# 3.2 Ensure the Apache User Account Has an Invalid Shell

## Profile Applicability

- Level 1

## Description

The `apache` account must not be used as a regular login account, and should be assigned an invalid or `nologin` shell to ensure that the account cannot be used to login.

## Rationale

Service accounts such as the `apache` account represent a risk if they can be used to get a login shell to the system.

## Audit

Check the `apache` login shell in the `/etc/passwd` file:

```bash
# grep apache /etc/passwd
```

The `apache` account shell must be `/sbin/nologin` or `/dev/null` similar to the following:

```
/etc/passwd:apache:x:48:48:Apache:/var/www:/sbin/nologin
```

## Remediation

Change the `apache` account to use the `nologin` shell or an invalid shell such as `/dev/null`:

```bash
# chsh -s /sbin/nologin apache
```

## Default Value

The default Apache user account is `daemon`. The daemon account may have a valid login shell or a shell of `/sbin/nologin` depending on the operating system distribution version.
