# Ensure ServerSignature Is Not Enabled

## Description

Disable the server signatures, which is the generation of a signature line as a trailing footer at the bottom of server-generated documents such as error pages.

## Rationale

Server signatures are helpful when the server is acting as a proxy because they help the user distinguish errors from the proxy rather than the destination server. However, in this context there is no need for the additional information.

## Audit

Perform the following steps to determine if the recommended state is implemented:

Verify the ServerSignature directive is either NOT present in the Apache configuration or is present and has a value of Off.

## Remediation

Perform the following to implement the recommended state:

Add or modify the ServerSignature directive as shown below to have the value of Off:

```
ServerSignature Off
```

## Default Value

```
Off
```
