# Security Policy

| [Read here to learn about CentOS 7 reaching EOL](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/operations/centos-7-eol/README.md) |

The TelcoBridges Operating Software runs over a variant of CentOS 5, CentOS 7, or Telcobridges linux that is managed by TelcoBridges. The resulting operating system is a selected set of binary packages maintained by Telcobridges.

#### Security Update Procedure

When a new security update is available, TelcoBridges follows a rigorous security update procedure:

1. first check if the affected packages are in one of our repositories.
2. insert affected packages in our internal TelcoBridges repository for regression testing
3. after a few weeks of testing, insert the package in the **official** repository

## 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://prosbcdocs.telcobridges.com/tmedia-documentation/server-and-os-administration/security-policy.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.
