# Security Requirements

**Firewall** - ONEWEB supports firewall to enhance your security. Either hardware or software firewall can be used.

Recommended firewall in ONEWEB Architecture is shown in picture below.

Firewall between Internet and DMZ Zone is the most recommended to protect your application and network from the internet. \
Firewall between DMZ Zone and Internal Network Zone to protect your local network as the second tier from the internet.

As some network security policies may require more firewall added between Application Server and Database Server. ONEWEB also supports that case. But some cases may require firewall policy parameter tuning to prevent database connection problem.

**SSL** - ONEWEB supports **SSL/TLS** using Application Server features such as Wildfly, JBoss EAO or IBM WebSphere Application Server. You can configure SSL Certificate at Application Server which commonly supports Self Sign Certificate or Certificate from CA.

## 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://docs.oneweb.tech/oneweb/install-and-configure-oneweb-platform/plan-your-oneweb-installation/check-prerequisite-for-oneweb-installation/security-requirements.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.
