
1. 为 [kube-apiserver][kube-apiserver] webhook 审计后端创建一个[kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/)配置文件。
|
||||
|
||||
cat <<EOF > /etc/kubernetes/audit-webhook-kubeconfig
|
||||
apiVersion: v1
|
||||
kind: Config
|
||||
clusters:
|
||||
- cluster:

||||
server: http://<ip_of_falco>:8765/k8s_audit
|
||||
name: falco
|
||||
contexts:

||||
- context:
|
||||
cluster: falco
|
||||
user: ""
|
||||
name: default-context
|
||||
current-context: default-context
|
||||
preferences: {}
|
||||
users: []
|
||||
EOF
|
||||
<!--
|
||||
1. Start [kube-apiserver][kube-apiserver] with the following options:
|
||||
|
||||
```shell
|
||||
--audit-policy-file=/etc/kubernetes/audit-policy.yaml --audit-webhook-config-file=/etc/kubernetes/audit-webhook-kubeconfig
|
||||
```
|
||||
-->
|
||||
2. 使用以下选项开启 [kube-apiserver][kube-apiserver]:
|
||||
|
||||
```shell
|
||||
--audit-policy-file=/etc/kubernetes/audit-policy.yaml --audit-webhook-config-file=/etc/kubernetes/audit-webhook-kubeconfig
|
||||
```
|
||||
<!--
|
||||
#### 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Audit Rules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，以便可以使用。
|
||||
|
||||
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。
|
||||
-使用通配动词或资源创建ClusterRole。 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。
|
||||
|
||||
有关更多详细信息，请参阅Falco文档中的[Kubernetes审计事件][falco_ka_docs]。
