# 2.2.6 Ensure RPC is not installed (Automated)

## Description

Remote Procedure Call (RPC) is a method for creating low level client server applications across different system architectures. It requires an RPC compliant client listening on a network port. The supporting package is rpcbind.

## Rationale

If RPC is not required, it is recommended that this services be removed to reduce the remote attack surface.

## Audit Procedure

### Command Line

Run the following command to verify rpcbind is not installed:

```bash
dpkg -s rpcbind | grep -E '(Status:|not installed)'
```

## Expected Result

```
dpkg-query: package 'rpcbind' is not installed and no information is available
```

## Remediation

### Command Line

Run the following command to remove rpcbind:

```bash
apt purge rpcbind
```

## Default Value

rpcbind is not installed on minimal server installations.
