# View and Modify Use of Security Modules

All the relevant security modules used by your device's Cortex XDR app are displayed on the **Modules** screen. Your device only displays the security modules that have been defined for your device by your system administrator. These modules can vary, depending on device type (phone or stationary device), organization-managed or your own personal device (BYOD), and other factors or policies.

Some modules are fully managed by your system administrator (such as the Network Shield module), and some can be activated or disabled locally on your device. Some modules must be activated in order to achieve **Fully protected** status, and some modules are optional.

* If a module requires some action on your part, this is indicated for the module, and **Activate** is displayed. Tap **Activate** to open an onboarding screen that will guide you through the required steps.
* If a modules displays **Controlled by admin**, you cannot disable it.
* If an active module displays **Disable**, you can tap this to disable it. We recommend that you do not disable required security modules, because if you do so, your device will not be fully protected.
* If the Safari Safeguard module is optional on your device, and you activate it, alerts will only be visible locally on your device and will not be forwarded to your organization. If the module is required, and activated, alerts will be forwarded.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-agent-ios-guide/8.5/device-user-tasks/view-and-modify-use-of-security-modules.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
