# 4.6.3 Apply Security Context to Pods and Containers (Manual)

## Profile Applicability

- Level 2

## Description

Apply Security Context to Pods and Containers.

## Rationale

A security context defines the operating system security settings (uid, gid, capabilities, SELinux role, etc..) applied to a container. When designing containers and pods, make sure that the security context is configured for pods, containers, and volumes. A security context is a property defined in the deployment yaml. It controls the security parameters that will be assigned to the pod/container/volume. There are two levels of security context: pod level security context, and container level security context.

## Impact

If you incorrectly apply security contexts, there may be issues running the pods.

## Audit

Review the pod definitions in the cluster and verify that the security contexts have been defined as appropriate.

## Remediation

Follow the Kubernetes documentation and apply security contexts to your pods. For a suggested list of security contexts, you may refer to the CIS Google Container-Optimized OS Benchmark.

## Default Value

By default, no security contexts are automatically applied to pods.
