# 2. Secure Configuration

The goal of this control is to ensure devices are properly configured with secure settings.

This control expects organisations to:

* Actively manage computers and network devices by:
  * Removing and disabling unnecessary user accounts.
  * Changing default and weak passwords.
  * Removing or disabling any unnecessary applications, system utilities, and network services.
  * Disabling auto-run features which allow file execution without user authorisation (such as when they are downloaded from the Internet).
  * Authenticating users before allowing them access to organisational data or services.
  * Activating device locking controls to protect against unauthorised physical access.
* Implementing device unlocking credentials such as:
  * Protecting devices with a password, PIN, or biometric test.
  * Protecting passwords, PINS, and biometric tests from brute-forcing by:
    * Configuring wait times between attempts. These should allow no more than 10 guesses in 5 minutes.
    * Locking devices after no more than 10 unsuccessful attempts.
  * Mandating a minimum length of 6 characters where passwords or PINs are used as the sole method of unlocking a device.

## 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://manual.harpe.io/start/cyber-essentials-wiki/controls/2.-secure-configuration.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.
