## Impact

Using the Linux capabilities feature you can grant certain privileges to a process without granting all the privileges of the root user. Added capabilities entitle containers in a pod with additional privileges that can be used to change core processes and networking settings of a cluster. We recommend you only use privileges that are required for the proper function of the cluster. To add or remove Linux capabilities for a container, you can include the capabilities field in the *securityContext* section of the container manifest.

## How to Fix

*Resource:* PodSecurityPolicy

* *Arguments:* allowedCapabilities (Optional)

Provides a list of capabilities that may be added to a container beyond the default set.

To use a *PodSecurityPolicy* resource, the requesting user or target pod’s service account must be authorized to use the policy. The preferred method is to grant access to the service account. In the following example we use *RBAC*, a standard Kubernetes authorization mode.

A *Role* or *ClusterRole* needs to grant access to use the desired policies.

The *ClusterRole* is then bound to the authorized service(s):

## *Kind*: ClusterRoleBinding \[source,go]

* allowedCapabilities:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/compute/appsec-k8s-24.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
