# 5.5 Ensure discard is not enabled (Scored)

## Profile Applicability

- Level 1

## Description

`discard` is a network service that simply discards all data it receives. This service is intended for debugging and testing purposes. It is recommended that this service be disabled.

## Rationale

Disabling this service will reduce the remote attack surface of the system.

## Audit Procedure

### Using Command Line

Ensure the `discard` services are not enabled:

```bash
grep ^discard /etc/inetd.conf
```

## Expected Result

No results should be returned.

## Remediation

### Using Command Line

Remove or comment out any `discard` lines in `/etc/inetd.conf`:

```bash
sed -i 's/^discard/#discard/' /etc/inetd.conf
```

## Default Value

Not enabled by default on Ubuntu 12.04 LTS Server.
