# Configure Security Settings for Multi-Tenant Deployments

Harden Cortex XSOAR 6.15 multi-tenant deployments with recommended server configurations for secure main and tenant communication.

These recommended security configurations are intended for deployments in which the main account and tenant accounts do not reside in the same DMZ.

| ----------------------------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `security.tenant.use.secret`  | `false` | <p>Generates a unique cookie session for the tenant account and main account.</p><div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p><strong>Note</strong></p><p>If you implement this key in a Multi-tenant high availability architecture, you must restart main host and all of the other hosts.</p></div> |
| `Tenant.AcceptAnyCertificate` | `false` | Validates the host certificate. Set to false if using a CA (certificate authority) signed certificate. Must be set to true if using a self signed certificate, or the main server cannot send requests to hosts.                                                                                                                                |
| `host.insecure`               | `true`  | Trusts any certificate (when host accounts exist).                                                                                                                                                                                                                                                                                              |

## 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/cortex-xsoar-6-multi-tenant-guides/6.15/learn-about-mult-tenant/plan-your-multi-tenant-deployment/configure-security-settings-for-multi-tenant-deployments.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.
