-title: Auditing with Falco
----
-
-<!-- overview -->
-### Use Falco to collect audit events
-
-[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.
-
-<!-- body -->
-
-#### Install Falco
-
-Install Falco by using one of the following methods:
-
-- [Standalone Falco](https://falco.org/docs/installation)
-- [Kubernetes DaemonSet](https://falco.org/docs/installation)
-- [Falco Helm Chart](https://github.com/falcosecurity/charts/tree/master/falco)
-
-Once Falco is installed make sure it is configured to expose the Audit webhook. To do so, use the following configuration:
-
-```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.
-
-#### Configure Kubernetes Audit
-
-1. Create a [kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/)
-   for the [kube-apiserver](/docs/reference/generated/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. Start `kube-apiserver` with the following options:
-
-    ```shell
-    --audit-policy-file=/etc/kubernetes/audit-policy.yaml --audit-webhook-config-file=/etc/kubernetes/audit-webhook-kubeconfig
-    ```
-
-#### Audit Rules
-
-Rules devoted to Kubernetes Audit Events can be found in [k8s_audit_rules.yaml](https://github.com/falcosecurity/falco/blob/master/rules/k8s_audit_rules.yaml).
-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:
-
-- 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.
-
-A second class of rules tracks resources being created or destroyed, including:
-
-- 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](https://falco.org/docs/event-sources/kubernetes-audit) in the Falco documentation.
